I’m seeing 5 secs in my system. Room already on so no waiting for amp to start. Apple Music paired to shairbridge. Select a song, song starts gets to 5 secs and then I start hearing it. With that said I don’t have any clipping of the song. So when the sound does start at the 5 sec mark it is the very beginning of the song. Happens if I switch to another song as well. Exact same 5 sec experience. I have a CA10, EA5v2 and a CORE3, Triad Matrix, Triad PAMP, all ubiquiti gear, AC-HD APs.
Delay hasn’t been new for me. I always just assumed it was C4 doing some sort of buffering. Especially since once things do start playing I haven’t missed any of the song.
