(I am not on this list, Please include me on a response) I would like to make multi-channel (at least 4) sound output work. I tried three different cards: Live! 5.1, Audigy SE, and Audigy 4, with the standard FreeBSD 6.0 driver, emu10kx, and OSS. I did not manage to get more than two channels in either combination. Does anyone here have a suggestion as to what would works there? For background, what I am interested in is the recreation of 3D sound environments, like deploying a microphone array in an ecological reserve or other interesting sound environments (see http://hpwren.ucsd.edu/news/050617.html and http://hpwren.ucsd.edu/news/050402.html for examples or preliminary work), and recreating it with fairly standard equipment. For example, once I get the output working, a next question will be how to read from a microphone-quad (or more) while still getting phasing/etc. right. I would appreciate suggestions. Hans-Werner
