Hi all,
This card works (audio i/o) with the Raspberry PI (Raspbian).
You just need to type 'amixer -c 1 set Mic 80% cap' in a term window to enable to Mic. In PD, under preferences, choose 'Alsa' as output and under 'audio configuration', select 'input Generic AudioUSB Device (hardware) Channels 1' and 'output Generic USB Audio Device (plug-in) Channels 2'.
This is the beast :-) ->
