UDP Multicast packet loss and delay

[Frederik 123]

Hi, 

I am using GCDAsyncUdpSocket to send audio from one iOS device to another. To be able to send audio to multiple devices I also use multicast groups.

While the "unicast" audio quality is very high with a low latency the quality is very bad when using multicast. Sometimes I also get a huge delay (e.g. 10 seconds!) until I receive the input audio data.

Do you have any idea how to fix that?
