[SOLVED] Sound Card ALC888 not detected Debian Buster

[chpaisal]

Hi,

I'll show you my sound hardware configuration:

The card is really an ALC888 but I can't get it to work in Debian 10 (Buster). In Debian 9 it worked well. Since the dist-upgrade the configuration has been lost

root@hp6704:~# lspci | grep -i audio
00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 06)
01:00.1 Audio device: NVIDIA Corporation High Definition Audio Controller (rev a1)

Pulseaudio doesn't seem to detect it, but alsamixer does.

I've tried everything, and there's no way to get the sound back.
What can I do?
Thank you

wiki.debian.org: PulseAudio: Missing playback devices or audio capture

Someone just yesterday was having audio issues with a system they'd upgraded to Buster from Stretch. Couple thoughts about it. Check in your users /home/.config/ a directory named pulse in there, copy that somewhere else ie: somewhere else, name it pulse.bak or whatever. Then try rebooting, seen people mention sometimes these app config directories and files could be automatically recreated if you delete them and there isn't one when you bootup. Don't know if that's the case with Debian Buster though.

Anyway, if still not working after reboot could either remove (or purge) pulseaudio, perhaps alsa-base or alsa or whichever are relevant to your system/OS and then reinstall them or just outright try reinstalling them with ... or similar.

Code: Select all

sudo apt-get install --reinstall pulseaudio

Of course watch the terminal output while undergoing any of the above, what's going to be removed ? Etc.

Finally could resort to what that user ended up doing to restore his sound-audio. He installed Buster completely fresh and sound starting working. Am assuming it was likely a config file conflict as noted above but yeah it did turn out apparently being an improperly done migration from Stretch to Buster that messed up the guys sound. Could get into how you actually performed the dist-upgrade too(not doing that) but unless something has majorly changed weird borkage like this is clearly why fresh installs between releases is the recommended method.

Not works :

Code: Select all

   $ rm -r ~/.config/pulse /tmp/pulse-*
   $ pulseaudio --kill
   $ pulseaudio --start

And not works

Code: Select all

   # apt-get install --reinstall pulseaudio

the only device seems to be the HDMI ports given by the Nvidia graphics card, but I can't hear the audio.

On the other hand, alsamixer detects the motherboard integrated card (ALC888).

How is it possible that pulseaudio does not see a device that if it sees alsamixer? pavucontrol shows all those HDMI devices, but nothing of the analogical output.

By the way, has the alsa-base package disappeared in buster?

And what about this?
wiki.archlinux.org: PulseAudio/Troubleshooting: The only device shown is "dummy output" or newly connected cards are not detected

[chpaisal]

Thanks for the link. I'll try it.

Anyway the pulseaudio automatisms seem to be fine, but when things don't work as they should, it becomes a real nightmare to set up the sound.

It is also curious to see that archlinux has it better documented than debian.

[ruwolf]

In Arch you should set almost everything by hand.
So, they have to have better documentation.

The result is and the problem persists

Code: Select all

$ fuser -v /dev/dsp
$ fuser -v /dev/snd/*
                               USER        PID ACCESS COMMAND
/dev/snd/controlC1:  carles     1983 F.... pulseaudio
/dev/snd/pcmC1D7p:   carles     1983 F...m pulseaudio

The pavucontrol shows many Digital Stereo HDMI 2 Output.

As root:

Code: Select all

# fuser -v /dev/snd/*
                     USER        PID ACCESS COMMAND
/dev/snd/controlC0:  root        856 f.... alsactl
                     timidity   1115 F.... timidity
/dev/snd/controlC1:  carles     1983 F.... pulseaudio
/dev/snd/pcmC0D0p:   timidity   1115 F...m timidity
/dev/snd/seq:        timidity   1115 F.... timidity
/dev/snd/timer:      timidity   1115 f.... timidity

[ruwolf]

Have you tried to close timidity as described in wiki.archlinux.org?

[chpaisal]

YEEEEEEAAAAAAAHHHHH You're crack.

I run this:

# apt purge timidity

after

# alsaximer

OO To enable alsa sound card

Rerun the pavucontrol and YEEEESSS. I can see the "Audio Intern Estereo Analogic"


SOLVED !!!!!! Thanks for all.

I owe you a beer if you ever stop by Barcelona.

Please edit the title in your first post by prefix [SOLVED] so it may help someone else with the same issue.

Thank you!
I had this issue when I upgraded.
