[BUG] No Audio in HEVC Videos

Open Gatijog opened this issue 6 months ago • 7 comments

Description: When playing a MKV HEVC 10-bit videos the **conversation of the characters is not audible (no sound) only the sound effects and background music. I tried to increase the volume and yes the sound increases but the conversation of the characters still not audible. I tried playing different videos with different codec and container and the only video affected is the one with H.265 HEVC codec.

The sound works fine for me on a Moto G Power 2024.

I just found the cause of this problem, in the Video Toolbox of HyperOS. It fixed the issue if I turned off Immersive Sound (even if i turned it On again the dialogue still there and didn't disappear but unfortunately lower than if its turned off). Maybe still a bug since other video player dont have a problem with it?

Not a Next Player issue then.

I've just run into this issue on my stock A55 5G.

I did some additional device testing and I believe it has to do with the multi-channel audio. It seems like the software cannot back-process the 5.1 audio into a stereo format and instead just plays the rear left & rear right streams.
