Hi Kalin, Could test team please check whether this can be reproduced ? Thanks!
,
Feb 1 2018
Yes, my team will update the issue tomorrow with any finding.

I am able to reproduce on chell using build R65-10323.11.0 dev Repro Steps: 1) Put volume to 100% -- it's not very evident that the gain decreases if system volume is 50-60% 2) Play youtube video with high volume variance e.g. news 3) After roughly 1 minute, the volume will noticeably decrease w/o user interaction 4) Will not recover unless user logs out and back in I was monitoring cras_test_client --dump_s during this time and it's worth noting that the "System Volume" level never decreased from 100% Additionally, I had cras_monitor running as well, here is the output: server connected output node '6:1: Speaker' volume: 100 <-- Manually verified internal speaker is at 100% num active output streams: 1 <-- Started youtube news video num active output streams: 2 <-- Volume decrease happened at the same time as the # of output streams == 2 num active output streams: 1 num active output streams: 2 num active output streams: 1 num active output streams: 2 num active output streams: 1 num active output streams: 0 <-- Closed youtube Logs here: https://pantheon.corp.google.com/storage/browser/chromiumos-test-logs/bugfiles/cr/802105

avkodipelli@ pointed out issue 769446 looks similar if not the same.
,
Feb 1 2018
Observed issue on 10150.0.0 and 10149.0.0 on chell devices.
,
Feb 2 2018
issue 769446 was on headphone so it should be different. I will try on my chell.

Could not reproduce on R66-10365.0 using youtube. Then strange output stream count might be from notification sound when using shell. Matthew, could you please check whether sox can reproduce this issue ? Since login/logout changes the behavior, it makes me wonder whether it is Chrome changing the volume. Please run: sox -b 16 -r 48000 -c 2 -n -t alsa default synth sine 300 sine 300 This should rule out the possibility of Chrome changing the volume of data. If the issue still happens, I would guess it is from speaker itself. Thanks!

I am unable to reproduce the issue with the sox command you provided on R66-10376.0.0. I ran the command for about 4 minutes and the audio volume remained consistent.
,

Feb 6 2018
Hi Matthew, the audio is consistent when using sox command. This makes the issue more like a Chrome issue. To further identify the root cause, could you also check other boards ? E.g. kevin / bob. If the issue can be reproduced on other boards, then we know this is not specific to chell, and will more likely to be a Chrome issue. Also, could you check whether this is actually a regression between R63 and R64 ? Thanks!
,
Feb 19 2018
Thank you all for taking a look at this. This is a very well known issue for 13 G1 users.
,
Feb 20 2018
Re#14, Hi Matthew, did you have the chance to test on other boards and other versions ? Another point regarding your observation in #6, if you go to chrome://media-internals, in Player tab, and scroll all the way down. You should be able to see where does the second stream come from. Thanks!
,
Feb 20 2018
re#16 This issue does not occur on bob or kevin devices running the latest R65 beta (10323.34.0). As per c#8, the issue is reproducible on R64 (10150.0.0 and 10149.0.0) with chell devices I'm currently checking if there is a regression between R63 and R64, will update with my findings.
,
Feb 20 2018
Thank you Matthew for the update. When issue is reproduced on chell, could you please try other audio sources: 1.youtube or spotify android app 2.sox command. These can help identifying whether the problem is from Chrome or not. Thanks a lot!

I am able to reproduce the issue on both R64 and R63 (10176.72.0, 10032.88.0) playing different youtube news videos. Additionally, the issue *does* now reproduce on a test image (both R64-10176.72.0 and R63-10032.88.0) running the sox command given in c#10: On R64) Issue appears within 3 - 4 seconds On R63) Issue appears within 35 seconds to 1.5 minutes I've uploaded all logs to: https://pantheon.corp.google.com/storage/browser/chromiumos-test-logs/bugfiles/cr/802105 One other interesting observation I noticed (see screenshots in log folder): After recovering the device and logging in for the first time (before doing anything else), I immediately opened crosh and ran cras_test_client --dump_s, which outputs: System Volume (0-100): 100 Capture Gain (-50.00 - 24.00): 20.00dB Cras believes the volume is at 100%. Before I tried to reproduce this issue, I pressed the volume up key to make sure the internal speaker volume is at its maximum setting. However, the volume slider showed the volume level increasing from about 70% up to 100% when pressing the volume up key (F10). Either the volume slider UI or cras_test_client is showing an incorrect value. This only happens on the first boot / login after recovery. Once the volume is increased, subsequent logout/login and reboot attempts do not show this issue.
,

Just checking to see if this issue was ever resolved in future updates from Chrome OS.
,
Jun 11 2018
Sorry, I missed this bug. There were no suspicious message of cras or snd_soc_skl in the logs. Based on the test result in #19, this has nothing to do with Chrome. The stream count variation observed in #6 might be unrelated. Hi Matthew, could you please check again whether this is reproducible on latest chell image ? Please also monitor the stream count by cras_monitor. Thanks! Based on the fact that this only happens on chell, I think this has something to do with Intel DSP. If we can still reproduce the issue, we should create a bug in buganizer and ask Intel to track it down in DSP.

Unfortunately the issue is still present on version 69.0.3497.35/10895.21.0, currently in the beta channel. It is a very annoying bug and it is a shame the issue hasn't been fixed for so long.
,
Sep 16
For what is worth, I noticed listening to 50-60% will sometimes bump the volume to normal audio levels(loud) for half a second and then going back down, again back up and then back down again. Many thanks to those who looked into this problem. Seems like we'll have to accept the issue.

This is a very annoying bug on an otherwise very nice Chromebook. The HP 13 G1. Will this ever be fixed?

Hi bug reporters. Every time you see this issue, please send a feedback report and give us the title of the feedback. Also explain the reproducing steps and rate in the feedback report. Without logs, there is no way to debug the issue. https://support.google.com/chromebook/answer/2982029?hl=en

Hey all, I asked the Chrome OS community on Reddit if this is still an issue and am hearing that this issue is still around on newer versions of Chrome OS. I posted this link if folks would like to submit feedback. |
