I used to use MSN messenger 2 weeks ago and didn't encounter any problem.

As I started again to use it yesterday, the audio channel doesn't work
anymore.

When I proceed the audio tuning, all seems to be fine (microphone and
headphones work on both machines)
Did anyone encounter this problem recently ?
What could be the reason for that ?

If you use Messenger 6.0 and Win XP, go back to Messenger 5.0.
In my case, that helps.
