Below is an email from last year, and this is a followup or at
least related, so I'm including it below for your reference.
Using this USB "sound card" (it's not a card...) I can (as related
below) record input from a tape deckwith Audacity.
But what I haven't figured out how to do, though there must be some
incantation that works, is to simply play audio input coming in via
the USB device, through the speakers. Between Alsa and Pulse, I have
tried every option I can imagine that should make it work, but no go.
Anybody know what settings should be used for sending audio coming
into the system via a USB audio device, to the speakers?
thanks in advance!
