Since the machine is Kabylake and the codec chip is event unknown one, your device is likely too new and not supported even by the upstream. The symptom implies that some power-related stuff, and there can be a missing sequence to power up the controllers properly. The alsa-info.sh output you attached already shows that the read from the codec chips failed for both the Conexant chip and the HDMI on i915 graphics. -- You are receiving this mail because: You are on the CC list for the bug.

So it's something missing in 4.4.x backports. I'm building a test kernel with a few possible fix patches. Could you try the kernel in OBS home:tiwai:bnc1048356 repo? It'll take some time (an hour or so), and will appear at http://download.opensuse.org/repositories/home:/tiwai:/bnc1048356/standard/ -- You are receiving this mail because: You are on the CC list for the bug.

Now looking at the previous alsa-info.sh output closely, the error messages are related rather with i915 HDMI/DP codec. Maybe that screws up the whole, including the analog codec once after it happens. Could you try to pass probe_mask=0x01 option to snd-hda-intel module? e.g. create a file /etc/modprobe.d/90-hda.conf containing the line options snd-hda-intel probe_mask=0x01 This will enable only the first codec, so the likely problematic HDMI/DP audio is disabled. -- You are receiving this mail because: You are on the CC list for the bug.

Yes, that has fixed the audio problem. I can now switch to standby and not lose sound from the internal card.

Then it's confirmed that the issue is in i915 side. Let me check more...

I did it with the patched kernel you had sent me (4.4.75-2.ga675a97-default), because opensuse only keeps two kernels at a time.

You can increase the number of kernels to keep by editing /etc/zypp/zypp.conf. Change multiversion.kernels line, and put more, e.g. last-2, last-3, etc. -- You are receiving this mail because: You are on the CC list for the bug.
