one channel only. in ALSA, low level drivers do not do any kind of format conversion. that is accomplished (if necessary) by code running in user-space, typically part of alsa-lib. the low level driver simply advertises the capabilities of the hardware, provides ways to use those capabilities, and lets the midlevel code and alsa-lib do the rest. --p ------------------------------------------------------- This SF.net email is sponsored by: The Definitive IT and Networking Event.
