ALi M5451 recognized but doesn't play sounds



I'm using OpenBSD 3.7 on a Compaq Presario 900 laptop and the sound device
(ALi M5451) is recognized and configured using the autri(4) driver, but I
don't get any output from the speakers when I do something like:

$ cat /bsd > /dev/audio

or when I try to play an audio CD.

I checked all of the mixerctl settings and played with various combinations,
none of which worked. Here is the output of mixerctl -a:

$ mixerctl -a
outputs.master=255,255
outputs.master.mute=off
outputs.mono=255
outputs.mono.mute=off
outputs.mono.source=mixerout

inputs.aux=191,191
inputs.aux.mute=on
inputs.dac=191,191
inputs.dac.mute=off
record.source=mic
record.volume=255,255
record.volume.mute=off
record.mic=0
record.mic.mute=on
outputs.loudness=on
outputs.spatial=off
outputs.spatial.center=0
outputs.spatial.depth=0
outputs.surround=255,255
outputs.surround.mute=off
outputs.center=255
outputs.center.mute=off
outputs.lfe=255
outputs.lfe.mute=off

I pressed the "increase volume" button on the laptop but I still could not
hear anything.

I know that the sound device is not defective because it works on GNU/Linux.
And there seem to be no irq conflicts with the device either. Here is the
full dmesg:
