[Alsa-user] usb audio -- help needed!

[np <np...@f-...>]

hello list, 

ok, i've almost got my emagic emi 2|6 working after hacking together some of 
the /etc/modules.conf files, but i'm now getting some strange errors when i 
try to play through the device. i'm attempting to use two devices, the 
internal soundcard and the emi. the internal soundcard works, and running pd 
through device 0 works fine. but if i try to run pd through the emi i get a 
lot of strange error messages. if anyone has the time to look through these  
to help diagnose the problem, i would much appreciate it! 

here's the error messages from running pd: 

couldn't open MIDI input device 1
