I always listen to my favourite internet radio station through iTunes, however after upgrading to iTunes 12, I'm getting really loud white noise intermittently through the left channel, then right, sometimes both. Also, the quality seems to have taken a dive. When I stream through the radio station's website everything is perfect, with much better quality. Anyone else having these problems? To be honest I'm really disappointed about this, Apple have really screwed up one thing I really enjoy when sitting at my computer. Lastly, I found two threads on the Apple Support Forums from October this year where others are having the same problem!
