snd_hda weirdness

Tue May 13 21:12:00 UTC 2008

Hi,

I've noticed some strange behaviour with snd_hda.  My fairly new Intel board
has two High Def sound devices onboard.  One 82801I device and an ATI HDMI
device.  The 82801I device uses a Realtek ALC888 codec which snd_hda picks
up fine.  The ATI device uses an unknown codec.

If snd_hda is enabled via loader.conf it assigns the 82801I pcm1 and the ATI
pcm0.  If snd_hda is loaded manually after bootup the pcm unit numbers get
assigned in reverse.

The annoying part is that if snd_hda is enabled via loader.conf the 82801I
(pcm1) is unusable:

# dd if=/dev/urandom of=/dev/dsp1 bs=64 count=100
pcm1:virtual:dsp1.vp0: play interrupt timeout, channel dead
dd: /dev/dsp1: Invalid argument
65+0 records in
64+0 records out
4096 bytes transferred in 5.032943 secs (814 bytes/sec)

The only way to get it working is to load snd_hda manually after bootup.

This is on an Intel DG33BU board.  I suspect this might trip more people up
in future with HDMI adoption becoming popular now.  Any ideas on a fix?

Regards,
Aragon
