The manual I saw says 24 bits. Bill, you're right, it's 24 bits. I was so happy to hear that Matt's us428 was working that I confused the numbers with the manual in front of me!

The arecord default bitrate is U8 (8kHz, not avaible with my device) so, with the option '-f cd' I've 'forced' (sorry for my bad English language knowledge)alsa to use a bitrate supported (44,1kHz/16bits).

Why not? Thanks. ----------------- Lee, yes, I run: modprobe snd-usb-usx2y nrpacks=1 not sure if this needs 'index=1', too. With jackd I'm in trouble installing the patch.
