MTU %1$u seems to be too low, use "%1$u!" to force.

No matter what i do, i always get that message on sender when i try to send audio (no video).

Why?

cmd line: 'uv -d none -m 192.168.2.243'

Thanks for feedback(s).

Best regards
Jan

Receiver also has some error messsages... seems to be a lil bit tricks.

What i need: Just an Audio stream from Windows PC A to Windows PC B - quality and latency as good as it is possible

Your syntax is wrong. You need to specify a valid value after -m. Such as -m 1400. The way you have it now, you are essentially trying to use the IP address as an MTU value and that is wrong.
