-M-audio MidiSport 4x4 USB and M-audio Mobile Duo (USB)
-SuSE 9.0 Pro, (reiserfs) KDE, ALSA CVS from a couple weeks ago, JACK 0.94.0
For some reason the MidiSport always worked and I haven't killed it yet. The Duo audio works too with ALSA driver snd-usb-audio. So there are 2 ALSA devices with the same name... xmms gives me some pops and clicks on a CD but it plays MP3s and .wav's fine. Alsaplayer will play midi files but not CDs. Jack won't connect to anything. Of course I have an on-board Ensoniq AudioPCI to make things worse. -- I just found out I can
=alsamixer -c 1 =
neat tool. If only I had some use for that device.. I only installed it in hopes it would help me trouble-shoot. It has. The 2 USB devices give me 'no mixer elems found' I've read that neither have a hardware audio mixer, so what do I use instead? <--- I think that's the crux of my question. Online doc for .asoundrc was light on examples. I'll surely share my successes.. thanks to Jonathan Rockway and 2004-02-11 16:49.

Here's some console output that someone might get an _aha_ from. It would seem that c 0 is the MIDI controller, c 1 is the on-board, and c 2 is the USB Audio Duo (the one I want to use for RoseGarden, Audacity, whatever..)
