CRAS: device is not running but server thinks it is running

The symptom is no sound played to headphone.

I checked the log and found that alsa device was not playing.
However, the state variable maintained in cras thought device was playing.
So, cras kept sending samples to device, and samples kept accumulated in the device buffer.
I checked the code path but could not figure out how this can happen.
There was a suspend/resume in the log.
Not sure if suspend/resume might cause this.

Hi Kalin, have you ever noticed this kind of issue ?
Could QA try to reproduce this issue on kevin?

Thanks!

We have not observed such outcome, but we usually do not do long term testing.

Feedback note:
Listening to Google Play, closed Kevin without sleep/locking.  Headphones still in jack & attached to my head.  I think I reopened it once en route to a building and it was fine (music played in headphones) but now there's no sound.


Sridhar,
lets have a Kevin device on the following scenario:
1) Plug headphones
2) Open few browser tabs, with one of them streaming music
3) After some time, close the lid(suspend should happen)
4) After some time open the lid. Check for audio playing on headphones and close the lid again(suspend should happen)
5) After some time open the lid again. Check for the audio. Is it missing.

'some time' could be like short(e.g. 10 sec) or longer(e.g. 5-to-10 min) period of time
