Solved No more HDMI sound on i915kms after going -CURRENT

[mathiasp]

I switched to -current to get the newer i915 driver. Everything but sound works
fine (if slow, see blender post).

Is there something new I need to configure to get sound?
The card is recognized, but there is no sound output:

mathiasp:~% cat /dev/sndstat Installed devices:
pcm0: <Realtek ALC285 (Analog 2.0+HP/2.0)> (play/rec) default
pcm1: <Realtek ALC285 (Right Analog Mic)> (rec)
pcm2: <Intel Kaby Lake (HDMI/DP 8ch)> (play)
pcm3: <USB audio> (rec)
pcm4: <USB audio> (play/rec)
No devices installed from userspace.
mathiasp:~% mixer -f /dev/mixer2
Mixer vol is currently set to 80:80
Mixer pcm is currently set to 80:80

Audio output worked fine on 12-STABLE. I’m really missing it.

This is the hardware
Jan 7 20:02:06 Danton kernel: pcm2: <Intel Kaby Lake (HDMI/DP 8ch)> at nid 3 on
hdaa1

I'm getting quite a lot of these, but if I remember correctly, I had these on -STABLE, too.
Jan 8 19:35:04 Danton kernel: hdacc1: Unexpected unsolicited response with tag 63: ffffffff


Any other debugging info needed, just let me know.


Thanks, Mathias

I have solved this myself, /boot/loader.conf needs to have:

compat.linuxkpi.i915_disable_power_well="0"

With this, the error goes away and I have sound again

Have a nice weekend,
