Dear list, I am happy to join this mailing list hoping to learn a lot about the ALSA its functionality. I am working on an old Lenovo X1 carbon with an HDA Intel hardware running Debian testing with a linux kernel 5.16.0-6-rt-amd64. I have been working with Debian for quite a while, but since my last upgrade I am having issues with sound in my system (the classic “Dummy Output”).. Since I was getting no result on trying to fix Pipewire/Wireplumber or Pulseaudio, I decided to wipe my system and just install (from apt) the following ALSA packages: libasound2 1.2.8-1+b1 libasound2-plugins 1.2.7.1-1 alsa-utils 1.2.8-1 …and I am already having some problems. First of all, I can list all my audio devices with play -lL and record -lL, so all the drivers should be in place (I guess). Opening alsamixer shows the card HDA Intel PCH (chip RealTek ALC3232) and I can set all the levels as I want. Playback and recording works as expected, but the list in the F6 menu is empty only "(default)" and "enter device name…" are listed, and I remember that I could switch between the integrated Realtek device and the HDMI output. So I started to look around and check the ALSA services but: sudo alsactl restore returns a symbol lookup error: undefined symbol snd_ctl_elem_id_compare_set version ALSA_0.9 And so do the services: sudo systemctl status alsa-state.service sudo systemctl status alsa-restore.service They are both deactivated, and, as expected, everytime I reboot the laptop, I have to manually restore the mixer settings I am not sure whether the two problems (the empty list in alsamixer and the symbol lookup error) are related, but I would really appreciate if you could guide me through a possible debugging path. Thank you very much in advance for your help.
