Might be a duplicate of http://code.google.com/p/chromium/issues/detail?id=136416, which seems to be a problem with pepper flash.

Labels: Feature-Flash
There seems to be a split here, where Vista is significantly more problematic than Win7. So, right now lets keep this separate from bug 136416.

Summary: Sound is choppy or distorted (was: NULL)
Moving all non essential bugs to the next Milestone
I see that jschuh thinks this should be kept separate, but I feel it's appropriate to point out here that issue 136416 is a duplicate of issue 135178, which has already been assigned, and that this does seem to be the same issue.
Gah, sorry for the double comment, but I also feel I should say that I don't know exactly what users have been saying in the reports, as I don't have the privliges to read the reports. I'm going solely off the idea of distorted sound in the pepper flash player.

We're getting reports about this in the forum as well. Users on Beta 21.0.1180.15 with pepflashplayer.dll find that sound is distorted or choppy. Most are in Win Vista so far. 

Justin, what kind of hardware specs would be useful in further investigation?

It's wide open at the moment. So basically any detail they can give would help. We're setting up a Vista test machine tomorrow to see what we can deduce.

Flash player and Chrome updated today(7/13), but still same problem, and still the same work around.

disable pepflashplayer.dll (old version 11.3.31.208, new 11.3.31.218)

and leave enabled both gcswf32.dll and NPSWF32~.dll (old versions 11,3,300,257, new 11,3,300,265)

vtl is looking at this.
I have popping and cracking on sites with Crome but not with IE and Firefox. 22.0.1207.0 canary
Windows 8 RP


The problem is still there on the new dev version.
Audio clipped, distorted after 1 or 2 min playing.
I use Windows Seven.

Chrome Version       :  22.0.1207.1 dev-m
OS Version: 6.1 (Windows 7, 7601 SP1)

I am also still experiencing this with the latest beta (21.0.1180.49 beta-m)
on Windows 7 Ultimate x64.  The noted workaround solves things for me until a fix is put in.
for the rest, this workaround worked for me.

There may be several issues here -- one related to new audio mixing code in Chrome, and one related to Pepper.

Could everyone who's having this issue (especially if you see it on Chrome 21 Beta, and especially if you're on Windows Vista or XP) try the latest Canary (Flash version 11.3.31.303)? (Hopefully, any new audio mixing problems won't cause confusion; in any case, if there are still problems, but *different* problems, that would still be interesting to know.) Thanks.
@Viet, Do you want issue http://code.google.com/p/chromium/issues/detail?id=135178 to be merged into this one? It seems similar.
Temporary fix:

In Chrome put into the address bar:  chrome://plugins/

At the top right click on details

Disable: pepflashplayer.dll
Disable: NPSWF32_11_3_300_265.dll

Leave enabled: gcswf32.dll

Close and relaunch Chrome.  Youtube will work for now.  Anything relying on pepper will not work, but for me this works great.

I should note, pepflashplayer.dll and NPSWF32_11_3_300_265.dll are 2 of the 3 flash files and are in the flash section on the chrome://plugins/ details page.

Please ignore the comment #19. Previous plugin versions will not be supported going forward, and you're putting yourself at serious risk by disabling the current plugin.

@Comment17 I'm observing this issue with pepper flash v11.3.31.303 in canary 22.0.1216.0 (r148053) running on Win7 x64.  It seems to occur with all streaming flash audio.

I also get the audio stutter with the pepflash.  Reverting to the older version works.  The main reason I am posting is because I also have a X-Fi Sound Blaster

Aaargh, chrome keeps defaulting to pepflashplayer even though I disable it , it's crap I want to disable it for good.

I get audio static and poor performance when using the PPAPI flash plugin on Fedora Linux x86_64. Disabling the PPAPI plugin makes the static go away and the perfornance improve, but it's still not as good as the performance under Firefox. I've got google-chrome-stable-20.0.1132.57-145807.x86_64 and Version 11.3.31.115 of libpepflashplayer.so.

Confirmed crackling audio with chrome 21.0.1180.57 using pepperflash.  I had been using the work around (disabling pepperflash), but NBCOlympics.com only works with pepperflash.... (authentication loop with standard flash) so I have garbled olympics now.

