Very interested !
Just been wresting with Audacity under Ubuntu Studio with a lot of problems, even with the CPU's set for Performance I'm still getting a lot of lag and stuttering.
I've gone back to Cooledit which does run under OS/2-Win, obviously under OS/2.
I tried Audacity under Windows with a SB Audigy card and had no end of problems with getting the input to switch between Line and Mic, that card is simply a no go under Ubuntu but it works fine apart from mixer options under OS/2.
It would be so nice to have Audacity running under OS/2. Happy to leave Hydrogen and my synth's running under Ubuntu, and do all the final mixing and converting, writing under OS/2.
