It just shows up as a stereo device in alsamixer instead of mono which is a bit annoying, and you may need to tweak the gain of both channels to get optimal (mono) output. I haven't experimented with it since my computer sounds too much like a leafblower for me to worry about whether the dynamic range is 83 or 96 dB. I really don't know anything about ALSA driver coding, but if someone could get Samson to provide the optimal formula for combining the two gain controls into one it shouldn't be too hard to hack the USB driver to do that. -- Lars Luthman - please encrypt any email sent to me if possible PGP key: http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x04C77E2E Fingerprint: FCA7 C790 19B9 322D EB7A E1B3 4371 4650 04C7 7E2E