Disabling pepflashplayer.dll as a workaround is successful.
Issue 134377 has been merged into this issue.
@viettrungluu I can reproduce on my home machine with SB X-Fi. And there is no issue if I switch to internal Reatek HD audio.
So far, I've been unable to reproduce with a SB X-Fi Xtreme Audio PCI Express (on Win 7 64-bit).... :/

I'd appreciate it if people who are experiencing problems give more information about:
- audio configuration (sampling rate settings, effects, speaker configuration -- e.g., 5.1, etc.)
- exact model number, PCI versus PCI Express
- processor, memory, etc.
In addition to:
- OS version
- Chrome and Flash version
- sound card type and driver version

Also, if you're experiencing the problem with a completely off-the-shelf system, please let us know! -- we might be able to go and get one.
Would it be useful if I try to localize CL that introduce the issue?
@45: No.
Could everyone who's having problems try setting their speaker config to 2/2.1 speakers and let me know if that improves things? Thanks.

Issue 139543 has been merged into this issue.
Okay, for anyone who's seeing this problem, could you try setting the default audio format to 44100 Hz (16-bit)? (Mixer -> click on your speaker to get Speakers Properties -> Advanced -> Default Format on Windows 7. Note that there may be other places which claim to affect this setting, but actually have no effect.)
Ok. So I re-enabled the pepflash plugin, changed the audio format to 44100, 16-bit, restarted Chrome, and it works.  Prior to the change it was set to 24-bit, 48000Hz (Studio Quality).
With 22.0.1207.1 dev

Problem with 16 or 24 bits, 48000HZ
Also problem with 16 or 24 bits, 44100Hz, but less often.

Sound is distorded after 1 min or more during 5 seconds (up to 3 min without problem in 16 bits 44100 Hz, but depends on the song)

Per request, I've just re-enabled the pepflash plugin and updated to the latest beta version, and the changes did correct the issue for me.  I am no longer experiencing the problem.
Comment 60 by jtan@chromium.org, Jul 31 2012
We just pushed a new update to Beta (version 21.0.1180.60). Can those of you experiencing this issue verify if this latest version resolves the choppy/distorted sound on Pepper Flash (pepflashplayer.dll)? 

Update by going to wrench menu -> About Google Chrome, and ensure that you're still using Pepper Flash by going to the about:plugins page and checking that it hasn't been disabled. I contacted a few of you offline via email to verify this as well. If you can let us know the results here, that would be great. Thanks.

I test the new beta version. It seems ok too. No audio issues after playing 3 videos.

I'm waiting an update for dev version, to confirm too.
Comment 65 by Deleted ...@, Jul 31 2012
Having issues with anything Flash related in Chrome. Videos on YouTube do not produce any sound and would only play for exactly 3 seconds before stopping. Buffering continues normally, however. On Pandora, no sound is produced and tracks are continuously skipped after 3 seconds on each track.

Specs (custom build desktop):

-Google Chrome version 21.0.1180.60 m
-Flash Player version 11.3.31.222
-Windows 7 Ultimate 64 bit Service Pack 1
-Diamond XtremeSound 7.1
  -Driver version 7.12.8.1740
-MSI Geforce 560TI N560GTX-TI Twin Frozr II
-5.1 speaker configuration through Dolby Digital S/PDIF

I hope this helps!
Comment 66 by Deleted ...@, Aug 1 2012
Problem that I reported on beta channel has now moved to stable channel.  Confirmed no audio and video constantly pauses on YouTube.

Chrome: 21.0.1180.60 m
Flash:11.3.31.222 (Shockwave Flash 11.3 r31)
OS: Windows 7 SP1 64-bit
Audio Driver: IDT (6.10.0.6341)
I think that the problem should be fixed for the majority of users (which doesn't help those who are still affected).

@65 (Om.drwsh):
- Does it help if you change your speaker configuration to 2/2.1?
- What is your default sample rate/format (Mixer -> click on your speaker to get Speakers Properties -> Advanced -> Default Format)? Does changing it affect things?
- Do you have any other post-processing enabled through your audio driver? (If yes, does disabling it help?)

@66 (andrew@junglebase.com):
- Is your sound provided by a sound card or built in to your motherboard?
- What's your speaker configuration? 2/2.1? 5/5.1? 7/7.1? If it's not 2/2.1, does it help to change it to that?
- Also what's your default sample rate/format (see above) and does changing it affect things?
- Do you have any other post-processing enabled through your audio driver? (If yes, does disabling it help?)

Thanks.

