Background

Set up new apple 4k tv to Sony 9000E tv last night. The apply TV didnt recognise the HDR on the TV but 4K working just without HDR.

Loaded all my usual apps. Al the apps seemed to work fine but went to watch the new Andy Murray documentary on Prime Video and there was no audio only constant hissing. The trailer for the programme was fine for sound.

I tried a different programme on Prime Video and audio was fine. Appreciate any suggestions as to the cause.

Thought it might be a HDMI cable issue. Would this one be ok for 4K?

Switched out to a belkin HDMI and swapped inputs on the TV so now get 4k but still hissing on the documentary. Tried it on my Samsung in the bedroom and it was fine. Coudl this be an audio codec issue?

Possibly. When you say

do you mean you tried the Apple TV playing the same documentary into a different TV (Samsung) and it worked fine?

No i used the Prime video app on the samsung TV. The trailer works fine on the apple TV just not the full documentary. Bit annoying.

Likely digital bitstreaming/AC3/Atmos vs decoded.

TV will need to know how to handle the audio stream (or adjust the appletv to downmix to 5.1)

Trailers wont be in surround. Try turning atmos etc off and go for a lower grade

Audio format: By default, Apple TV uses the best audio format available. You can change the audio format if you’re experiencing problems with playback. Select Audio Format, then select Change Format and choose either Dolby Atmos, Dolby Digital 5.1 or Stereo.

To get your Sony showing HDR (if it can) you will need to turn on the Enhanched video / HDR setting under HDMI. Otherwise it won't handle the jandle.
