Thanks a lot for the suggestions
I have decided it's not worth the hassle though. I will stick to my WXP box to record audio, since I have all my editing tools like Cubase installed there anyways.
So I will just play the streams in WMplayer and use Freecorder to record them. It's two clicks and I have my 128Bit streams recorded and can simply load them into Cubase with one more click.
Would have been nice to do that on the notebook and under Linux, but .. oh well. I already said in another thread that I am starting to grow grey hairs with some stuff regarding Linux hehe. So why bother when everything works exactly the way I want it to be on my WXP box.
Thanks guys ^.^
