Currently Being ModeratedApr 25, 2009 7:06 AM (in response to Stu Sumner)If you haven't tried connecting directly to the TV bypassing the switch try that as not all switches or amps work perfectly with Apple Tv over HDMI.
Are you saying Tv gets it's video/audio via HDMI through an HDMI switch and tehn you use iptical from TV to amp? If so I think you then suggest that audio to TV relayed to amp works ok for 5.1 audio (and maybe 2.0) but not for movie trailers or music trailers. Does it work for music synced or streamed to AppleTV?
Not all TVs can relay HDMI digital audio through their digital outs unless the audio is from the internal tuner, or is in a recognised format. It my be that the TV can relay dolby digital 5.1 but rejects non-surroud audio which typically gets output as linear PCM over optical. I'd check your TV manual - these things are often buried in small print.
Also I woder if the input accepting digital out from TV to amp may be on the wrong setting - could it be set to accept dolby digital but not linear PCM - if the inputhas an Auto setting try that.iMac Core 2 Duo 20", Mac OS X (10.4.11), Intel Macbook, iPhone, old Risc OS and Windows boxes!
Currently Being ModeratedApr 25, 2009 10:29 AM (in response to Alley_Cat)I'll try the first point, but it does seem odd that the switch works with 5.1
The TV routes digital audio out from a Sky HDMI input which is directly connected and both a PS3 and a DVD player which route through the switch in the same way as the ATV. What I haven't tried is connecting the analogue audio outputs on the TV to the corresponding analogue inputs on the Amp. I'm hoping that there is no conflict caused by having both digital and analogue sources routing to the amp at the same time, I'll report back, thanks15" MacBook Pro 2ghz 2gb Ram, Mac OS X (10.5.6), White 16g 3G iPhone, 2009 2Ghz Mac Mini

Currently Being ModeratedApr 26, 2009 10:39 AM (in response to Stu Sumner)Well still no further with this one, but it seems to be an issue with the digital output on the tv. I connected analogue audio cables from the tv to the amp and I get sound but when I use the digital connections I get nothing unless I'm outputting a digital signal like 5.1 DD from a ripped movie. If anybody could have a look at the manuals -

I'd be grateful.
Just as a reminder the TV is connected by digital coax to the DVD input on the amp15" MacBook Pro 2ghz 2gb Ram, Mac OS X (10.5.6), White 16g 3G iPhone, 2009 2Ghz Mac Mini
Currently Being ModeratedApr 26, 2009 12:25 PM (in response to Stu Sumner)I think you need to rule out the switch or HDMI input being the problem.
Try each TV HDMI input with AppleTV connected direct not via the switch. If it works it implies the switch/AppleTV combination is at fault. If one HDMI input works but the other doesn't, it may be they are not quite equal, in which case can you swap over sky and switch connections?iMac Core 2 Duo 20", Mac OS X (10.4.11), Intel Macbook, iPhone, old Risc OS and Windows boxes!
Currently Being ModeratedApr 26, 2009 3:53 PM (in response to Alley_Cat)No change. Directly connected the HDMI lead to the TV and still no sound output through the digital out to the amp. Also tried a different lead with same results (find it hard to think that a faulty lead would output in 5.1 but not just stereo music). This just seems perplexing and niggling, I can just about live with having to press one extra button on my Harmony remote, I'd just rather know what is going wrong with my setup, I've no real interest in changing my setup as I'm space limited although starting from scratch to get rid of all the spaghetti would be a wonderful dream
Edit - even the beeps that you normally expect when skipping through the menus route to the amp, it's just the music that doesn't - very bizarre15" MacBook Pro 2ghz 2gb Ram, Mac OS X (10.5.6), White 16g 3G iPhone, 2009 2Ghz Mac Mini
Currently Being ModeratedApr 26, 2009 3:58 PM (in response to Stu Sumner)You haven't accidentally turned the music volume down (up and down arrows on remote if volume control enabled in settings) - it doesn't work on all things, only music from memory.iMac Core 2 Duo 20", Mac OS X (10.4.11), Intel Macbook, iPhone, old Risc OS and Windows boxes!
Currently Being ModeratedApr 28, 2009 3:09 AM (in response to Stu Sumner)I have exactly the same problem, although I'm using a processor which extracts the HDMI audio directly. HDMI Audio from other sources works as expected, but on selecting AppleTV, it won't always work. Sometimes power cycling the processor or TV helps, which makes me think its some sort of HDCP handshake problem. The only solution was to use a Toslink Optical cable for audio. Glad to know I'm not alone, hopefully this will get fixed with an update.
Currently Being ModeratedApr 28, 2009 3:54 PM (in response to Alley_Cat)Nope, not that either but honestly didn't think it was as the music played perfectly on the amp when directly connected with the optical out. The problem has to be with the way the tv outputs through the digital out, as there is no problem if I use the analogue audio outputs on the tv connected to the amp. As I mentioned above you get all the beeps etc when you're selecting the track to play but as soon as you start listening the amp shows no signal received. As a further check I turned off the Dolby Digital Out option in the ATV menus but had same result - no music over digital out15" MacBook Pro 2ghz 2gb Ram, Mac OS X (10.5.6), White 16g 3G iPhone, 2009 2Ghz Mac Mini
Currently Being ModeratedApr 29, 2009 12:25 PM (in response to Stu Sumner)It's bizarre that you get menu sounds and no music.
One of the TV manual pages says that the digital out can relay Dolby Digital signals - I initially thought this means it only relays dolby digital encoded stuff, but I can't see that menu audio is being sent as dolby digital encoding but you never know. The TV might just be dropping trailer/music audio as it's not in dolby digital format.
It could be an odd configuration issue that might (or might not) be cured by a factory restore of AppleTv but that would wipe all content and settings and require reconfiguration/software updates from scratch - last resort option to try.
I assume that the Tv internal speakers (if it has them) play back music/trailer audio over HDMI (with no analogue connected)? If so, it seems likely the set just isn't forwarding non DD audio bitstreams.iMac Core 2 Duo 20", Mac OS X (10.4.11), Intel Macbook, iPhone, old Risc OS and Windows boxes!
Currently Being ModeratedApr 30, 2009 12:30 AM (in response to Michael Bowyer)same issue with an Arcam solo movie system, returned it to Arcam and they clearly demonstrated that its the Apple TV thats at fault, seems the last ATV update changed the digital output requirements, you now need to overlay two sounds tracks to have this feature, come on Apple play fair stop changing the rules!mini, Mac OS X (10.5.6), airbook
Currently Being ModeratedMay 1, 2009 10:53 PM (in response to Stu Sumner)If your receiver has both HDMI and component inputs and outputs, try passing both audio and video from the ATV to the receiver first, then from the receiver to speakers and TV. This works well for me. I use digital audio and component video from the ATV to the receiver, and component video to the TV. Short runs, excellent signal, no audio-video sync problem. I use the HDMI for the cable box.iMac Core2Duo 20' 2.4, Mac OS X (10.5.6), PowerMac G4 Quicksilver (CPU upgrade); LaCie network drive; Airport Extreme; ATV
