Hello, I have noticed sound dropouts on 5.1 content using HDMI Passthrough.
Tronsmart Vega S95 Meta(S905 2GB/8GB) with VidOn XBMC Pro
AVR = Onkyo HT-R391
There is an audio issue causing frequent, brief sound drops(1-2 second duration) with some streamed 5.1 Dolby Digital content within VidOn XBMC. It occurs while using HDMI Passthrough.
The content was streamed from the add-on, HD-Trailers.net. The trailer can be found under Video Add-ons/ HD-Trailers.net/ Most Watched/ Mad Max/ Trailer F4 - 5.1 Audio(hd-trailers.net). It happens on the, "Star Wars: The Force Awakens" 5.1 trailers and others as well. I don't know if it is an add-on issue, VidOn or something else.
Using the program add-on, youtube-dl Control, I downloaded the trailer. The same drops occur when VidOn XBMC plays the downloaded file(mp4). The same file played in the Android MoviePlayer app, does not experience the drops.
