Multimedia :: Sound problems with qemu 0.7.2

I'm running qemu via xDSL (the xbox port of DSL) and sound doesn't work. Now i found this post on the qemu forums and it describes my exact problem witha possible fix.
However, since i cant find any config options for sound i then found this thread right here where the 5th post tells me that there is a sound config tool in DSL (sndcardconfog).

The big questions here: could i apply the suggest fix via this tool, and where would i find it?

And feel free to flame. I'm n00b as hell and this is my first attempt at working with linux, so i dont mind.
