I'm just a common user and wondering why I always have to switch the sound settings on my Ubuntu Mate (Release 22.04.5 LTS) after I start my operating system. Is there a way to make the correct output device as a default?
I found some quite same sounding issues in the web but it's too techie for me.
PCM2902 is always as a default but everything is mute with this settings.
I need always switch to 'Family 17th..." but it's not defaulted then. I have always to do the same after restart.
I vaguely remember this a long time ago. It's possible some devices (e.g. a monitor) initialize at different times, and auto switch the setting.
There is a program called pavucontrol ("PulseAudio Volume Control") you could install, which is very identical to the Sound Preferences, but has an option to set a "fallback" which might help.
Not quite the common user way, but it is quick terminal command away to get it:
I did this for a bunch of devices so that I am sure they are never selected (for example, the microphone in my webcam is garbage and I never want to use it).
