I would expect it to be in different places. anyway, the simple solution is to have all line-outs play the first channels(s) when only the first channel(s) would be playing. that could get annoying for people who have multichannel speakers plugged in ... or maybe people would prefer that? so azalia users please let your voice be heard. would you find it annoying when playing *only* mono or stereo to have all outputs play the audio, or would you like that? this would not apply when using more than one dac (more than two channels). otherwise multi-channel/multi-streaming would not work. -- [email protected] SDF Public Access UNIX System - http://sdf.lonestar.org