Comment 69 by Deleted ...@, Aug 1 2012
Answers to #67

- Built in sound chipset from a Dell Vostro 3350 motherboard / AND / Logitech USB device
- 2 speaker stereo (well...see important note below)
- 16 bit/48kHz (IDT) / 16 bit/44.1kHz (USB)
- Yes, "Dell Audio by IDT".  Looking at this seemed to fix issue due to a null datafill on "Speakers Configuration" type setting.

On looking at the "Dell Audio by IDT" control panel, the speaker configuration drop-down menu was set to a null datafill (not sure how this came to be).  I changed the speaker configuration back to "Stereo" and the previous null (ie empty) option disappeared.  Problem appears resolved as all flash audio playback is currently working, and playback is smooth.  I cannot confirm the change actually resolved the issue as the null setting (ie. nothing/blank) has disappeared from the speaker configuration menu.  Reboot of laptop confirmed fix/resolution remained.

I hope this helps.
Comment 70 by Deleted ...@, Aug 1 2012
I forgot to note that when speaker configuration was set to null, all other audio still worked fine.  Only Chrome flash audio was problematic (ie. Explorer could play the Youtube clips fine, VLC Ok etc).

I noticed this sound problem when I play Club Penguin and that started after 21.0.1180.60 was installed. The problem does not exists in Firefox or IE.
I tried setting the default audio format to 44100 Hz (16-bit) and it helped a bit but not completely.

I have audio issues also. The audio has a lot of static sounds when i'm playing videos and I don't have the same problem with IE nor Firefox.  

I'm using Beats audio on my HP pavilion dv6.

Sorry but i have no idea how to patch it. I'm new to this stuff.

Where exactly do i put the audio_util.cc? file.
Comment 92 by Deleted ...@, Aug 4 2012
The one thing is the choppy sound. This has, in spite of all statements of Google, NOT gone away.

But: What is new with Chrome 21.0.1180.60 and Pepper Flash 11.3.31.222 on Windows XP SP3 X86, is the extremely high system load even with SD video. Thus, a Centrino Pentium M 1.50 GHz cannot be used anymore. In this case definitely helps just disabling the plugin pepflashplayer.

It would be nice from Google if they would think of the older stock of notebooks. No one buys a new notebook every year and throws the old one in the trash.

Comment 98 by kareng@google.com, Aug 6 2012
we just pushed a new beta. 21.0.1180.64 the issue should be resolved there. could you please check and let us know?
I just updated to the latest beta and now when I open Chrome no page will load including the start page and any chrome: page. The window loads but the page remains loading and the status bar is blank.
Hi friend! excuse my englis, I'm Stefano from Italy: from 2-5 days I note crackling audio in youtube video in low-definition (240p) in XP and SEVEN system. The problem is only in Chrome (with IE don't exist and sound is ok) and with .flv and .swf in low def.

(more details in "issue 140820")

ubercow13@ could you please add the chrome version? thanks!
21.0.1180.64, just forced an update in response to your request and the problem started immediately on restarting. I have tried disabling my antivirus but it made no difference.

Please download chrome canary and let us know if it shows the same problem: https://tools.google.com/dlpage/chromesxs/

We'll be deploying the changes from the canary channel to stable very soon.
I tried canary but it still has the same not loading problem for me...not sure if it is something else on my system or what! I would rather stay on the beta channel generally though
Seems it's fixed in canary.

I just tried 22.0.1221.0 dev-m and 22.0.1228.2 canary.

22.0.1221.0 choppy sound after 1-2 min. of playback Youtube or Pandora.
22.0.1228.2 no choppy sound during playback of Youtube and Pandora.

Folks, what is your experience with heavily increased system load with Chrome 21.0.1180.60 and Pepper Flash 11.3.31.222 on older Windows machines? On my systems, no siginificant system load occurs with the NPAPI Flash player.
With Pepper Flash 11.3.31.222 I am seeing a CPU load of 50-55% when streaming video in HD.

With the previous NPAPI 11,3,300,268 I am seeing a CPU load of 20-25% when streaming the same video source - this is a significant difference.

Intel Core 2 6300 @ 1.86Ghz
ASUS P5B Deluxe MoBo
2 GB RAM
NVIDIA GeForce 7100 GS
WinXP SP3

I'll be using firefox till this get's fixed. 
I'm getting this problem, even without Flash.  Dominion.isotropic.org plays some sounds when you play a game, but the game doesn't appear to be using Flash.

