Surround Sound Help

Hi there,

Hoping someone might be able to help me please.

Running Jarvis 16.1 on Android TV, Sony Bravia.

I am finding it very difficult to produce 5.1 surround sound when streaming 4K movies from various sources available, when playing the movies it does say they are 5.1.

I have tried various settings, time and time over – made numerous changes and all that I can pass through is stereo.

I’m pretty sure I have made the correct setting changes, when I do play a 5.1 movie enabling pass through etc – all I can hear is a crackling/buzzing noise.

I would be really grateful for any advise, as to what the correct settings are to enable 5.1 sound – thank you.
