As per the title, rebooting my system after a few days of uptime, I found myself with two “Built-in Audio” instead of the only one included in my laptop (integrated audio card)
lspci -knn|grep -iA2 audio
00:1f.3 Audio device [0403]: Intel Corporation Sunrise Point-LP HD Audio [8086:9d70] (rev 21)
Subsystem: ASUSTeK Computer Inc. Device [1043:1280]
Kernel driver in use: snd_hda_intel
Worst is, my system would default to the non-working sort-of-dummy one (top one in the picture)
By turning it off, I manage to get default audio redirected to the “real” output
This way I would be able to use normally my laptop, if it were not that the Volume Up and Volume Down keys and applet do not affect the audio output through the real sound card.
I took the chance to switch from pulseaudio to pipewire in the process, but the situation is exactly the same with both.
Is there a way to remove this dummy card, or to re-associate the MATE audio widget to the correct one?
Thank you in advance
UPDATE: As suggested by @ricklinux , installing sof-firmware partially did the trick. Now Volume up and down work like a charm, and so does the MATE audio applet.
The dummy card is still listed, but at this point it seems completely innocuous. As per the marked solution, hopefully a fix will be delivered (by chance or intention) for this in some future update
Thank you so much, I was missing sof-firmware!
After installing it, now the Volume up and down work like a charm, and so does the MATE audio applet.
This is the output of the command

If I re-enable the dummy built-in stereo, the Volume up and down gets again associated to it rather than to the real built-in stereo
(in the picture, I am playing some audio as shown in the upper volume visualiser)
