IMHO. I choosed to send the sound to one channel only, so the apps can use all 8 mono channels. Since most cards can do mono to stereo in hardware, I would be nice to add a capability flag for that. Using that features you halve memory usage for buffers and irq frequency. Bye. --- This SF.net email is sponsored by: The Definitive IT and Networking Event. Be There!

[Alsa-devel] audigy2 strange behaviour
