I built a shuttle for my GF to play some games on and has been running perfectly for 2 months, last week she was playing and the sound just went really crackly. Sounds sorta like a radio not tuned in quite right.

I have tried a system restore, I have updated the drivers I have tried different speakers. It is crackly on both the front and rear jacks. Yesterday I tried doin the ACPI thingy but it made no difference.

I am at a complete loss? If all else fails I will buy a soundcard and stick it but I would rather not have to as it would use up the only PCI slot
