Audio with snd_hda(4) works, but only if loaded as a module AND only if I
load the module AFTER booting. If I compile it into the kernel or add
snd_hda_load="YES" to /boot/loader.conf, dmesg shows the following:
hdac0: HDA Codec #0: ATI RS690/780 HDMI
pcm0:<HDA ATI RS690/780 HDMI PCM #0 HDMI> at cad 0 nid 1 on hdac0
hdac1: HDA Codec #0: Realtek ALC885
pcm1:<HDA Realtek ALC885 PCM #0 Analog> at cad 0 nid 1 on hdac1
pcm2:<HDA Realtek ALC885 PCM #1 Analog> at cad 0 nid 1 on hdac1
pcm3:<HDA Realtek ALC885 PCM #2 Digital> at cad 0 nid 1 on hdac1
mixer(8) shows:
Mixer vol is currently set to 75:75
Mixer pcm is currently set to 75:75
There is no audio in that case. Unloading and reloading the module (or
just loading the module manually after the boot process) logs:
hdac0:<ATI SB600 High Definition Audio Controller> mem 0xfe024000-0xfe027fff

pcm2:<HDA Realtek ALC885 PCM #2 Digital> at cad 0 nid 1 on hdac0
pcm3:<HDA ATI RS690/780 HDMI PCM #0 HDMI> at cad 0 nid 1 on hdac1
mixer then shows:
Mixer vol is currently set to 75:75
Mixer pcm is currently set to 75:75
Mixer speaker is currently set to 75:75
Mixer line is currently set to 75:75
Mixer mic is currently set to 0:0
Mixer mix is currently set to 0:0
Mixer rec is currently set to 75:75
Mixer igain is currently set to 0:0
Audio then seems to work fine. (Plugging earphones into the computer's
case's front plugs doesn't do anything, though - audio still comes from
the speakers attached to the plug at the back of the case. Any ideas about
that?) Loading snd_hda from a startup script would probably work, but I
guess that's not the way it was meant to work.
Unfortunately, the recent update to 8-STABLE didn't change anything with
these problems - any ideas, anyone?
Loading driver aftre boot seems have different device probe order. That
causes HDMI HDA codec on video card to be probed either first or second.
It is not snd_hda problem and could be handled just by choosing right
pcm device to use (possibly via hw.snd.default_unit sysctl).
Lack of audio redirection can probably be explained by CODEC
configuration made by BIOS. I suppose that front connectors are
configured as separate pcm device.
