As of recently, my 2.2 MBP's had some odd issues with the audio. While running, it makes these soft little clicking noises. Also, it will start "skipping" whatever audio is playing, iTunes, streaming videos, whatever it might be. Also, sometimes, with earphones, it will sporadically switch between playing through the speakers and the earphones, even though the earphones are fully in the port. Lastly, this leads me to believe that it may be a hardware issue, but this occurs both in Leopard as well as Boot Camp in XP. Anyone experienced this, know what's wrong, or just have some general advice? I'd take it to an Apple Store, but the nearest one is about two hours away, and I literally have no time to spare until April, earliest.
