SoC: (Mediatek) MT5893 4xARM Cortex A73 @ 1500Mhz with Mali G71 GPU Android TV (2018 Sony XBR-75Z9F)

The Sony Android TV has a powerful CPU, why does the Android version seem crippled compared to the FireTV 4k stick? The FireTV 4k works very well mostly. It does however play at what appears to be 8 frames per second that is fixed with a skip Fwd or back.

-With surround sound on, 480i channels fail to play unless I skip back once. HD channels seen to play fine but will buffer randomly after some time so the only way for it to wish right is with surround off. The lip sync never gets in sync, is always slightly off.

-One last thing, can you enable DD5.1 Passthrough so it's surround only when the broadcast is 5.1.

Thanks! That's it for now.

Updated OP.

Sounds like there's a bug in the audio driver on that TV's implementation of Android OS. If you submit diagnostics from the app after the issue occurs we can take a look, but these types of issues are hard to debug and we can't go out and buy every single buggy TV on the market for testing.

It's very easy to reproduce. Turn on surround sound and play a non HD channel. Personally I think it's a buffer issue. I will send a log in a few and post here when I do.

Log sent. I went into 2 different 480i channels with surround sound on after a restart of the TV.

Did you get the log? Any comment?

I'm having similar issues with my 2018 Sony TV and have had to disable Surround Sound, which is unfortunate considering that I have a 5.1 speaker setup. Hopefully the Android issues with Surround can be resolved soon.

Even with Surround off, I still get frequent short hitches in the video. Audio is not affected, but the video will freeze for a fraction of a second and then catch up.

These guys don't seem to care honestly. I don't have the same issues with HdHomerun so they can't blame the TV although they like too.....
