Bad comms

Although recently signed up I have had great fun adding on many aircraft from this site and due to a PC crash I reloaded FSX from scratch and eventually managed to also install Service pack 1. Everything seemed OK except that NOW & AGAIN voice OF ATC gets scrambled up with accompanying buzz.
Also the FSX background intro music is poor and jumpy, and on starting up FSX I get a female voice , unitelligable, just part of one word!!! Weird, any ideas as it all worked fine for the last few months (without SP1).
