Audio hiss via headphones

Hi all,

AFTER updating to the latest tvOS13 I noticed there is a much more pronounced audio hiss; it can be heard even more using headphones. You can hear the hiss start and stop when hitting play. The way it use to work prior to TVOS13 is I would hear a slight hiss start/stop after pressing play but then The hiss would stop prior to the movie starting, was beautiful and dead silent. it was perfect. I feel like tvOS13 (latest update) has changed something.

I also have a mediaPC that I use and have confirmed it’s still perfect with zero hiss so have ruled out it being my equipment.

Does anyone else hear this or can the MRMC team look into this? I love your app on aptv4k but the new hiss is really annoying :(

Thanks,
Jeremy

you can try Settings -> System -> Audio output -> Level of inaudible silence

see if any of the other settings make it better on your system

So non of those settings make a difference. However I found out what does - if I change the audio format setting to off and select dd (under Apple settings) it totally goes back to normal with zero hiss. Silly part is I have to reduce the quality to dd5.1 and no atmos to get no hiss. Geez Apple, really?

If I am not wrong, you have the same issue with infuse... I would say The problem is with your denon that firmware might be able to fix.

Possibly, but not in Netflix or any other app. $1500 receiver vs $199 Apple TV....maybe
Audio is perfect coming from mediaPC.

So infuse is fine, you get no hiss there?
