This is driving me nuts, and I hope one of you fine people can help me. Maybe I should just go to a Genius about this, but I haven't asked a question in so long.
My computer is exhibiting some strange audio behavior. When I'm using iTunes, there's a short lag before the track starts playing. And by that I don't mean I'll try to start playing the track, have to wait a little bit, and then it plays as expected. I mean I'll start playing the track, it'll go for a (very) short time, and then the audio will start after that delay, causing me to miss a little bit.
For a specific example, when I'm playing the Beatles' "Please Mr. Postman"
, the audio will come in as "-ait!", missing the hi-hat and "w" at the beginning. It's not much of a delay, but it's crucial. And annoying.
To make it even better, this is a problem that's both consistent and
inconsistent. It happens all the time, but only if there's been some time since audio has been played. I can play something, get the delay, then immediately play it again and the delay is gone. But if I wait for a while (a minute? 30 seconds? I haven't had the patience to be really scientific about this), the delay will be back. And on top of that, iTunes is the only program I've found that has this problem. Anything else plays fine. And anything can act as the audio primer for iTunes to act fine, too.
I don't imagine it's something with the hardware, since other programs will play audio fine. And iTunes shows the same behavior on audio output in general, like when I have headphones plugged in.
This is a 2011 MBP, model identifier MacBookPro8,2. It's running Mac OS X 10.6.8, and I'm using iTunes 10.6.1 (7). I can't remember when this started, but it's been going on for a while.
