Audio routing through ATV3 (optical) issue

[LevMac]

Hey guys, I have set my Apple TV 4 Audio to pass through my Apple TV 3 which is connected via an optical cable to my home theatre system.

Problem is, I'm only getting 2 speakers working and no full surround sound. I have made sure that Surround Sound was set to Dolby Digital in Settings, but still don't get my other 3 speakers working.

And yes, the movies I'm watching are all in Dolby Digital, as I tried it on my ATV 3 and got all speaker's working just fine.

Please help!

Does it work from the ATV4 if it's not set up to pass audio through the ATV3?

Sounds like you are doing Airplay, which I thought was only stereo.

I bought this to get around the optical issue.

The new Apple TV 4th Generation has a feature where you can rout your audio through Apple TV 3.
The Apple TV 3 only needs to be connected to power and optical audio to your home theatre system, then through the Settings of Apple TV 4, you can choose "Other speakers" in which your Apple TV 3 should show up on....

I still don't know why only my two speakers are working and not the rest

That's not new, you could do the reverse if you wanted, send audio from the 3 to the 4. the airplay speakers option has been there for quite a while. it would even work on your aTV 2 if you had one.

airplay audio doesn't support 5.1, so you will only get stereo.

if you were airplaying the full video, say from the amazon video app on your phone to the aTV, you should get 5.1 (can't confirm right now, but i think it works)
