What's the Story with Audio and Video Being Out of Sync?

[caltx01]

OK, guys, what's the scoop here? I am seeing this exact question on more and more forums so I know it is not a unique issue for me.

Every video player , every video format, whether local, streamed, stored on remote HD, cloud, regardless of player used or browser used - every video I play on my brand new Macbook Pro Retina 15 or on my 2012 Mac Mini goes out of sync with the audio after a while.

The video and audio always start out in perfect sync but soon begin to separate and the longer I play the video the worse the lag gets.

I am of the opinion that this is a problem with Yosemite because I never experienced it prior to upgrading when using the same browsers, players, files, memory, etc.

Has anybody else experienced this issue? I contacted Apple technical support but got nowhere with them - one guy told me it was probably becoming I am using a second vitro display with my mac.

I sure would appreciate any ideas if you have had a similar experience.

I'm on Mac-Forum's almost everyday…16+ hours/day, and I review/read almost every thread posted. I personally do not remember anyone here on Mac-Forums posting about this issue.

It is possible that I could have missed something. But even if I did…my point is…not many (if any) members have posted about it. We have lots & lots of members that are running Yosemite. I'm sure if this problem was:

- common
- fairly common
- not common
- unusual
- rare
- very rare

We would hear much more about it.

Are you using AirPlay by any chance? AirPlay in non-Apple software often results in audio out of sync (about 2 seconds or so by design - AirPlay needs a 2 second buffer which only Apple supplied products seem to account for).
