After upgrading from Ubuntu 18 to 20 pulseaudio starts with HDMI output disabled and doesn't turn on when I turn on the TV

[Jaromír Cápík]

Before the upgrade the HDMI 4 digital stereo output was chosen automatically for my nvidia GF card and was usable by the players immediately after turning the TV on. After the upgrade I have to switch the profile from Disabled to HDMI4 each time I turn the TV on. It doesn't get stored properly.

I just studied the PulseAudio 13 release notes and it is probably related to the following "improvement" ...

::Automatically switch away from unavailable card profiles::

How about restoring the profile when it becomes available again?

[Jaromír Cápík (tavvva)]

I had a talk with the upstream on #pulseaudio IRC channel and the issue has not been resolved upstream yet. The guys expect the fix before the PA 14 release.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please execute the following command only once, as it will automatically gather debugging information, in a terminal:

apport-collect 1905080

When reporting bugs in the future please use apport by using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs.

Hello. Like mentioned in #1905078, I don't have the apport package installed and don't plan to do so due to various reasons. Right now I'm working with PA downgraded from 1:13.99.1-1ubuntu3.7 to 1:11.1-1ubuntu7.10 that doesn't exhibit such problems.

[Jaromír Cápík (tavvva)]

I started some investigation with the pulseaudio upstream and the issue is caused by the fact only the currently selected profile receives updates of the the plugged/available state since PA13 and that conflicts with the feature of switching the unavailable profiles away. They never get back from the Off state.

[Daniel van Vugt (vanvugt)]

Reassigning to the kernel since the upstream PulseAudio bug was closed as such.

[Daniel van Vugt (vanvugt)]

Also in the least we need to know the OS version you are using and the hardware/driver. So please run:

  lspci -kv > lspci.txt

and attach the resulting text file here.

[Daniel van Vugt (vanvugt)]

Thanks but we still need more information:

What version of Ubuntu are you using?

What version of the Nvidia driver are you using?

[Daniel van Vugt (vanvugt)]

Nevermind, it seems we already have bug 1745866 for this.
