Thought I'd try out itunes and SS3.1 as a precursor to possibly buying a portable. Had old version SS on my laptop already (Sony Vaio) and upgraded to 3.1, itunes had to install from scratch. And....the sound quality playing tracks on itunes is diabolical. All distorted and unlistenable - I'm not talking about poor quality, I mean it's awful. Has anyone else experienced this? I even tried reinstalling, but no better. BTW, sound quality of same tracks on SS3.1, Windows media player etc. is fine.
