I'm almost certain that it is digital clipping that I've been experiencing. I've just gone into my sound settings. The strange thing is that last time I tried the test button, above 48,000 hz it said that the audio device was being used by another programme, so I left it at 48,000. This time the test worked fine at 96,000, so I'll try running it like that and see how I get on.
BTW, every time I've tried the WMA pro Audio test it's told me that it is being used by another programme. Should I check that box?
Thanks for prompting me to test again :)
Ah I see, the clipping is quite obvious it's like random instant interruptions in playback. You probably had music, an online video, a game, etc. going at the time. What really makes a difference is 16 bit to 24 bit, the sound of everything becomes fuller and more organic. Just select okay when it says that, it usually means you are playing an audio file of sort somewhere.
