[20.04.1] Problem with my sound... version 2021!

[DLS]

Several full moons ago, I had issues with my sound. Something about ALWAYS having to switch to my prefered soundcard for my sound/volume to work.

I therefore created this thread and had a lot of good answers coming off it:

[19.10] Problem with my sound

Do you only wish to have one device (HDMI/onboard) to output sound? I had issues previously (on 16.04, different computer) and it was due to the power state of the monitor coming up as a different HDMI, so sometimes the sound went off because it was outputting to the wrong output. I'd suggest installing pavucontrol (PulseAudio Volume Control), since you can disable the one you don't use (onboard in my case) [image] If in the case of HDMI, select the correct output. [image] pavucontrol can …

Now the problem I have is practically the same. What changed however was 2 years of development and (at least) 1 full reformat/reinstall. Yet, no progress.

Welcome to January 2021, where I am running 20.04.1-latest and (still!) have both a HDMI and a realtek sound interface but am still wanting to only use one of the two...

So I finally created /etc/modprobe.d/snd-blacklist.conf per what used to work in that previous thread I mentionned and... it doesn't work anymore. Even after I rebooted.

So I ask this great community once again: what does a user needs to do in 2021 for his/her favorite sound card to be stay selected as default after reboot?

Bonus question: what would I need to do for the exact OPPOSITE result on a laptop? (When it boots, it should disable analog and default to hdmi, as it doesn't seem to be wanting to do that either and, because of that very simple need, my mom still refuses to run Linux )

Cheers!
