Ok, I see..cheap hardware..

But multiple sources on window$ works..
In this case, windows mixes the sources in software - right?
Is it a big "problem" to do this also in Linux?
This would be an interesting work for me:-)
Perhaps a program as interface between userspace and alsa-driver? Or better directly in the alsa-driver?

Thank you very much!
