Ah, yes! That was part of what was happening (_now_ I remember). For me multichannel support should include the ability of assigning a mono track (for example) to any combination of outputs in a multichannel bus or track. > This actually suggests a good trick for my base-setup.

What performance problems have you seen? Having jack manage the sound card should not affect performance, actually probably the reverse will happen if you use ALSA directly, unless the programmer of the application in question has a very good knowledge of ALSA. That is part of the beauty of jack, you don't need to know anything about the gory details of the ALSA api. -- Fernando _______________________________________________ music mailing list music@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/music
