AirPlay randomly change audio language on YouTube from MacBook Pro to Apple TV

I've also been driven nearly to madness with this same situation.

I have a work around but it sucks a bit. If you go into video quality setting and reduce the quality to 360p then it will be in the correct language.

I called Apple about this and they didn't have a clue about how to fix it and referred me to Google. Never could get any assistance from them at all.

It's a long shot but give this a try: boot into Safe Mode according to How to use safe mode on your Mac and test to see if the problem persists. Reboot normally and test again.

NOTE 1: Safe Mode boot can take up to 3 - 5 minutes as it's doing the following; 

• Verifies your startup disk and attempts to repair directory issues, if needed

• Loads only required kernel extensions (prevents 3rd party kernel/extensions from loading)

• Prevents Startup Items and Login Items from opening automatically

• Disables user-installed fonts 

• Deletes font caches, kernel cache, and other system cache files

NOTE 2: if you have a wireless keyboard with rechargeable batteries connect it with its charging cable before booting into Safe Mode. This makes it act as a wired keyboard as will insure a successful boot into Safe Mode.

Create and log into a new, basic, admin user account, Set up users, guests, and groups on Mac,  and see if the problem persists. This tells us if the problem is limited to your user account or is system wide.

Note:  do not launch any 3rd party apps in the account so as to not install any of the supporting files that most create.

If the problem isn't present then your original account has software installed that is causing the problem.  

I'm in this same AutoDub ****. It's so annoying and nothing seems to correct it. One of my favorite channels just went to auto dub for all videos and it's killing me.

Posting again as my first attempt apparently violated some kind of rule....

Add me to those experiencing this issue.

No, it isn't the setting on the receiving device, Apple TV in my case. I've checked the language settings on both devices. That is not the issue. Please don't suggest that it is and describe how to access these settings. It will not be helpful to do so. It isn't the issue!

My money is on Google and YouTube as the culprit. Causing this change in language to thwart ad blockers and/or VPNs. I don't have the time or energy to waste turning these things off. Using adblocker and VPNs make the web a tolerable experience. When I've had to access the web without ad blockers and a VPN the experience is awful and the web is nearly unusable. I can't fathom how anyone tolerates the mess. OK, back to the topic at hand...

It's a shame there doesn't appear to be a solution to this irritating situation. Could it be something in the latest Airplay code? That I don't know how to check.

PS. Surely this post doesn't violate the rules or offend anyone...

This has been happening on both of my apple TV's for what seems like a year now, and it's driving me insane. For me it's every youtube video I try to push via airplay. This is a major feature of the product/platform to just be totally non-functional, and can't believe it hasn't been addressed by now. This should be a non-existent issue with native apple products from the same brand.

Apple's OS' across the board have been getting buggier and more unstable, and my confidence with the direction of their software is at an all time low. I hope to god this particular bug gets sorted out soon.

same issue here.. from Italian to English...

This worked for me after months of messing about. Thanks. Apple really need to sort themselves out.
