voice problem in video communication

I'm having a problem with voice in a video conversation. When the video
conversation connects, it works fine on the other end. On my end however, I
get no voice. In fact, I get no sound at all (this inlcudes sound from nudges
and winks). The video is fine on both ends and the second party can hear my
voice. If I instead start a voice only conversation, I can hear the other
party fine. I am using MSN Messenger 7.3.0322 (at both ends). I am behind a
D-Link DL-614+ router. The second party is connected directly to a broadband
modem. I am running XP SP2. My box is configured to use UPNP and the router
handles UPNP. I even opened all UDP ports between 5004 and 65535 on the
router. These are supposed to be the ports used by MSN Messenger. This had no
effect. The hardware is working fine. I have gotten Yahoo Messenger to work
(both audio and video). However, MSN Messenger has much better quality. I'd
realy like to get it working. Has anyone seem this before? Thoughts?

I found my problem (there seem to be many different causes). I had my
speakers plugged into the headphone out instead of the line out. A voice only
conversion worked fine but a video conversion didn't. This seems to be
because in a video conversion voice is not handled by MSN Messenger but
rather Windows Messenger. I image this is so a slow or degraded connection
will not effect both audio and video (i.e. your video may clip but at least
you still have audio). MSN Messenger apparently broadcasts to the line out
and headphone out evn if the headphone option is not on. Windows Messenger
does not work this way. It will only broadcast to the headphones if you turn
it on. I hope this helps anyone else that is running into this problem.
