snd_hda mixer problems.

[Adam K Kirchhoff]

I am currently running 9.0-CURRENT from February 24th. I'm having
strange mixer problems with snd_hda. I have two high definition audio
devices on my system, one on the motherboard and one on the HD4850 I have.

[ ***@sorrow - ~ ]: cat /dev/sndstat
FreeBSD Audio Driver (newpcm: 32bit 2009061500/i386)
Installed devices:
pcm0: <HDA ATI R6xx HDMI PCM #0 HDMI> (play)
pcm1: <HDA Sigmatel STAC9220 PCM #0 Analog> (play/rec) default

Since I don't have any HDMI audio speakers, I'm using pcm1 from the
motherboard. And audio plays back fine, and records fine. I have
hw.snd.default_unit set to 1 so that audio applications use that device
by default.

However... I have three mixer devices:

[ ***@sorrow - ~ ]: ls -l /dev/mixer*
crw-rw-rw- 1 root wheel 0, 161 Mar 1 16:39 /dev/mixer
crw-rw-rw- 1 root wheel 0, 88 Mar 1 16:38 /dev/mixer0
crw-rw-rw- 1 root wheel 0, 89 Mar 1 16:38 /dev/mixer1

I have no idea what /dev/mixer is, but it does nothing:

[ ***@sorrow - ~ ]: mixer
mixer: SOUND_MIXER_READ_DEVMASK: Device not configured

/dev/mixer0 is the HDA device on the radeon and /dev/mixer1 is the HDA
device on the motherboard.

So what exactly is /dev/mixer current? And is it at all possible to
have /dev/mixer point to the correct HDA device by default, the way
/dev/dsp does?

Sorry for the needless traffic. Stupid user error. If I'm going to use
the drivers in the FreeBSD base system, it helps if I make sure the
script that loads OSSv4 isn't executable.
