usb headset

Hi, so I am having sound issues with ps2 games only on the ps3, normal, hen and cfw, tried all three, basically whenever I start a game even with the audiolib patch, all ps1, ps3 games work properly, sound leaves on the headset all great but I am not able to do the same with ps2 games, tried...

I've done a bit of searching but so far I've not seen anything. I can wire my headset into my TV/the PS2 but that's a pain because I'd have to stand right up against it. If anyone knows of an app (I'm already running FreeMCBoot) or other tool to enable this, that'd be cool!
