For example, right now /dev/dsp2 and /dev/dsp3 are playback and capture. Most of you don't have /dev/dsp3 so don't worry about it because it will not work for you. When the CS4231 side of things gets smooth out we will make /dev/dsp0 and /dev/dsp1 access the CS4231 side of the GUS, if there are no technical objections;additionally, if /dev/dsp2 and /dev/dsp3 could then access the GF1 side of things. I doubt that we could improve the sound driver to perform much faster than what it already is. Alain's patch addresses the problem of downloading an incorrect 16 bit stereo sound format stream to the sound card and does not increase the performance of the sound driver. Enjoy, Amancio
