At some point, while using my softphone, my voice was hardly perceptible on the other side. People would hang on me because they could hear only whispers. I could not leave messages because the answering service could not record anything. Very frustrating considering that it was working great before.
Maybe I messed with some configs as I usually do.
I tested the input through my microphone with KRec; it was all as if I my microphone was dying.
I played with the settings on Kmix...
