2048 bytes: 16 bits per sample, 1024 samples per buffer.
Does it work better with samplesperbuffer=512 on the audiotestsrc?

In general it's a bad idea to send UDP packets that are bigger than the
MTU, which usually is 1500 bytes (minus UDP header size) or less.


Also try setting the buffer-size property on udpsrc (and maybe the
sink) to some higher value, like 1MB.

They are unrelated to the packet size. The packet size is defined by
the buffer size that goes into udpsink.

Unlikely that it did with the wireshark capture you just sent though.
However if there is no packet loss, it should indeed work :)
