Currently Being ModeratedOct 24, 2010 12:51 PM (in response to Shane Scott)what HD content have you tested it with?
is this self converted content? if so then you would need 2 audio tracks.
1st track - AAC Stereo/Dolby PLII
2nd track - AC3 Pass-thru MBP 2.4GHz Mac Mini G4 2 x AppleTV iPhone4 32GB iPod Classic 80GB, Mac OS X (10.6.4)
Currently Being ModeratedOct 24, 2010 12:57 PM (in response to Chenks)I have tried both some HD content from the apple store, direct from the ATV2 as well as accessed within the home network to my macpro. My receiver does not recognize any of the audio streams as encoded as 5.1. I have swapped the audio components around to be sure that my receiver is working correctly and it does respond correctly as recognizes the audio feed as Dolby Digital 5.1 when I swap it for my HD cable box or blueray player.
I can't figure this out!Mac OS X (10.6.4)
Currently Being ModeratedOct 24, 2010 1:00 PM (in response to Shane Scott)OK well not all HD content in the itunes store has a DD5.1 audio track.
can you check in the itunes store if the content from there that you tested actually had a DD5.1 track?
the HD trailers don't have a 5.1 audio track that's for sure, and neither do the previews. MBP 2.4GHz Mac Mini G4 2 x AppleTV iPhone4 32GB iPod Classic 80GB, Mac OS X (10.6.4)
Currently Being ModeratedOct 24, 2010 3:16 PM (in response to Shane Scott)It works for me connected via hdmi to my av amp. I was also able to use handbrake to encode a dvd using apple tv preset and I was able to stream it over my wifi and got 5.1. I have seen some people have more issues with the optical out than the hdmi. I have also seen reports of playing a movie from the itunes store that has 5.1, "they say it under the name of the movie if it does have surround or not. Most trailers don't.
But for me my first test with the atv2 was to rent an hd movie with 5.1 "iron man 2"and it just worked I did not have to do anything to get 5.1 my amp just switched to 5.1 automatically.Mac Pro 8 core 2.8, mac mini hdmi, iPhone 4, Mac OS X (10.6.4)

Currently Being ModeratedNov 12, 2010 8:40 PM (in response to Shane Scott)I had a appletv 1st gen and plugged a 2d gen into the same to slinks and hdmi
I was ticked because library titles I have that played 5.1 on my receiver both through the tv and on the toslink straight to the receiver weren't getting 5.1
The Appletv is plugged by hdmi tot the tv and the tv passes toslink audio to the receiver
Alternatively, the appletv has a direct toslink to the receiver.
Niether was getting 5.1 on titles I got 5.1 on the 1st gen (like my ripped copy of tron from my own DVD)
Well, I managed to fix it by going to Settings> Audio > Dolby Digital and turning it to ON.
The default setting is AUTO. Well, the only think auto about it is 2 channel stereo. It's a deceptive setting. Turn that setting to ON and it forces 5.1 when the movie has a 5.1 track
Worked for me. I hope it does for you too because it's frustrating as he'll that apple would make such a basic option so oblique and turned off.24" 2.16 White iMac, iPad, iPone 4, Mac OS X (10.6.5)
Currently Being ModeratedNov 29, 2010 6:10 PM (in response to Ivan Robertovich)I'll try this because I've been wrestling with the exact same problem since I bought Apple TV 2 last week. A friend of mine has 1st gen and it worked fine on exactly the same cables and hardware so clearly all is not well with the "improved" little black box!! It is really frustrating that such a basic issue is causing so many people (including myself) so many issues.iMac, Mac OS X (10.6.5)
Currently Being ModeratedDec 12, 2010 9:36 PM (in response to Ivan Robertovich)It works perfect for me. It was on "AUTO" and the output was stereo. When I turned it to ON, voilá... 5.1
I tried with "The Expendables (HD)" and "Karate Kid (SD)", works fine with both.Intel, Windows XP
Currently Being ModeratedDec 12, 2010 11:28 PM (in response to Shane Scott)Hi Shane,
If the TV can handle HDMI, why use the optical? Just connect with HDMI which is superior and try the changes suggested above, although auto works fine for both created and purchased content. maybe rest the ATV2 if you haven't. Also as mentioned above...... try testing with HD content that you know has 5.1 sound....... not all iTunes Store HD does.MacPro Dual Quad, Mac OS X (10.6.5), 2TB Raid 5 and 16TB peripheral, iMac, iPad, ATV2, MacBook Pro
Currently Being ModeratedDec 13, 2010 6:32 PM (in response to TheOneAndOnly BiGMaC)Are you saying to hook the ATV directly to the Receiver via HDMI instead of hooking the ATV directly to the TV via HDMI and using an Optical Audio for the Receiver in order to achieve Surround Sound? I'll have roll my sleeves up and spin my receiver around to see what's available back there...MacBook Pro, Mac OS X (10.6.5), Sucky 3G iphone (curse you Steve Jobs!)

Many people use optical to output to their processors/receivers, especially those of us with older but adequate kit, that does not have HDMI - so HDMI to TV, optical to receiver.
If you mean connect to receiver via HDMI, and receiver has HDMI then yes that's a logical thing to do.
Not sure why HDMI should be superior to optical for the same digital audio signal, though with coaxial/toslink audio there were proponents for each type that preferred one over the other.Mac OS X (10.5.8)

Currently Being ModeratedDec 23, 2010 10:18 PM (in response to Ivan Robertovich)This works. However, I noticed that when I don't want to use surround sound and turn off my receiver there is no audio through the TV speakers. Had to turn the setting back to AUTO. Connections setup as follows:
ATV2 -> HDTV via HDMI
ATV2 -> Receiver via Optical
You'd think that the AUTO setting would detect whether to playback to HDTV speakers or HT speakers automatically. Anyone else have this same problem or am I missing something?iPad, iOS 4
