[Ekiga-list] Bad sound from mic in Windows Ekiga

[Dave Higton]

I've just deleted my Ekiga installation (which came from
ekiga-setup-2.0.9-BETA.exe, and on which I never got more than a buzz
from the microphone) and replaced it from ekiga-setup-2.0.11-BETA.exe.
This is an improvement, i.e. it's not quite as disastrous; I can hear my
voice, though with a bad buzz added, and probably even modulated by the
buzz.  I'm referring to what I hear when I run the audio test in the
installation process.

I can hear other sounds in the headphones OK, so I know that audio out
is working OK.

I have the impression that there's a mismatch in the sampling rates.  I
opted to install with a sample rate of 8000, which wasn't offered in the
list, it had to be a custom sample rate.  I need 8000 as I need to be
compatible with common telecom sample rates.

I think my next step will have to be to feed in a signal from a signal
generator and look at the output with an oscilloscope while running the
test.

OS is Windows XP with a full set of updates.  The sound system is
Realtek AC97 Audio for microphone and playback.

Can anyone suggest what might be done to fix the problem?  Have others
experienced the same?

Dave
