20.04 - No sound - only Dummy Output in Settings > Sound

Chris Pollock-2
I posted this last Sat however it's not gotten any replies so possibly
it looked too much like the previous thread about not sound so I've
changed the subject line.

Firstly
Dell Optiplex 780 updated firmware and Bios Gnome desktop. Running Live
Session DVD I have sound in headphones and Settings/Sound shows
'Headphones - Build in Audio'. Under settings/sound on the desktop it
shows 'Output Device - Dummy Output', lspci shows:

00:1b.0 Audio device: Intel Corporation 82801JD/DO (ICH10 Family) HD
Audio Controller (rev 02)

Running alsamixer in terminal, nothing is muted.

I've followed Liams directions here on how to fix the dummy output:

https://www.linuxuprising.com/2018/06/fix-no-sound-dummy-output-issue-in.html

each step in order with a restart in between steps. Even to setting
this
in my /etc/modprobe.d/alsa-base.conf options snd-hda-intel
model=generic when
that didn't work I changed it to auto with still the same effect -
dummy output.

I saw it -- it did get through.

I just got those from Google, I'm afraid. I don't have Ubuntu on a
Dell -- I do run Dell machines for work, but they run openSUSE. Sound
has been fine, but I don't use GNOME -- I use XFCE these days.

I wish I knew anything more, but I don't.

There's a bug here; you might want to subscribe to it and any duplicates.

https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/904347

There is some very old info here:

https://www.linuxquestions.org/questions/linux-hardware-18/problem-with-sound-ubuntu-10-04-64-intel-corporation-82801jd-do-820542/

I doubt it is helpful.

There are plenty more hits.

I just googled the name of your soundcard *in quotes* and "ubuntu". Try it.

"Intel Corporation 82801JD/DO (ICH10 Family) HD Audio Controller (rev
02)" "ubuntu"

Thanks Liam, fixed it! While going through bug
https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/902944 I saw
a reference to Timidity and that it could be using the sound source
instead of pulse. Sure enough running:

sudo fuser -v /dev/snd/*
[sudo] password for chris:
                     USER        PID ACCESS COMMAND
/dev/snd/controlC0:  timidity    944 F.... timidity
/dev/snd/pcmC0D0p:   timidity    944 F...m timidity
/dev/snd/seq:        timidity    944 F.... timidity
/dev/snd/timer:      timidity    944 f.... timidity

Running #killall timidity and then #fuser -v /dev/sound again shows

sudo fuser -v /dev/snd/*
                     USER        PID ACCESS COMMAND
/dev/snd/controlC0:  chris      2736 F.... pulseaudio
/dev/snd/pcmC0D0p:   chris      2736 F...m pulseaudio

Works fantastic - settings shows 'Line Out - Built in Audio'

One more fix I found for blocking timidity from using sound is to
uninstall the timidity-daemon and restart which I'll do here in a few.
If that fixes the issue I can mark this thread as 'Solved'.

Oh, that's great! Glad to be able to help even indirectly.
