I'm running Mangler which is native to Linux, not under Wine. I don't have a USB headset. And anyway it should not be necessary to do this kind of stuff. I don't have to buy new hardware when I already have perfectly good hardware to get stuff to work in Windows, so why do I have to do it in Linux? So on Saturday I ordered a copy of 64 bit Windows 7 for my PC. Linux is once again going onto the shelf, so to speak.
