I had a Trident 4DWave card some years ago, and back then it did work with multiopen. I think it's disabled now - I read it in one of the packages documentation. My current GTXP card is much more advanced and supports mixing as well according to the site (I belive most modern soundcards do, only that alsa does not support this feature in all of them). > >Where on the ALSA website, exactly, did you find out your card supported >'Hardware mixing'?
