Lost HDMI sound w. i915kms after switching to current

[Mathias Picker]

Hi all,

I’m not quite sure if I should post this here or in -current.

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:~/.config/polybar% 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:~/.config/polybar% 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.

I don’t think I ever saw these “get modes from tunables” messages 
in the logs:
Jan  7 20:02:06 Danton kernel: pcm2: <Intel Kaby Lake (HDMI/DP 
8ch)> at nid 3 on hdaa1
Jan  7 20:02:06 Danton kernel: [drm] Connector HDMI-A-1: get mode 
from tunables:
Jan  7 20:02:06 Danton kernel: [drm]   - kern.vt.fb.modes.HDMI-A-1
Jan  7 20:02:06 Danton kernel: [drm] Connector HDMI-A-2: get mode 
from tunables:
Jan  7 20:02:06 Danton kernel: [drm]   - kern.vt.fb.modes.HDMI-A-2


Any other debugging info needed, just let me know.


Thanks, Mathias
