Getting no audio from my AppleTV, after 5.1.1 update.

I too have a problem with no sound on a LG TV when using Apple TV. I have contacted Apple support but they are unable to help me. Is this a compatIbility issue between LG & Apple TV? If so Apple need to address it. Any help anyone can give would be much appreciated.

Not sure if this might work for some of the issues: my son suddenly had turned off our sound and i could not find a setting for the sound.. Finally while playing a tv show i found an option by holding down the select button.. Turned out that the setting was set to play sound over the airport and not the tv.. Selected TV as sound output and all was solved.

I have an LG 42PG60UD. I just bought an appletv3 recently and I had exactly the same issue. I live in Australia.

PROBLEM:
Plugged the appletv directly to TV via HDMI. Video worked well but no sound. I don't have a receiver.

TROUBLESHOOTING:

I tried the following:

1. Changed HDMI cable, even bought an Apple HDMI cable: Still no sound
2. Turned off dolby digital: Still no sound

3. Reset Apple TV to factory default: Still no sound

4. Tried AppleTV on my crappy LCD TV in the back room: (Sound & Video) worked perfectly.

This wasn't a solution for me because I wanted the AppleTV to work on my LG TV at the front. So I went to drastic measures and bought a converter for HDMI to RCA (composite). BIG MISTAKE! DO NOT TRY THIS! because quality was terrible, luckily I was able to return it.

SOLUTION:
I was just about to give up, when I thought I'd play with the settings one more time.

Kept everything as default but changed the Screen Resolution via the settings menu
Audio & Video> TV Resolution> Auto (changed to 1080p 50hz)

Looked like it was picking up 1080p 60hz which my TV didn't like. I don't know how it affects the audio but right after changing that setting the sound worked right away.

SOLVED!!!!!!!! Well for me. I hope this fixes your issues too. Might even solve it for issues with your receiver too.

THANK YOU SO MUCH!! I was going crazy trying everything else and on my LG TV this worked.. Woohoo!

You're very welcome. I had to post my solution as I absolutely couldn't accept why I wasn't getting any sound on my LG TV and because the fix was so simple I had to share.

:)

Wish that solution worked on my LG but I dont have a menu to change the resolution, At this rate I'll have to buy another TV talk about ****** off!!!!

To change the resolution on the AppleTV is generic which means it should be available on all AppleTVs. Sorry my instructions aren't clear but you need to change this setting on the AppleTV and not on your LG TV or any TV.

Can you confirm your changing the setting on the AppleTV?

Well just tried that and its working thanks for the tip woo hoo

Its not working for me.

I recently did an update and the sound was working, I went to use it again just now and there is no sound even when navigating the menu.

Any ideas?

Are you plugged in directly via HDMI or do you go through a receiver?

So the resolution setting on the AppleTV is set to 1080p 50hz?

Have you tried performing a reset on the AppleTV?

Thanks so much....the Auto kept wanting to be 1080p 60hz....changed it to 50hz & voila...it worked...thanks again!
