Hi, have you found something work for you ?
Happens to me as well but not started in mavericks all started with Mountain Lion , a few weeks before he left mavericks , I thought the problme would be solved by updating , but he did not, it's very frustrating strange thing is that in my case not only iTunes is , if any player, have proven Vox and another which I forget the name .
I also feel the same when you play a song in quick look ( Finder) .
I am desperate this problem is with me for the last month and a half went to a apple store and tell me that my machine has nothing that can not help me, and tried everything , reset my machine with a clean install , restart PRAM , repair permissions hise disk hardware test , and nothing has changed.
When iTunes pause my machine freezes a moment and returns to normal when continuous playback , stops about 1s though sometimes hard to 5s .
We appreciate if you find solution , because I am going crazy . Since neither in apple have been able to help me .
My machine is a Macbook Pro late 2012. Mavericks , iTunes 11.1.3 did not correct my mistakes. Do not know what else to try .
😟
