Hi,
I'm a similar problem with another HDA Intel.
These are the errors in my case:
[ 7.663820] snd_hda_intel 0000:00:1b.0: enabling device (0000 -> 0002)
[ 7.664648] snd_hda_intel 0000:00:1b.0: irq 42 for MSI/MSI-X
[ 7.723012] intel_rng: FWH not detected
[ 7.766751] hda-intel 0000:00:1b.0: no codecs initialized
If I look for the module I get:
snd_hda_intel 43768 0
snd_hda_codec 100159 1 snd_hda_intel
snd_hwdep 13148 1 snd_hda_codec
snd_pcm 84566 2 snd_hda_codec,snd_hda_intel
snd_timer 26614 1 snd_pcm
snd 61094 5 snd_hwdep,snd_timer,snd_pcm,snd_hda_codec,snd_hda_intel
soundcore 13026 1 snd
And finally I haven't any card:
$ cat /proc/asound/cards
--- no soundcards ---
I've tried with newer kernels but the problem continues:
- 3.15.5-1~exp1
- 3.16~rc5-1~exp1
Information about my card:
