how to reduce 'noise' with onboard sound (realtek hd)

[bledd]

ie, when you scroll wheel in firefox, you can hear a slight fissle through headphones

are there any bios settings that can help this?

my xfi is in my media centre, and given the hassle it has with vista, i'll leave it where it is (in a vista box, but thankfully not giving me any gyp)

i'd rather live with this for now than buy a sound card, money is tight and you can't tell it's there when playing games anyway

suggestions?

damn, that's retarded, can't they just supply the audio on a pci/pci-e card instead of putting it on the motherboard, surely easier for them & better for customer

just nead a cheapish soundcard that works perfectly in xp/vista 64 then :/

any 2nd hand cards to look out for? infact i've got an sb live 24bit at home somewhere
