The driver looks good:

But there is no valid sound card in the pulseaudio, could you please upload the log of pulseaudio.

I am concerned about this:

Jack:
      Installed - Yes (/usr/bin/jackd)
      Running - No

If jackd was already running when pulseaudio tried to start then it might have failed to open the ALSA devices. Please uninstall jackd if you can, and the reboot.

[Hui Wang (hui.wang)]

Yes, #3 sounds sensible. it is worth having a try.

#2 request for Pulseaudio log attached according to following instructions.

[Jere Tuominen (jere-tuominen)]

#3 Jackd log attached.

[Jere Tuominen (jere-tuominen)]

#3 jackd uninstalled and rebooted. Did not help.

sudo apt-get remove jackd
reboot

Can this bug be linked with kernel bugs? Funny that everything was working with Ubuntu 18.04 LTS still.

@Jere,

No,your problem is not same as the ones in the #8.

I need the log of pulseaudio, maybe that will help, to do so:

edit /usr/lib/systemd/user/pulseaudio.service
comment out the line of ExecStart=....
add a new line ExecStart=/usr/bin/pulseaudio -vvvv --log-target=file:/tmp/pulseaudio.txt

reboot

then upload the /tmp/pulseaudio.txt

thx.

[Jere Tuominen (jere-tuominen)]

Tested Ubuntu 20.04 LTS liveCD and the sounds work correctly. System recognizes in the Settings>Sound output devices the following:
"Speakers-Built-in Audio"
"Digital Output (S/PDIF-Built-in Audio)"

[Jere Tuominen (jere-tuominen)]

#9 requested pulseaudio.txt attached.

[Hui Wang (hui.wang)]

According to #11, your usb sound card fails in the pulseaudio, could you please remove the usb and test.

If that doesn't help, I guess you must install some package that conflict with pulseaudio, that can explain #10.

If possible, please collect a pulseaudio.txt without usb sound card.

[Jere Tuominen (jere-tuominen)]

Reply to #12. Lenovo ThinkPad T400 has an internal sound card. So unplugging it sounds a bit challenging.

Removed all the music software installations AND I CAN HEAR MUSIC! CASE SOLVED! Thanks!!

sudo apt-get remove timidity

I guess this affect the result. I remember I met the similar cases before.