The issue remains- chrome 21.0.1180.75 and pepper flash 11.3.31.225 do NOT solve it.

To see the issue- go to http://tinychat.com and join some random chat rooms- Notice how you will hear robotic/garbled audio only for some people.

I seemed to have resolved this by disabling this part of the Flash plugin:


Name:	Shockwave Flash
Description:	Shockwave Flash 11.3 r31
Version:	11.3.31.225
Location:	<...>\Chrome\Application\21.0.1180.75\PepperFlash\pepflashplayer.dll
Type:	PPAPI (out-of-process)
 	 Enable
MIME types:	
MIME type	Description	File extensions
application/x-shockwave-flash	Shockwave Flash	
.swf
application/futuresplash	FutureSplash Player	
.spl


FWIW, I'm running Chrome on a Hyper-V VPC.  Win7 x64, with RemoteFX installed.
Any ETA on a fix for this? We are currently advisng users to disable pepper flash however that is obviously not optimal.

Again, going into http://tinychat.com/ttimechat should present the issue if a specific broadcaster is broadcasting with safari or a older version of flash.
tinychathelp: I split off your bug into a more specific one. See issue 142479.
WRT comment #123, Flash still works, even if I disable that single part.
Comment 127 by Deleted ...@, Aug 15 2012
I am also having the same problem as mentioned above (Chrome version 21.0.1180.79 as well as the previous version of 21). Any time I go to any flash based video player, I get this problem, especially playing the video in full screen. I have tested in the latest version of firefox and I do not get that problem. 
Comment 128 by Deleted ...@, Aug 15 2012
Still the same with Chrome 21.0.1180.79 and pepperflash 11.3.31.225 ...
I discovered that, in a two-way RTMPE video chat with Pepper Flash enabled on both ends, echo compensation appeared to be ignored regardless of the "Reduce Echo" checkbox found on the Flash Player Settings > Microphone tab. Both callers could continually hear each other echoed back after some delay. Stats below for one side of the call:

Google Chrome	21.0.1180.79 (m)
OS	Windows 7 or Server 2008 R2 SP1 64 bit
Flash plugin	11.3.31.227 J:\Users\bbishop\AppData\Local\Google\Chrome\Application\21.0.1180.79\PepperFlash\pepflashplayer.dll

Switching back to Flash 11.3.300.271 cleared it right up.

Also, attached is a quick-and-dirty Flash microphone test. We used it to compare the sound quality between Pepper Flash (PPAPI) and non-Pepper Flash (NPAPI):
1) Make sure you have a microphone and speakers
2) Unzip the files to a temp directory
3) Open Chrome and enable Pepper Flash
4) Double-click test_mic.html, click "Allow", speak into the mic and listen to the quality of your voice. I think you'll find that there is very little background noise heard, but you'll get stutters and drop-outs.
5) Now close the Chrome tab containing the microphone test, then disable Pepper Flash and run the mic test again. Your voice should sound more like it's coming from, say, an AM radio station -- more background noise -- but no stutters, no crackles, much smoother.

The point of this exercise is to note that Pepper seems to introduce some new audio signal clean-up process that was a good idea in theory but that doesn't work well yet in practice.

Another note about the test in comment #129: The audible feedback loop is heard more quickly when Pepper Flash is disabled. This probably indicates that Pepper is taking a lot more time to process audio, which introduces latency.

After reading this article: http://blogs.computerworld.com/desktop-apps/20845/explaining-confusion-over-flash-versions I am asking myself: Does anybody know what he is really doing in implementing Flash into something he is working on?
...and another note about comment #129: The simple mic test app does not use the Enhanced Mic API, which to me indicates that the audio issues are not specific to that feature. Hopefully the Chromium developers have already noted this.
Comment 137 by Deleted ...@, Aug 22 2012
Still the the same with Chrome 21.0.1180.83 and Pepper Flash 11.3.31.230. Not possible to use this.
Narrowed down the problem to issues with the Speex codec in Pepper Flash. My development team has also determined that using the Nellymoser codec with a bitrate of 44 khz seems to work well both with PPAPI and NPAPI. We're prepping another test that adds the Enhanced Mic API to this combination and will post results here.
I should say that my dev team confirmed the Google team's findings about Speex. 
Thanks @blakebishop. Do you have a test case that reproduces this consistently?
I will PM you with details.
Update for all interested parties -- we can duplicate the problems when we add Enhanced Mic to our Nellymoser...so we're back to implicating Enhanced Mic in this whole mess.

