the via82xx driver itself supports the multi-channel playback, simply by setting up and passing 4-channel interleaved samples. but, i guess, the problem is the multi-channel output on this codec. there are some vendor-specific registers for multichannel controls on ALC650, but they are still not supported on the alsa driver, mainly due to lack of hardware for tests. i'll let you know if the experimental patch is ready. ciao, Takashi ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Alsa-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-user
