I suspect a dying power supply but wanted to make sure. My headless debian dockstar has started playing static through speakers (attached to a USB sound card). It also plays static whenever I do any activity on the remote ssh console. Say dmesg or even ls. I also nsoticed that it does make a sound when I am running top and the programs swap places in the display.
Looks like any I/O activity triggers it.
Has anybody else experienced this? How do I debug this? Any suggestions? Other than replacing the power supply ;-)
