Anyone with experience using the UCA202? I tried it
the other day
using audacity and found that it played and recorded just fine if it
was only doing one or the other. But, if I had existing tracks in
audacity and played those (only 1 stereo) and recorded a 2nd track ...
the recorded track sounded like it was filtered though a motorboat
engine (sputter, sputter ...).
I did the recording again directing the output to an existing device
and all worked fine. So the setup seems to be useable. I am thinking
that audacity (alsa?) can't read+write to the device?
I'm running Ubuntu 12.04. Didn't have jack running.
Perhaps you need to unbind some devices to use the USB device in duplex
mode? USB 1 is AFAIK (I might be mistaken) not very fast, but perhaps it
helps to get rid of other devices sharing the same IRQ.
