Hello, Ryan! RCG> nto: Added int32/float32 ... isn't this just ALSA? Why's it a seperate RCG> backend? Because it is a QSSL's implementation of the ALSA API. It have nothing common with ALSA 0.5.x except for API. It even doesn't fully compatible with ALSA 0.5.2, on which API was based. With best regards, Mike Gorchak. E-mail: lestat at i.com.ua
