Hiya guys, I previously used onboard HD audio on my Asus P5Q Pro Motherboard, and Creative Megaworks THX speakers, I had this setup for about 8 years until the speakers died on me. I bought an Asus Xonar DX sound card, and some Corsair SP2500 speakers, been using them for about 3 months. About 3 weeks after installing everything, my misses was watching a Youtube video, and the speakers let out a massively loud hissing static noise, it was so loud it made her jump, I was convinced the noise would blow the speakers, in panic she turned off the speaker. I turned it back on and everything was fine again. This happened again about 6 weeks later, when watching a video on facebook, it proper made me jump, once again, a turn off of the speaker and turn on fixed it. Today it's happened again, no videos were playing I was just looking on Google, the noise kicked in on just the search results, no audio or video playing at all. Frightened the life out of me. What;s causing this? The only way to describe the noise is its a similar noise to an anologue TV, remember when you had to tune in the Telly? and you had those black and white dots until you found a picture, and the hissing noise it gave off? Its like like, but max volume! Someone suggested an issue with Flash, so I updated it, no change, after the first time I changed my sound drivers, same results, and I have also checked all cables etc.
