In a Linux system with more than one sound card is it possible to have DOSBox run on the second card? This could be done through alsa (hw1,0) or oss (/dev/dsp1).
try some SDL variable.

I did some quick reading and I found some SDL variables that look right. I tried setting:
SDL_AUDIODRIVER=alsa AUDIODEV=hw:1,0
and
SDL_AUDIODRIVER=dsp AUDIODEV=/dev/dsp1
but neither worked.
However both settings prevented sound output completely and if I spelled out dsp1 or hw:0,0 DOSBox worked as normal so I think this is the right track.
oh geez,
I should have checked my logs. My syslogd was eating 80% of my CPU logging repeated kernel bug messages:

well I see no dosbox there actually.
DOSBox uses SDL to play the audio. All interfaces dosbox has to your soundcard (aside from midi) go through SDL.
