Audio doesn't work on Buster but on Ubuntu

[fenestren]

Hi everybody.

Audio on my pc works without problems with Ubuntu 20.04 LTS.
If I install Debian 10 (GNOME) my audio works just after the first reboot post installation then stops working after the first apt update/upgrade.

Since I strongly need to use Debian 10 can you please help me?

Thank you.

Have you checked in Gnome audio settings that the right source is selected? Also try alsamixer and check the output is not muted. Have you rebooted after the update? Maybe pulseaudio just needs a restart? What does

Code: Select all

$ amixer

say?

Hi!
I reinstalled Debian 10 and, before updating/upgrading everything, I cheched the audio and everything works fine.
Then I repeated the same controls as before (same commands via terminal) and I found these differences (see picture inside the link).

Some entries seem to have appeared under root for pulseaudio.

Did you update logged in as root by any chance?

I have alc892. In this post pulseaudio=PA

In addition to the questions already asked....you appear to have some commands not quite right try

Code: Select all

dpkg -l | grep alsa

# most people need sound out so try
aplay -l

1 It appears you have no HDMI outputs. Did you use pavucontrol to disable HDMI?
2 Which device do you want sound out....and how
eg laptop speakers....would be analog
eg monitor speakers ....most likely hdmi
eg surround sound, using 3.5 mm jacks....would be analog

3) If you are not using PA because you want analog out, its safe to disable PA but do not uninstall it....it makes a mess.

4) But if you want to see a GUI and GUI panel volume applet you may need to re-look at PA I suggest the following
....as FreewheelinFrank has already pointed out....we do this as local user not as root please

Code: Select all

pulseaudio -vvv
# wait.....report any errors....if none
pavucontrol....go to config tab and ensure your analog is not disabled and output tabs for volume level
# alternatively terminal command...should bring up your analog device
alsamixer -c0 

There is more to be done to save mixer levels using alsa...but lets just see if any are muted or too low?

Note that pavucontrol has....inferior icon support to show muted sound....that icon top left hand corner of output devices says "mute"
clicking it....should grey out your volumes levels if NOT muted....and make volumes levels non-grey if they were muted

Hi everybody!
I have the same problem also on another: this time it's a laptop (HP Elitebook).
This time I noticed that the problem occurs at every restart of the machine.
Please have a look on this viewtopic.php?f=6&t=149812
I'm starting to think to a problem into the installation/updating/upgrading procedure...

Thank you so much.
