Hey, little update.
It is just getting weirder.
Windows continues to have no issues at all with the audio.
I tried a manjaro xfce live usb today and a ubuntu lts live usb today, both only had the dummy output available. Now i boot back into manjaro, and my audio works again. I ran no commands whatsoever.
I can’t loose the feeling it might have to do something with grub, as my second linux sometimes when updating also updates grub and then changes the config. I believe this might have caused the issue in the first place.
Any ideas what to do now? I will leave my machine on standby for now in case there’s some sort of config to export here maybe…
Manjaro uses a hybrid GRUB and most other Linux distributions cannot update it correctly
other distributions are also likely to be using an older version of GRUB
If Manjaro GRUB is over-written it will need to be reinstalled
Manjaro created a script for this (install-grub) recently
Best option is to uninstall GRUB on other Linux OS. if that is not possible, install GRUB on other OS to a different location so it does not over-write Manjaro GRUB
Laptop/Lenovo - ArchWiki shows audio on Lenovo Thinkpad T14 is supported but requires sof-firmware driver (snd_sof_pci_intel_cnl) for the internal digital microphone
It seems like the issue is finally fixed!
I completely removed all grub stuff from the other OS with sudo apt remove grub-common, sudo apt remove grub-legacy and sudo apt remove grub-amd-64-somethingsomething.
I believe this issue is now finally solved, I will respond later if it persistently works or not.
Thanks a lot for all of the help!
edit: Nope, after three more reboots to manjaro it is broken again…
I have no Idea what to do anymore. I just powered up my PC and it works again. The last command I ran before last shutdown was “sudo install-grub”. I feel it must be something to do with grub then?
I also noticed that it appears to not work anymore when it worked after doing a sudo poweroff. sudo reboot seems to not break the audio, neither does suspending break it. It seems like once it works there is some weird difference on what happnes on shutdown or reboot to break it again.
Any Ideas on what might cause this?
edit: When poweroff-ing the machine with working audio, I also caught a glimpse of a message stating something like software reset failed which I don’t recall ever seeing before. Any clues if this might be related?
