Yeah, I should have been more specific. The issue is with center speaker:


I'm using a 5.1 analog speakers setup, which is connected to all 3
outputs of Audigy. There are 3 cables between amplifier and Audigy, one
responsible for front speakers (l/r), one for rear speakers (l/r) and
last one connected to 'digital output' is used by center/subwoofer.

Sound is coming from player (stereo) to /dev/dsp.


Setting 'emuctrl mode analog' gave me sound on all (including center)
With 'emuctrl set outX' I could control volume on front/rear/center.
In 'digital mode' I got noise from center speaker.

snd_emu10kx on CURRENT:

By default I get sound from 4 speakers - front and rear.
From center I get noise.

I realize this setup has nothing to do with 5.1 sound but it's better to
play music on 4 speakers, and sometimes the center one is useful too :)
I hope this clarifies the issue. Thanks,
