Please check in /proc/interrupts whether that interrupt actually works.
There is no interrupt at all being assigned to hda_intel.
Yesterday, all of a sudden, the problem fixed itself and everything about this driver started working as expected. I restarted the driver to be sure and all problems returned. Then I noticed these two lines in the log at the time when the problem fixed itself:
hda-intel: No response from codec, disabling MSI: last cmd=0x20cb2001 hda_intel: azx_get_response timeout, switching to single_cmd mode: last cmd=0x20cb2001
So, I added to my modprobe.conf:
options snd-hda-intel enable_msi=0 single_cmd=1
And now everything works fine and there is an hda_intel line in /proc/interrupts. I don't know what are the implications of these parameters. Particularly single_cmd seems to flag an incorrect operation of the driver. Perhaps the driver should detect and blacklist this card from MSI?
Thank you very much for your help!
