[SOLVED] Pulseaudio only showing "dummy output" device.

arfon · 01-26-2020, 11:41 PM

I just did a 14.2 update (with slackpkg) and after the update, audio quit working. I checked the mixer and only "dummy output" and "dummy input" devices were there.

I logged in as root and ran pavucontrol and it had the normal audio devices...

After some investigating, apparently the update removed my user from all groups except "users". I added my user back to:

Code:

usermod -a -G lp,wheel,floppy,dialout,audio,video,cdrom,plugdev,power,netdev,scanner joeuser

and pulseaudio was fine after that.

Can't believe that is an upgrade issue. I'd bet for a keyboard accident... If you hadn't update for a long time, did you checked the changelog?

Anyway, would you mind marking the thread as solved?

Well, it's a server with an audio notification (ran as joeuser). No one was logged on before, during or after upgrade and the discovery of the loss of audio.

Here's a copy of the history:

Code:

  132  /etc/rc.d/rc.ntpd start
  133  date
  134  date   #Audio was working here for joeuser
  135  pkgtool update
  136  slackpkg update
  137  slackpkg upgrade-all
  138  slackpkg upgrade-all
  139  slackpkg install-new
  140  reboot
  141  reboot
  142  ls /etc/rc.d/  #Audio quit working for joeuser, started investigating.
  143  chmod 755 /etc/rc.d/rc.pulseaudio

The only thing that changed from when the audio worked to when it quit was a system upgrade.

Usual problem would be lack of attention to new config files... Would check what packages were upgraded and which one would have had .new config file.
