[Alsa-user] I am not duplex

[Don G. <do...@mr...>]

I have a nice old GM synth (a Korg N5) connected to an E-mu 1x1 midi to 
usb connector. Everything in Ubuntu 10.10 can see the E-mu and I tested 
it all on another machine so I know the hardware is alright. But linux 
sound apps see my E-mu as a duplex device, and will connect both inputs 
and outputs to the same side. Usually it connects everything to the 
synth input so I can play midi files thru it but not record from it.

After about an hour of intense clicking between Rosegarden and patchage 
I found that whichever one I connect to first, input or output, the 
other will connect there as well. Only once did it connect correctly and 
I was able to both playback and record. Very frustrating. So how can I 
tell alsa that my E-mu is not duplex and the ins and outs can't all go 
to the same place? I think ubuntu must be auto selecting a module and I 
need to tell it to load the better one.
