Ubuntu buil 0.5.5-65 Audio stopped output

[nicole.f]

Hi,
it is a pretty weird, but the audio output of my Pinebook 11.6" stopped working - but is still working in Android.

I have Android (from factory) on eMMC and Ubuntu with Mate desktop build 0.5.5-65 on microSD card. I used it to watch Youtube videos including audio using SMplayer. It worked nicely all night, using the speakers and using headphones.

Next day I resumed the device and every since I can not hear anything from the device, neither speaker not headphones. I checked the mixer and Pulse audio settings and can not find anything suspicious - though I have to admit that alsamixer exposes way too many mixers. Most of them I can not tell their function.

I also compared the default /usr/share/alsa/alsa.conf with the one on the device in order to find any mixer misconfig, but they are identical.

Currently all audio playback seems to run fine, all players play as expected but there is no audible output.

If I reboot into Android again everything seems to be normal.

Any idea?

Thanks!

Cheers

Hi I think that is already fixed in the latest Ubuntu Mate images (script restores mixer settings after suspend), you can upgrade to ayufan's latest release like described here:

https://github.com/ayufan-pine64/linux-build/releases

If you loose your audio settings for some reason you can also get the original asound.state file from his repo at:

https://github.com/ayufan-pine64/linux-b...r/lib/alsa

Put that back into /var/lib/alsa and call alsactrl restore

Edit: Yes the mixer has a lot of settings exposed, that is because the audiocodec combines three interfaces into one and has a lot of paths, if you want to know more look at the usermanual for the A64 in the wiki.

   

The critical volume controls are AIF1 DAC timeslot 0 volume = ca. 65, DAC Volume = ca. 60 and Speaker Volume ca. 80-90 for the internal speakers.

Thanks a lot! That did the trick - I used the asound.state from the GIT repo. My mistake was that I did not recognize that the state is saved in /var/lib/alsa/... I just looked at /usr/lib/alsa/ : Every distro has its specials...

Thanks again!