Not a blocker now, keeping open for feedback going forward.
As soon as I disable pepflashplayer.dll and use NPSWF32_11_3_300_271.dll instead it works perfect. I'm on windows 7 x64 running the chrome beta. This has happened on my desktop and laptop for several versions.

The sites I've noticed it on are the amazon music streaming service and youtube.
version  22.0.1229.79 m
leave only pepperflash and still the same issue, 
if disabled flash wont work
Yes, starting with version 22.0.1229.79, if you disable Pepper Flash, then you have to install your own Adobe Flash Player from http://get.adobe.com/flashplayer
you disable pepper flash, all of them and use the latest flash
download...pepper  flash doesn't work...for me anyway...I just
bookmarked plugins...when it starts happening again I go in and
disable pepper flash again and all is well

(Yes, yes. But it works for me. Or at least it did before Pepper.)
 

Some experiments with Chrome and Hulu...

With PepperFlash 11.4.31.110 enabled:
* Even at the lowest bandwidth setting, audio suffers slight but annoying pops when an application other than the browser runs, like the antivirus. 
* Loading Google News in another tab causes audio stutters and pops even without another major application running. 
* Ads seem to have particularly choppy video (though I'm not too concerned there).

With PepperFlash disabled: 
* Hulu does not play and suggests downloading Flash.

With PepperFlash disabled but NPAPI Flash 11,4,402,265 copied over to the current Google application directory and enabled:
* Simultaneously running antivirus scan and other applications does not cause pops or stutters.
* Loading Google News in another tab does not cause pops or stutters.
* Ads' playback quality is less annoying than ads' content.

With PepperFlash disabled, Flash 11,4,402,265 disabled, and Adobe Flash 11,4,402,287 re-installed:
* (Same results as with Flash 11,4,402,265)


Having to re-install Adobe Flash with every Chrome update is a bit annoying. It's not enough to make videos unwatchable on Chrome, but just annoying enough to make me wonder if another browser would better suit my needs.
Hi,

This is very frustrating. Chrome has introduced numerous bugs, all related to flash video chat. Currently we have the following issues which are all 'breaking' for video chat. Is this googles subtle way of pushing webrtc/hangouts? I cant believe these issues made it through QA and still have not been fixed. Most of these issues appeared on August 1st- Nearly 3 months!

Summarized below is the list of everything currently wrong in the flash video-chat ecosystem. Most are likely related to each other in one way or another.

I also had the same distorted audio with older versions of Chrome, PulseAudio and Linux. YouTube/HTML5 and www-plugins/adobe-flash-11.2.202.243 work without issues.
Hello Chromium,

I would like to second the frustration here. 
Please can we have an explanation on the bugs mentioned here which are still present with PAPI 11.5 and Canary Chrome.
Is WebRTC the only option? That does not work well enbough either.

How can I speak to somebody about these issues?

This issue seems apparent not only on youtube, but ANY flash applications I have come across. Youtube, Vimeo, even small flash games from different parts of the web all have the same static popping.

I use WinXPSP2 and have updated everything there is to update. So please fix it! I dont want to have to switch back to Firefox after all this time.
We're still getting reports of this issue from users on Chrome 23. We're asking users for the following, and will post findings here:
1. Details from your chrome://flash page
2. Sound card type and driver version
3. Audio configuration (sampling rate settings, effects, speaker configuration -- e.g., 5.1, etc.)
4. Sites where the choppy audio issue occurs.

Is there other information that we should also be asking for?

--- 3. Audio configuration ---
No special ALSA configuration (~/.asoundrc is empty). PulseAudio is being used with default settings, too.

I have a 2.1 speaker setup, but the distorted sound was also present with headphones.

--- 4. Sites where the choppy audio issue occurs ---
Tested only YouTube so far.

The media stack underwent a major change in Chrome 23, which is almost certainly the cause of this new spike in reports. Since this bug predates that change, and the issues that it originally referred to are fixed, my suggestion is to close this bug, lock comments on it, and open a new bug to collect reports for the media team.
Labels: Restrict-AddIssueComment-Commit
Status: Fixed
Agreed -- folks please file bugs for any new problems you're encountering.

Using the issue wizard pick "Content" category and choose Yes for "Is it a problem playing back media (e.g., sound or video)?" and provide any details you can.
Created issue 161307 for users who are reporting this issue on Chrome 23 and higher.
