my mic - although fully functioning - always records mostly screeching noises, while my voice can only be heard in the background. I have to admit, that I tried different distributions and everywhere there was the same problem - yet some time the mic worked properly. In order to make internet telephoning tolerable for my conversatonal partners, I would like to fix it. I already checked this site and tried a solution adding a line to /etc/modprobe.d/alsa-base.conf, but this didn't work. I have an acer travelmate 5190 with a RV625 Audio Device - I use Ubuntu 11.10 64 bit.
Thx in advance - Ewald
EDIT: The Problem is not with the microphone, the same effects occur with a headset, audio feed can also be ruled out because there was no source of noise during the recording
