[svlug] How to capture soundcard output to a file?

[Kim]

Hi folks;

I have a few apps that run under wine or vmware that use the soundcard for 
output. None of these apps has the intrinsic ability to route their output to 
a file. Does anyone know how I could capture all the sounds being played by 
the soundcard on the linux host system? Preferably this would be command line 
tool(s) that can be scripted by cron to collect sound samples at regular 
intervals.

If it matters I'm using alsa/Gentoo linux/nforce_audio. Have already tried 
utills like rawrec and commands like cat  /dev/dsp |sox... but just end up 
with files full of silence.

Peace;

Kim
