It is.

RAOP has a ~2sec latency by design. Anyway, the current pulseaudio sink
does not correctly report this latency. This results in synchronization
problem between player (mpv here) and output stream. This is a known
issue; mpv is not to be blamed here, and your network stack is probably
not either...
