Description Alex 2018-02-04 20:04:45 UTC

Hi,

I have a PC with Intel Kabylake i3 and 4.15.1 kernel (compiled with "-march=skylake").

"snd_hda_intel" driver is built as a module and have only "HDMI/DP codec support" enabled (it should have Realtek support too, but I don't use MB's onboard sound-card).

The PC outputs sound (PCM, not bitstream) to a soundbar via HDMI.

If I switch on the PC first, and the soundbar second -- I have no sound.
If I switch on the soundbar first -- I have sound.

In both cases I noticed that the driver prints errors in dmesg.
Unfortunately, I don't understand what exactly it says. Playing around kernel options seems not helping. I can only copy-paste the error message here:
