Muting/unmuting audio issues

[hugegreenbug]

From cugel-383 on reddit:

I was watching a twitch stream, hit super + mute to mute. Hit it again almost immediately afterward, no audio. Open a movie in vlc, no audio. pavucontrol claims that both streams are being pumped out through laptop speakers but they aren't. pavucontrol is set to use speakers by default. Muting and and unmuting the xfce volume control has no effect. The xfce volume control indicator and the popup notification when using media keys don't agree with each other. The indicator claims that it isn't muted by the popup insists it is muted.

This happened to me too. Every time I hit super-mute to mute the audio, hitting super-mute again does not turn the sound back on (though the visuals on the screen appear to show that sound should be playing).

In order to restore sound, I have to open Pulse Audio Volume Control, go to the Output Devices tab, and click the "Mute audio" button next to "Built-in Audio Analog Stereo."

This fixed the mute/unmute for me. There's no need to open up PulseAudio Volume Control.

In the tray, right-click on the volume icon and then select Properties.

Set the sound card to Playback: Built-in Audio Analog Stereo (PulseAudio Mixer). Expand the window if you can't read the entire line.

Close the window and try playing around with audio.

Was having an issue on my gnawty with volume up control. Would turn down with super+F9 but wouldn't turn back up with super+F10, using KennethShen's suggestion fixed it for me.

But instead of choosing Playback: Built-int Audio Analog Stereo, I just picked my sound card and it worked. Mute controls and all.

That symptom also happened on Swanky Baytrail but the recent updates by @ColtonDRG seem to fix all of the prior audio issues including this one.

Wait, what? I suppose it's possible that the new ALSA code from the new kernel we're shipping did fix this issue. I should look more into it.

P.S. I made the baytrail updates, but @hugegreenbug actually made the kernel changes. I just told him where to steal the code from. ;)

The info from @ColtonDRG was in Issue #66:

It's done.... Audio works perfectly on kip. https://youtu.be/CsQrxTrALb4

To achieve the proper switching between headphones and speakers, we stole the entire ALSA system from kernel 4.2.7. The new kernel is here. This should be uploaded to the testing repos soon, but you can download it straight from here if you can't wait. https://cdn.coltondrg.com/linux-image-4.1.14-galliumos_6_amd64.deb
You can remove the old kernel with sudo apt-get remove linux-image-4.1.6-galliumos

And in case you missed it before, the galliumos-baytrail package is here. https://cdn.coltondrg.com/galliumos-baytrail-0.1.1.deb
Again, you can install that and it should remove the old stuff automatically, but just in case it doesn't, you can remove it manually with sudo apt-get remove galliumos-haswell galliumos-broadwell galliumos-device-c710. You may also need to reinstall galliumos-laptop manually after you've done that.

You can install both of these packages with dpkg -i

After installing both of those and rebooting, you should have perfect audio. I won't close the issue until we have more testing results in, but it's hereby fixed!

• @ColtonDRG, issue No sound on Bay Trail (SWANKY, GNAWTY) #66

It appeared to fix it for me. When I was playing around trying to fix the sound issues on my Swanky Baytrail I saw the symptom described above - you either had that happen, or you could do up and down but no mute, and possibly a third weird combo. All of that went away with @ColtonDRG 's changes, whether done on an existing installation or installed new from ISO.

Okay. If you're on any device that's not Bay Trail and want to test this theory further, you can install just the kernel from the above and see if it works. The basic process of that would be as follows.

Download https://cdn.coltondrg.com/linux-image-4.1.14-galliumos_6_amd64.deb
Install with dpkg -i
Remove linux-image-4.1.6-galliumos with sudo apt-get purge linux-image-1.4.6-galliumos
Reboot.

Alternatively, if you're on the dev repos, simply install linux-image-galliumos and remove linux-image-1.4.6-galliumos, then reboot.

gnawty I believe is Baytrail - that is why I reposted the info.

[ghost]

Yes, but this issue applies to all devices.
