PlexAmp Version#: Android 4.11.5
When I cast, both from web site or android plexamp, to my Onkyo receiver, the music will play for about 10-15 seconds then will be stuck in a noisy 2 seconds loop (Web) or will just freeze (PlexAmp Android).
If I cast to an other device, it work fine.
If I cast to my Onkyo from You Tube Music, it work fine also.
So it seem there is something in Cast from Plex/PlexAmp to Onkyo that is broken.
