Hello.
I've been using the M-audio fast track pro USB audio interface for about a
month and I have had a very good experience using it, it worked out of the
box, it's very easy to configure to do basic operation.
But now I want more, I want at least to be able to use the four outs of this
interface.
All four outs are recognized by linux, but they are recognized as different
output devices, and I don't know how to work with both devices at the same
time.
I specially would like to make both devices appear as output devices in
JACK.
If anyone can help me it would be very much appreciated, this audio
interface seems like a very good option to work audio in linux, especially
as it is very portable.
Thank you very much.

Hi,
Please check the user docs on the alsa-project website for the m-audio
quatro. It has two dual channel devices that need to be setup correctly
to be seen as one device.

Hello, thank you very much for the info. I now how to set up it, but I still
can't do it and I don't know what I'm doing wrong.

don't get it recognized in JACK.
If someone can help with this, thank you very much.
