NO Sound from the Apple TV unit.

Wow - same thing happened to me. Video is ok from IMAC and IPAD, but no audio. Spent 4 hours on the phone - got pushed between Apple TV and IPAD Senior Tech support for a total cost of $60. Last option offered was restore my Apple TV which I did. No joy, TECH then suggested perhaps the HDMI cable was bad. Since I told him I had watched a video I had downloaded from ITUNES earlier, I thought that was a stretch. I have reset everything - IMAC, ITUNES, APPLE TV, turn off and on repeated..nothing. I hope someone has some ideas here.

Same problem here. Sound from all units worken perfectly before last update from Apple. NO sound at all no matter what I've tride. Have tried switching HDMI input, Changed HDMI cable, changed settings for Apple TV (DOLBY sound off as suggested by many users) .... still no sound at all not even when I'm streaming from other Apple units.

Any suggestions?

Any luck? i have exactly same issue.....ive triend it all...

No sound!!!!! very frustrating

I had a 30 minutes talk with apple support. It all ended in the conclusion that the last automatic update caused the problem. Apple support therefore emailed me a downgrade of the Apple TV software. I have not downgraded the software yet because I need a micro USB to connect to the computer and I don't have that cable yet... So I don't know if it will work.. But I feel confident that it will work since it worked fine before the update. Let you know about the result.

Have now purchased the USB micro cable and connected the Apple TV to my Mac for downgrading the software to 5.0.2. Unfortunately this attempt didn't work as expected. Still no sound. This is really strange because my Apple TV now has the same software version as when I purchased it. It worked perfectly for 14 days. It's an Apple TV generation 3. Next step will be to return it to the store where it was purchased. It really *****. If anyone has experienced the same issue and managed to solve it I would be really happy to know how you did.

Go to the settings > audi &video. Then change the dolby digital to off. I also had the same problem and this fixed this.

Thank you, thank you. Your suggestion worked and I can now finally use my Christmas present!

FINALLY CRACKED THE CODE.....

After many days and days of trouble shooting and contact to Apple Phone Support (who wasn't able to help me out).... I finally managed to google the following result from an apple support link:

http://support.apple.com/kb/TS2090

In my case the problem seemed to be that If the HDMI cable accidently is being removed (or pulled out) while both the TV and the Apple TV is powered on, the Apple TV might stop playing audio which it did in my case.

The following worked for me. disconnect the TV and the Apple TV from the power source (simple power off will not work). Wait for 10 seconds... Then first conntect the TV back to the power source... wait 10 seconds and then connect the Apple TV back to the power source. VOILA!!!

Cheers, Mike

Thanks! The power off worked!

Changing the "dolby digital" to off worked for me too.

I installed apple tv3, but No sound. None of the solutions worked for me. But after 6 hours of trying and 5 HDMI cables later I changed from 1080p 60Hz to 1080p 50Hz in settings and it worked!

Thank you for posting. Turning power off worked for me.

Thank you this also worked for me, after speaking to aplle support for two hours and getting nothung from them i did what you suggested and worked straight away

nice one

Thanks mate - this worked for me!
