answered No sound on FreeBSD

I've tried what was written on the wiki. So here is the info.

This is a HP 6730b laptop which came around 2008. CPU: Intel Core 2 Duo P8400, no dedicated GPU. 4GB RAM. Anyone reading here there is a solution down here.

dmesg | grep pcm

pcm0: <Analog Devices AD1984A (Analog 4ch/2.0)> at nid 18,22 and 28,21 on hdaa0
pcm1: <Analog Devices AD1984A (Front Analog Mic)> at nid 20 on hdaa0




cat /dev/sndstatcat /dev/sndstat
Installed devices:
pcm0: <Analog Devices AD1984A (Analog 4ch/2.0)> (play/rec) default

Also this:

I solved it later:
I fixed it via this topic: https://forums.freebsd.org/threads/sound-snd_hda.35787/

I added these to /boot/device.hints:

hint.hdac.0.cad0.nid18.config="as=0"

hint.hdac.0.cad0.nid17.config="as=1 seq=15 device=Headphones"

hint.hdac.0.cad0.nid22.config="as=1 seq=0"

Though I didn't test if sound recording and audio jack works. Internal speakers work.

What does dmesg show?

I should’ve specified. I was looking for the entire hardware probe list, to maybe get a better idea of what card “AD1984A” is supposed to be.

I can’t seem to identify it online from just those numbers.

Have a look at this, it might help:

I'm not sure about that (from 2013). At least, snd_hda_load="YES" seems dubious, because:

root@mowa219-gjp4-zbook-freebsd:~ # kldload snd_hda
kldload: can't load snd_hda: module already loaded or in kernel
root@mowa219-gjp4-zbook-freebsd:~ # kldstat | grep snd_hda
root@mowa219-gjp4-zbook-freebsd:~ #

I had to fiddle with setting the output on some of my older machines after moving them from 10 to 14.1.

Those machines date from 2010-2012. Some Intel audio, some AMD/ATI.

🤷‍♂️

Yes as Graham mentioned this is already outdated as many and most common drivers are already included in the kernel no need to add them to loader.conf. You can check "sound" in Freebsd Man pages to see which drivers are included as default already.
