No audio in MSN Messenger

[Guest]

When I first installed Messenger 6.2, I had no audio, although my speakers
and microphone work in every other application, including other instant
messaging apps. One day, for no apparent reason, the audio started working.
It worked for a couple of weeks and now no sound again (either in or out).
According to the Audio/Video Wizard, it should be working. I have already
tried uninstalling and reinstalling MSN. I am connecting through a router
and using a firewall, but have tried bypassing the router and temporarily
disabling my firewall and even my virus protection. Can anyone help?

Sound need uPnP NAT FW.
If you are running Windows XP with SP2 turn on the uPnP check in the
exception tab of the WFW. (also check MSN Messenger and Messenger checked
would not hurt)

If running a 3rd party FW you must open addition ports for Messenger or MSN
Messenger.
I think 1900 is the uPnP port
OUT 1860 tcp,1863 tcp , 6891-6900 tcp and other UDP ports
IN 1860 tcp
Search the google for ports , MSN Messenger online help, etc
Different ports allow additional MSN Messenger functions.
