Same problem here as with 90%+ of others experiencing this problem.
I purchased my AirPods Pro 2 from an Apple retail store 2 weeks ago and purchased an additional pair for my daughter from a popular online retail store in which Apple have their own store page within. Admittedly I was waiting to test my daughter’s AirPods Pro 2 and they have the same issue, which is no surprise when seeing this thread.
The problem is as has been mentioned many times. Loosing the sound (the audio stream that is) when pausing and then resuming playback of video; it may not happen on the first time you pause, but it will certainly happen soon after in subsequent pauses and resumes. Also when forwarding/rewinding playback of a stream and then resuming normal playback. Also merely watching YouTube videos and refraining from pausing or fast-forwarding/rewinding in an attempt to avoid the bug from occurring becomes utterly futile as the countless YouTube ads will often invoke the glitchy AirPods Pro 2 sound stream loss issue. Changing the source channel, ie. from say one streaming service provider to another, or to the TV’s freeview channels also invokes the issue. There’s literally no escape from the problem.
Admittedly I too had found out that the temporary fix was to change the output source from AirPods Pro 2, to the TV’s Speakers and then back to the AirPods Pro 2 again. However it really is only temporary, for the minute you pause the video to attend to something, or rewind something you’ve missed or want to watch a scheduled reminder of a TV show, then your in trouble again as you have to keep doing the temporary fix again. Worse still if your watching a YouTube video with several ads contained within it, then I dont have to tell you how fatiguing it becomes doing the temporary fix procedure several times during just one video alone.
I must point out that sometimes it’s sound loss and sometimes the sound becomes broken-up and crackly, which then eventually becomes altogether lost.
I had done everything conceivably possible, which included just about everything that has been mentioned so far in it’s entirety - except turning the attached AirPods Pro 2’s volume down to zero on the TV setting and then turning it all the way back up, however this also proved ineffective.
Also as with what many others have reported; I too had no problem of this kind with other AirPod models. My AirPods gen 2 and AirPods gen 3 never lost the audio stream when using with the same TV unit. Even my ancient Bluetooth pendant I own (of many years old) in which you plug-in wired earphones of your choice never has its audio stream lost.
Its a shocking issue to say the least and left further exacerbated in disbelieve that after much time the problem ‘still’ persists.
Bluetooth is a certain wireless TX/RX standard which the AirPods Pro 2 have adopted (Bluetooth v5.3 I believe, unless mistaken) in which latter versions are backward compliant to older versions. However the AirPods Pro 2 don’t appear to be fully nor properly compliant to that standard it has embraced with the existence of this enjoyment-breaking issue.
