Audigy Digital line out problems?

[yan816]

I seem to be having problems with my digital line out going to a DD decoder and speakers. Everything seemed fine untill a few days ago untill I installed water cooling, now all I seem to hear is a crackle/buzz. The pump is an ehiem 1250 going to a PCI relay card, is there a chance that the pump or a slight vibration from the water cooling is interfering with the sound card? Anything else it could be? Please help.

have you tried moving the Audigy to a different slot ?

If it was an analog out I'd say it was interference from the pump (it's power supply... or maybe the motor if it's close enough)... But that shouldn't happen with digital... But maybe it is... As BlackSheep said - try another slot - try and keep as much distance between the relay card and anything else in the system. Also if the relay card is passing mains voltage and isn't thoroughly insulated you might want to think of another way to power the pump (as it's dangerous as well as causing you problems)

also what type of digital connection is it? optical or co-ax as that could possibly have an effect

I have tried different slots and that does not seem to help. It is a coax connection. Any thing else I could try? Thanks.

You got another computer you can try the sound card out in to check the card itself hasnt been damaged somehow?
