Yeah, I should have been more specific. The issue is with center speaker:
Speakers:
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.
audio/emu10kx:
Setting 'emuctrl mode analog' gave me sound on all (including center)
outputs.
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,
Karol
