After upgrading from Kubuntu 20.04 to 20.10 the Device Profile for my Built-In audio is not applying after system restart.  Having not found anything that matched this topic in the bug tracker or forums, I submitted a post (https://forum.kde.org/viewtopic.php?f=17&t=169612) and have not had any hits.

My computer has two Audio controllers.
* Built-in Audio (Profile: Analog Surround 2.1 Output) "This is the set destination of Output"
* GP104 High Definition Audio Controller (Profile: Digital Stereo (HDMI 3) Output) "I don't use the HDMI output"

Sound is produced fine until the computer is restarted. After logging back in the sound either plays via HDMI or shows as disabled (red X in tray) and will not produce sound. The values are still properly set in the Settings panel and to resume normal playback I have to change the Built-in audio to any other value and then back to 2.1. It doesn't happen every restart, but more often than not [update: it does now]. It seems similar to https://forum.kde.org/viewtopic.php?f=309&t=167621&hilit=device+profile, although I don't have a problem with the device not showing. I attempted to reset pulseaudio by following the instruction in that topic, but it didn't seem to have any impact.

Try running pulseaudio -k, then delete the ~/.config/pulse and any pulse related file in the top level of your home dir. This will cause all the sound detection and configs to be recreated. You might have to run pulseaudio -k again after deleting the files.


Thanks for the help!
