Since some time I have a new system with a MSI K8T NEO FIS2R mainboard. This mainboard has an onboard sound module that is adressed through the wellknown AC97 codec. Anyhow... the sound it produces is great, it has lots of functionality etc etc.... there's just one thing: there's always some kind of irritating background noise in the sound. It sounds like back in the old days, when CD drives still caused these kind of disturbances on the sound card.; it's like I can hear the engines of my harddrives running through the sound card... The sound isn't that loud, but when using headphones it annoys me quite fast.
Any thoughts on how to solve this (without putting in an addiional sound card)?
