HDMI/DP Audio output on NetBSD

[Dmitrii Postolov <dpostolov%yandex.ru@localhost>]

Hi! Sorry for my bad English...

From the site unitedbsd.com:

Hardware: Intel NUC DN2820FYKH (HDMI), NetBSD 9.99.81 amd64. Note: on FreeBSD all OK with HDMI/DP sound output with Intel drm-fbsd13-kmod video driver.

I am configure and build kernel with:

options HDAUDIOVERBOSE
options HDAUDIO_ENABLE_HDMI
options HDAUDIO_ENABLE_DISPLAYPORT

# mixerctl -a

outputs.master=0,0
outputs.master.mute=off
outputs.dacsel=DP00

# mixerctl -w outputs.master=100

outputs.master: 0,0 -> 0,0	### This is the BUG?

# mixerctl -a

outputs.master=0,0
outputs.master.mute=off
outputs.dacsel=DP00

# cat /dev/urandom > /dev/audio

[Sound play from external Speakers, not from HDMI headphones, pluggeg to ViewSonic Display].

How I can solve the problem with HDMI sound output?

nia@>

audio1 is configured to do 8-channel surround, which might not be what you want - it can be reconfigured to do stereo with audiocfg set, something like audiocfg set 1 p slinear_le 16 2 48000

by RVP request>

# mixerctl -av

outputs.master=0,0 volume delta=256
outputs.master.mute=off [ off on ]
outputs.dacsel=DP00 { DP00 }

Go to stereo (as nia say)

# audiocfg test 1 -> Sound play only from External Speakers, not from HDMI headphones, plugged to ViewSonic Display.
