MSN Video Conference -- Lost audio after several minutes

[stevie.mulia@gmail.com]

Hi,

I have a wierd problem. I can use the MSN video conference with full
sound and video for couple of minutes and all the sudden i can't hear
anything on my PC, not just the MSN conference. The MSN conference is
still on and the video is still working and the other party still able
to listem to my voice, but I can't hear anything on my PC. I tried to
play MP3 using windows media player, winamp and itunes nothing works.

If I close my MSN messenger video conference, my audio starts working
again. I can listen to mp3 and if I open a new MSN messenger video
conference, everything seems to be OK for couple of minutes (after
couple of minutes i can't hear anything on my PC).

My CPU utilization remains 20-30% all the time, the other party can
still listen to me.

I'm running latest MSN messenger v7.5.0322 and the other party is also
using v.7.5.0322.
I've been using this same PC and this logitech webcam for MSN web cam
for a long time. I don't remember when the first time this started but
I think its pretty recent.

I already reboot my PC, un-install MSN (from add/remove program), and
reinstall MSN but still having this problem.

Any body can help me?

Thanks a lot in advance!
