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.
I have found with USB audio, I have to find a USB plug that has it's own
IRQ. For example I have:
16: 12488044 0 IO-APIC-fasteoi ehci_hcd:usb1,
uhci_hcd:usb2, i915, ath9k
17: 0 0 IO-APIC-fasteoi uhci_hcd:usb3
That USB2 is the left side plug on my machine, the usb3 is the right... I
only use the one on the right. I also have found I have to unload the
wireless kernel module as it's once a minute scan gives xruns... once
every five seconds if wireless is disabled.
