Re: Haswell audio no longer working with new Catpt driver (was: sound)

[Christian Labisch]

Hi Lars-Peter,

Additional information to what I've sent you already before :
I found out that sound works with headphones (built-in audio)
But sound still does not work with speakers (built-in-audio).

Christian

Ah, sad.  Can you run 'git bisect' between 5.9 and 5.10 to determine the
commit that caused the problem?


The problem is that one driver was replaced with another driver. git 
bisect wont really help to narrow down why the new driver does not work.


Christian can you run the alsa-info.sh[1] script on your system and send 
back the result?


You say sound is not working, can you clarify that a bit? Is no sound 
card registered? Is it registered but output stays silent?
