Now that I think about it, the changes I picked up from -current included checking for a microphone, and dealing with it if it was there. So yeah, that would explain it. However, it still seems to sample at 48K, even though I'm telling it to sample at 44.1K. I may try the patch you pointed me at along with my changes to -stable, just to see if that works better. I don't expect it to, though. Thanx, http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
