Thanks, Rodrigo. The way you use the 'multi' plugin to split your incoming 4 channel stream into two 2-channel streams is in principle very similar to what I am doing, so this validates the fact that it *should* work for me. In my approach I create a 4-channel stream by copying the original 2 channels to channels 3 and 4, but after that it is very similar... I have a bit more info to work with at this point. Last night I talked to a person on #alsa IRC channel, who was kind enough to take my config and run it on their 2-card setup. And it worked! Now this is really frustrating. It appears that I have a correct config that just refuses to work on specifically my Audiophile 2496 card. Take a look at the these 'aplay -v' printouts: "aplay -v -Dboth test.wav" on my system. This runs but produces sound only on the nforce card: http://pastebin.com/m480d1b01 "aplay -v -Dboth test.wav" on IRC persons's system. This runs and produces sound on both cards! http://pastebin.com/d4bd6f77c "aplay -v -Daudiophile test.wav" on my system. Runs and produces sound: http://pastebin.com/m5eae7520 I don't see any important differences between the working and not working cases. Could this *possibly* be an ALSA bug that might be fixed by an upgrade? The person from IRC had the latest alsa libs and drivers, whereas I have: Driver version: 1.0.14rc1 Library version: 1.0.13 Utilities version: 1.0.13 Val ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Alsa-user mailing list Alsa-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/alsa-user
