Hello,
I have a rather recent laptop, a Dell Latitude 9520. I had no sound in the beginning but this was due to a bug in sof-firmware. With a 5.15 kernel I now have a working audio output. You can see the relevant thread here.
However a recent update made my mic not working anymore. As I don’t use it on a weekly basis, I cannot precisely pinpoint the date but I think it was in the past couple of weeks.
What can I do to try and solve this issue?
Here is the output of inxi --admin --verbosity=7 --filter --width
