RE: Linn docs surround sound
Yes, this is how I have mine setup.

In Konfig, I reassign the name from HDMI 1, 2, or 3 and call it Apple TV, for the HDMI cable into my EDSM used for the Apple.

Exakt Surround 5.0:
Katalyst Akubariks, AEDSM, AkuKat Exaktbox 6/4200 for 225 Centre, Majik Exaktbox I for 212 Surrounds, OPPO 203 on StillPoints, Cat8
Power: Environmental Potentials 2460, Shunyata Denali, Zitron Cobras, Alpha Digitals
Room Acoustics: SPACE, SubDude HT's, Acoustic Panels

RE: Linn docs surround sound
It is just the doc says you need to have a hdmi repeater or av processor neither of which are necessary

I think you might find that its down mixed to 2 channel. The Apple TV doesn't output processed multi channel PCM and the DSM can not process (decode) the signal.

"The Linn DS/DSM products do not have surround sound software to decode and playback surround sound streams such as Dolby Digital, DTS etc. "

If you run the source signal through an AV processor / AV receiver / Oppo that outputs in PCM (LPCM) via HDMI, then run that to your DSM, you will have decoded/processed multi channel information the DSM can work with.

Akurate ADSM/2
2 channel = Kat Akurate Exaktbox 10, 2X 4200, 1x 2200, Akurate 242's
Surround = 2nd Akurate Exaktbox 10, 1x 5100 for Akurate 225. 1 x 5100 for in-ceiling 104C's. ExaktBox Sub, Sunfire HRS12. Oppo 203.

Just repeating what ropedrag said. You need a repeater or processor for multi-channel audio. Most devices such as Apple TV (and my own Blu-ray) when set to output PCM will down-mix to 2-channel stereo only.

No need for a repeater or processor; Apple TV 4th generation outputs LPCM multichannel over hdmi:

RE: Linn docs surround sound
I know this is an old thread, but just curious to see if anyone else has confirmed the 4th gen ATV will output multi-channel PCM over HDMI as the axc posted. I'm currently running ATV through an Oppo which works fine but is cumbersome for my control app. Thanks to all.

I just last weekend picked up the new gen Apple TV 4K to replace the older generation. Everything I've read and heard indicates that it does send out LPCM, I've not tried it yet as I'm waiting for my new 4K HDMI 2.0 upgrade board for my ADSM/1. But I'm confident it will do what we need.

So until then I'm running it through the Oppo 203 as before however I will add that its vastly superior in all ways to the gen 3 Apple TV, I really like it!

This thing really looks good on our LG OLED, better than everything but a 4K UHD disk spinning in the Oppo 203

Thanks for your reply, glad to hear ATV 4 will work, I plan to switch my cables tomorrow just to see. Just checked and my DSM is already equipped with HDMI 2.0. Looking forward to a better screen!

Cheers.
