[alsa-devel] opengl 'leaking' sound to input.

[dE]

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.

I've recorded audio many times on this box before, but this started to 
happen suddenly (maybe after an ugprade, but old live CDs with 
proprietary nvidia drivers installed or newer nouveau drivers seem to 
have the same issue).

Just to confirm, is this a hardware issue?
