Hi,
I just tried out the latest nightly and got problems with the audio playback of E-AC3 files via HDMI on a Rockpro64 (RK3399). If I enable passthrough my AV receiver (Yamaha 477) doesn't recognizes the E-AC3 (Dolby Digital +) stream correctly. I shows PCM. Without passthrough I don't get any sound.
I saw threads for this topic with different HW and also fixes (e.g. Allwinner or RPI4), but they were a few months old.
Does anyone else have this problems and maybe tried out some of the fixes? I can posts log, if needed. But before spending hours googleing I wanted to ask first 
Thanks,
