No sound from realtek alc...

[bgroper]

I like to use sound with digital output to external DAC.
It works for some applications, but I'm struggling to get squeezelite working correctly.
This seems good :

root@freebsd-home:/ # cat /dev/sndstat
Installed devices:
pcm0: <NVIDIA (0x0051) (HDMI/DP 8ch)> (play)
pcm1: <NVIDIA (0x0051) (HDMI/DP 8ch)> (play)
pcm2: <Realtek ALC892 (Rear Analog 5.1/2.0)> (play/rec)
pcm3: <Realtek ALC892 (Rear Digital)> (play) default
pcm4: <Realtek ALC892 (Rear Digital)> (play)
No devices installed from userspace.

But this doesn't look good :

root@freebsd-home:/ # dmesg | grep pcm
pcm1: feeder_build_matrix(): can't add feeder_matrix
pcm0: feeder_build_matrix(): can't add feeder_matrix
pcm1: feeder_build_matrix(): can't add feeder_matrix
pcm0: feeder_build_matrix(): can't add feeder_matrix
pcm1: feeder_build_matrix(): can't add feeder_matrix
pcm0: feeder_build_matrix(): can't add feeder_matrix
....

Pls for any help to do this the-right-way.

Realtek ALC strikes again. …

quakerdoomer please, let's not paint an entirely bad picture of FreeBSD support for Realtek audio hardware.

For example, this bug bites only after wake from sleep:

• #6 - Realtek ALC280: AV playback failures following wake from sleep - grahamperrin/freebsd-src - Codeberg.org

Caution: external link.

In /etc/sysctl.conf i have e.g.:

hw.snd.default_unit=4

For you it's probably 2.

Nothing left to paint. Realtek used it's master brush and filled the canvas years ago.

bgroper please, is there still an issue?

I found a possible explanation elsewhere.

Also:

It's remarkable, but maybe not relevant to the digital audio issue; no mention of pcm3.
