Sound on Apple TV not working.

I hate to say this answer, but my Apple TV does the same thing randomly from time to time. It's super frustrating. I went to the settings in the Apple TV and chose restart (not just unplug it and plug back in) and so far it's been the temporary solution that works.

This isn't necessarily an AppleTV problem if you are connecting your AppleTV to your receiver.

The issue is the EDID that's being sent over HDMI from your display. Checkout this article and see if it correlates with the problem you're experiencing. It will also give you the solution you're looking for:

One thing is for sure that I will not be buying any chinese HDMI-doctors or HDMI-switches or junk like that.

I don´t believe the problem is between ATV and receiver.

How come the same stream-sources with iPad & iPhone work out just fine..?!?! How come rebooting your laptop solves HDMI-problems?

Well. Here we go again. Sound is missing.

I will not discuss anymore about HDMI and the cables.

Receiver and the cabels are fine. Laptop is the problem.

I just spoke to my friend, who is a "Certified Apple-guy". He agreed with me. Talk about receiver, cabels, EDID or whatever is stupid and unnecessary, because there is proof that the systems works. (iPad & iPhone). What I should do is wait for a software-update for my Retina-Macbook.

Hey, I am also experiencing this issue.

Randomly i cannot get any sound out of my Macbook Pro when Mirroring to my ATV 3.

However, sound will work fine when using itunes airplay function. But when i use the airplay function to Mirror any other program (quicktime/youtube etc) i only get picture and no sound.

When i go to sound in system preferences it will not let me select Apple TV as the output.

I have the ATV 3 hooked up to my Pioneer VSX-921 reciever using HDMI cable.

The only way i can get the sound back is to restart my Macbook, which is highly annoying.

Thoughts?

Thanks for your help...

Dear 75mCoops. Can you please post the model of your TV and if you can remember, what year you purchased it? That will be helpful. Your receiver is HDMI 1.4 and I'm wondering if your TV is also 1.4 or simply a 1.3b or 1.3c TV.

Secondly, when the audio drops out, what does your pioneer show for an audio signal? Normally, if there is a stereo or dolby, the front face of the receiver should be showing you the input signal of the audio.

Thirdly, I know that you've indicated that rebooting your Macbook works. Does it also work if you leave your Macbook alone but reboot your AppleTV? I'm very interested in finding out more about these minor detail points. Sometimes we do one thing (like reboot the Macbook) and we think aha! That's it.

However, you may also find that turning off your TV for 10 seconds also works. You may also find that unplugging the HDMI cable from your TV for 10 seconds and then re-plugging it in also works. Understanding those nuances are reallly important as the issue again may be HDMI-handshake related and not Apple AirPlay-related. Unfortunately, HDMI requires a digital handshake to initiate copy protection and it may be (I'm not 100% sure and that's why I'm asking) that when you stream a device via Airplay additional information is sent from the originating device into the HDMI chain.

My strong suggestion (annoying as it is) is to do some of these additional micro-steps of detective work. The symptoms being described are more akin to HDMI-related issues than anything else in my experience, but you can only validate it by getting some of this additional info.

If you could re-post, that would be great and I'd be happy to do some parallel debugging on my end.

I have bought an Apple TV for the Airplay function mainly and I have used it for the 2nd time today.

When I booted up the sound was coming from the macbook instead of the TV so I unplugged the ATV, rebooted and hey presto the sound was coming from the TV.

About an hour later the sound dropped out completely from the tv. I tried disconnecting from the TV and the sound came back to the macbook. I reconnected to the TV via airplay and the sound was neither on the macbook nor the TV.

I tried restarting all but the macbook and in all honesty if that is the solution then that is not good enough really. It's 2014 and this is an Apple product which means it's not the cheapest and I expect it to work properly. That is what makes Apple products appeal to me. They work. So why are we expected to unplug/reboot etc all the time?

All the while, if I use my iPhone or iPad the sound works fine.

All softwares are up to date and I have tried numerous HDMI cables and th result is the same every time.

Same thing for me. I restarted the Apple TV and the sound was back but then the picture was gone. Unplugged the Apple TV as others had noted and now it's working. But for how long?

I had to do all this yesterday as nothing would stream without constantly stopping though sound would continue.

I didn't think anything about it until sound gone this am.

Good thing I have a roku in my bedroom. I don't like it as much but if this is continue I may replace Apple TV.

Too many things have changed, like in any big company that gets too big for its britches sometimes I fear. It appears that even customer support in the stores has changed.

Thank you for all of your help!

I've never had this before, then had it twice of the the last 2 days...on 2 different AppleTVs connected to different TVs.

Reset is painless unless you have to do it every time you want to airplay or listen to some music.

Not happy.

I am having the same issues.. I have to unplug and plug my AppleTVs back in ... I own 6 AppleTV's and everyone of them does it. Everyone of them is directly plugged in via HDMI to the tv.. Audio only works for 5 minutes and then I need to unplug and plug back in... its the only way to get it to work.. I am about to box everyone of these things back up and take them back to the Apple store permanently. All this bullpucky about HDMI cables and tv models and safari versions is nonsense. APPLE TV DOES NOT WORK!!! I WILL NEVER RECOMMEND ONE TO ANYONE AGAIN! For the first time I will say Apple has seriously let me down. @internetmin get out of your state of denial and admit this is a worthless product.

Not sure if that's the same issue as mine, as a restart does fix mine until the next day it seems. Both of mine had been absolutely faultless until a couple of days ago, then both did the same thing.

Menu audio always works, but music, Netflix and airplay audio doesn't, very odd.

I'm just perplexed as to why they both started acting up at the same time, one is a v2, one a v3, both used for different things and in different rooms, connected to different devices..just weird.

My TV is fairly new. My apple tv is fairly new. I am tired of having to reboot!

I had noticed last week or so that a few had said that the problems started after Apple did the last update. I don't see those comments now but I may be too annoyed to notice properly.

Apple is a different company these past years.
One more time and I'll replace it with a Roku. Maybe not as useful but my son swears by theirs.

i just got the same issue, or almost the same.

have used ATV for the last three years, not a singel problem

Use Netflix alot.

last week Netflix started acting up, sound would only stay on for a few sec., if i paused movie, it would play sound for two seconds after play , then go mute.

So i go into TV show section from Apple, NO SOUND

Movies, preview, NO SOUND

BUT all the movies and TV series i have purchased HAVE SOUND ????????

i cant get it to work

ATV-hdmi into Pioneer LX83AVR to Pioneer KURO

if i play songs, sound is OK

i have tried to switch all off, change from HDMI to other inputs and back

i have pulled HDMI cable out and plugged back in again

AVR is set at Stereo

anyone have a clue

Yep, that sounds similar to my own. after both AppleTVs did it a couple of times, and were restarted, so far Ive not had a re-occurance yet.

it's almost like they catch a cold, and then they're ok again

The Reset, not restart, worked for me. But only for a few days. Now cannot play music either through ATV or Air Play streamed from iPad or iPhone through ATV. Movies, TV series I have purchased from iTunes works fine. Just not music. If I go to YouTube and stream from iPad to ATV a music video, get picture but no sound.

ATV to Samsung TV and Samsung Home Theatre. Is this a DRM issue? Don't want to have to Reset every time I use ATV.
