I'm trying to record audio from the analog input device of my card, but whenever there seems to be some graphics intensive activity like glxgears, OpenGL assisted window manager, audacity graphs etc... a noise appears in the recording which sounds like some kind of sparking disturbance.
Sudden changes in power consumption will affect the voltage on the power lines. (If the GPU is powered only from the mainboard, there is not much your PSU could do against this.) Your card (whatever it is) apparently is not properly isolated against such fluctuations.
