Hi,
My main desktop machine has suddenly become very noisy - any user activity is triggering a barrage of "pops" out of the speakers. The more intensive the use, the more pops I hear. Even scrolling the browser window with the mouse results in noise, so you can imagine how impractical playing DVDs has become. I know the speakers are OK because I get the same results with a pair of headphones plugged into the sound card's "Analog Out" jack socket instead.
I've looked inside the PC's case and can't see any obvious problem. Can anyone suggest what might be going wrong, please? The sound card is an Audigy 2, and I am running a 2.6.31.5 kernel, just in case this might be a driver problem rather than a hardware problem.
Thanks for any ideas,
Chris
Other points:
- My sound card doesn't share an IRQ with anything else.
- Audio-only applications don't seem to have a problem. (Not CPU-intensive enough? No video update?)
- I am running Fedora 11, which puts PulseAudio between me and any audio.
- Fedora 11 plays havok with my mixer settings. Could some combination of settings be creating interference on one of the output channels?
