Singstar mic audio mixing

[goxplayer]

I have pcsx2 singstar working really well, mics works well in single player mode or pass the mic mode but when I do battle (where both players sing together) each mic audio is pushed to both players.

I have one mic plugged into my front io and one in the on board audio at the back. It seems that in Windows the audio isn't getting crossed but in game it is any solutions for this?

Is it be possible because they are both plugged into realtek drivers it's causing issues. I'm lost any suggestions would be appreciated .

here are my settings for qemu

You're plugging mics into ONE sound device that's not able to distinguish the difference between inputs because how windows sound works. Get a USB sound card of some sorts to have a different mic source.
