Hello all,to my basic question whether HDMI audio also works in NetBSD 9.2_STABLE, I have received a positive experience report as private mail. Many thanks for that!
As far as my specific problem is concerned, I have to admit that I was far too naive. I should have looked at the PCI vendor and product IDs in the hdaudio driver - the selection of supported Intel chips is very limited and the ID of my chipset is not included:
``` /* Intel */ product INTEL Q57_HDMI 0x0054 Q57 HDMI product INTEL G45_HDMI_1 0x2801 G45 HDMI/1 product INTEL G45_HDMI_2 0x2802 G45 HDMI/2 product INTEL G45_HDMI_3 0x2803 G45 HDMI/3 product INTEL G45_HDMI_4 0x2804 G45 HDMI/4 product INTEL G45_HDMI_FB 0x29fb G45 HDMI/FB ```So it can't work at all, and I'm afraid that adding the ID of my device to the G45 driver is not enough.
For now, I'm going to try a workaround with a USB audio interface and try my luck. If I have misunderstood anything else, please correct me.
Many greetings Matthias On 05.07.21 01:08, Matthias Petermann wrote:
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 messagesJul 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
