I quite recently got my Vero 4+ and have noticed one issue: Playback of AAC 7.1 or AAC 5.1 video don’t sound that much. I think it is only the surround channel that gets out. There is no problem with AC3 5.1. I have tried to fix it by selecting different audio settings (mostly pass-through) but have not yet found any solution.
My setup is as follows. Vero 4+ connects to HDMI Switch (Chinese noname) and it connects to my Panasonic SA-XR55 receiver.
Output device: HDMI
Number of channels: 7.1
Configuration: Best Match
Passthough: Yes (AC3 & DTS)
With this configuration, should happen with the AAC 7.1? Transcoded to AC3 7.1? Does it matter if the source is H.264 or H.265?
