Hi Jim,

Could you expand on what you mean by "loading the audio module with the correct option"? I also just moved onto a machine with the same problem.

I had to do a lot of fiddling around until I could get the microphone to work. Once it worked in MS Sound Recorder, I figured all my problems were solved, but then depending on which SIP phone I used, my callers would either hear clear audio, or clipped, tinny audio. I don't know any further tweaks I can make to fix this - and by the way I am testing on a LAN within my office, so I'm pretty sure this is not a networking issue.

have you tested audio input with any other programs?
That is, have you tried Skype's echo service to see if Skype works
with your sound card?  Or have you tried arecord and aplay to see how
things work?

I mention this because I have a laptop whose audio output worked fine,
but whose input was terrible until I started loading the audio module
with the correct option.

Good luck.
