Hello Uwe,

thanks for stepping in!

One additional info fromhttps://bugs.launchpad.net/ubuntu/+source/linux/+bug/1612916: NewerWindows drivers do have the same problem .

Regarding binding/unbinding: Yes, it is using snd_hda_intel as well, thecard is even on the same port ( 0000:00:1f.3 ).

1. unbinding/binding on the system works flawlessly, if the system wasnot suspended before.


2. unbinding, suspend, resume, bind does not help,

3. unbinding and binding after resume does not help as well.

I think(!) that it has something to do with the codec. Perhaps missingGPIO or something like that.


Best regards
Michael
