HDA Intel PCH / Realtek ALC269VB not seen by pulseaudio (whereas alsa see it) after ubuntu 18.10 upgrade

[Alex Garel]

I was using ubuntu 18.04 on my computer (and previously 17.10), and I got the sound card working correctly with pulseaudio.

After upgrading to 18.10, pulseaudio interface only detect my usb microphone (BIRO UM1), but it does not detect my computer internal sound card, either for sinking or as a source.

I only have a "fictive sink".

I have done some experiments: using pacmd, if I try to `load-module module-udev-detect`, nothing happens, and `journalctl --user-unit pulseaudio.service` tells me that the module was already loaded and refuse to load again.
If I use `load-module module-detect` the sound card is detected but does not seems to work correctly !
If I use `load-module module-alsa-sink device=default` and `load-module module-alsa-source device=default` my sound card is seens and works as expected.

So the problem seems with the module-udev-detect not doing its job correctly (or not having necessary rules ?)

Can you please run this command:

  dpkg -l > allpackages.txt

and then attach the resulting file 'allpackages.txt'?

[Alex Garel (alex-garel)]

Here it is !

$ sudo LANG=LC dpkg -l > /tmp/allpackages.txt

[Daniel van Vugt (vanvugt)]

Thanks.

The problem may be timidity (bug 210472) so try removing that.

The problem may also be jackd or jackd2, but based on past experience those may be unsafe to remove. Maybe just make sure they are not running.

[Alex Garel (alex-garel)]

Removing timidity did the job. Thanks.
