Hello, I've managed to get my Sound Blaster MP3+ USB functioning in part. Playback works nicely and I can capture from the mic input. But I've not been able to capture from the 'LINE-IN' inputs, which is primarily what I'm interested in doing (ooh, so close!).
Is anyone doing this? I'm using the 1.0.3 modules and libs under 2.6.3 and Debian. I've tried the captures with both arecord and ecasound. I'm not sure what the most relevant diagnostics and config are, but to start: # modules stuff ###################################################### alias char-major-116 snd alias char-major-14
