48 That was the problem! But now I have another issue, because my
49 microphone doesn't seem to want to work in Ekiga ... I can get playback
50 through my speakers (using alsamixer) but no matter what I do I can't
51 get Ekiga's echoing system to echo back my microphone
52 (sip:500@×××××.net) ... It's frustrating at this point in time, but I
53 hope this is as easily solvable as the webcam issue.
