This issue is reproducible in Gnawty when following the steps below.


0. Browse to https://webrtc.github.io/samples/src/content/peerconnection/pc1/
1. Open the javascript console (alt+cmd+j or ctr+shift+j) and watch for any errors
2. Press Start
3. Press Call
4. Verify that you see the same video in the local preview (left pane) and remote video (right pane)
5. Verify that you don't see any errors in the javascript console


same issue of muting partially. 

Hi vasanthakumar, could you get the webrtc debug dump like 

https://bugs.chromium.org/p/chromium/issues/detail?id=747450#c7 ?

Also, this might be related to https://bugs.chromium.org/p/chromium/issues/detail?id=797272&desc=5

So, please be sure to test on an image that is late enough on R64 to include the fix

https://bugs.chromium.org/p/chromium/issues/detail?id=797272#c7

Thanks!

Hi I have uploaded the logs and the audio files as requested (with a new folder Gnawty). Kindly have a look.

If you need any help feel free to ask me. 

Logs are available in this link. https://cloud.google.com/console/storage/chromiumos-test-logs/bugfiles/cr/800712/

I uploaded the log to check the waveform.

Hi Peah@
Looks like echo cancellation suppressed it too much.
Could you check if this is related to issue 797272, or a new bug ?


Hi vasanthakumar@
Could you provide the chrome version you tested ?

Thanks!

@ Cychiang: 10176.41.0 / 64.0.3282.79

This issue is reproducible in Snappy device on both the weblinks 

(1. https://webrtc.github.io/samples/src/content/peerconnection/webaudio-input/)
(2. https://webrtc.github.io/samples/src/content/peerconnection/pc1/ )

Logs are attached in the same weblink provided at comment 1.

The same tests performed yesterday with the exactly same Chrome Os and build. It was working just fine. Today I am facing issues. There are possibility for a state bug. 

Partially muting issue seem to be available in Stout device as well. Follow the steps shown in the description of the bug. 

logs are attached in the same link with different folder. 

10176.41.0 / 64.0.3282.79 

In stout same issue while using this link as well.

Hi,
Looking at the aecdumps provided in #1 and #7 I get the feeling that you have both devices in the call in the same room. Is that correct? 

The reason why I think so is that I clearly hear the echo twice in the microphone signal. Or is there anything special in the setup that causes this?

vasanthakumar@: I'm reassigning to the issue to you. Please describe how the setup was for the recording.

Hi@ Peah:

These testcases that I have provided are all performed in only one device and doesn't need two devices to perform. Its like a loop back call scenario. 

There is no special setup required. I used headphones in all scenarios and I have observed this behavior only in few device families and not all chromebooks. Just to avoid maybe headphones are causing this issue. Thus, I have repeated the same test with as many headphones I have. Thus headphones can be ruled out. 

When you make a call using any of the weblink, we should be able to hear our voice clearly. This is the expected behavior. 


Issue is in Minnie, Gnawty, Snappy, Stout as commented above. 

Regarding the voice heard clearly twice: This is the expected behavior if using the weblink in the description. Upon enabling "Add local audio to output" check box, audio of the speaker should enhance a bit. (if noticed well we can hear twice). This is not the issue I meant. We can clearly observe our voice is partially mute while speaking continuously. 


If you need any other assitance feel free to ask me anytime. 

This issue is reproduced in Pyro.

Comment #16, is that really related to this bug?

Vasan, could you retry on a Mac or Windows machine? The test page https://webrtc.github.io/samples/src/content/peerconnection/webaudio-input/ clearly states that Linux (ChromeOS is linux based) is not supported (not sure if that's true anymore though).

Yes thats the same issue of partially muted audio. If following the steps mentioned in comment 16, we can observe the audio issue quite clearly. 

Also I'm not sure what to expect in terms of audio on that test page, it applies a filter "HP filter with fc=1500 Hz" which probably explains why it sounds like this. 

Keep in mind this is a demo page for feeding a media stream into Webaudio and process it using Webaudio effects. 

Also adding local input to the output bypasses the filter hence why it sounds clearer: https://github.com/webrtc/samples/blob/gh-pages/src/content/peerconnection/webaudio-input/js/webaudioextended.js#L34-L41.

I think you can close this bug.

Ok Chris!
