Hello everybody,I have an Intel NUC7 that does not have an analog output for audio. Consequently, I have to rely on the output via HDMI. So far, I did not have luck with this. The following audio devices are recognised:
```workstation$ audiocfg list
0: [ ] audio0 @ uaudio0: USB audio
playback: unavailable
record: 1ch, 48000Hz
(-R) slinear_le 16/16, 1ch, { 8000, 11025, 16000, 22050, 32000,
44100, 48000 }
1: [ ] audio1 @ uaudio1: USB audio
playback: unavailable
record: 1ch, 48000Hz
(-R) slinear_le 16/16, 1ch, { 16000 }
(-R) slinear_le 16/16, 1ch, { 24000 }
(-R) slinear_le 16/16, 1ch, { 32000 }
(-R) slinear_le 16/16, 1ch, { 48000 }
```
The two devices detected are USB microphones (webcam and another
microphone). The hdaudio device is missing.
In the kernel log, at least the following is output: ```workstation# grep hd messages
Jul 4 23:23:02 localhost /netbsd: [ 1.0088516] hdaudio0 at pci0 dev 31 function 3: HD Audio Controller Jul 4 23:23:02 localhost /netbsd: [ 1.0088516] hdaudio0: interrupting at msi4 vec 0 Jul 4 23:23:02 localhost /netbsd: [ 1.0088516] hdafg0 at hdaudio0: Intel product 280b Jul 4 23:23:02 localhost /netbsd: [ 1.0088516] hdafg0: DP00 8ch: Digital Out [Jack] Jul 4 23:23:02 localhost /netbsd: [ 1.0088516] hdafg0: 8ch/0ch 48000Hz PCM16*
```I already have a self-built kernel with options HDAUDIO_ENABLE_HDMI in use[1]. However - this option is only documented in HDAUDIO(4) in current. I myself use NetBSD 9.2_STABLE here. Should this also work with it, or is this already my misunderstanding?
Kind regards Matthias[1] https://www.netbsd.org/docs/guide/en/chap-audio.html#chap-audio-hdaudio-hdmi
