Package: alsa-base
Version: 1.0.21+dfsg-2
Severity: important
A crackling or white noise sound is present whenever an animation is shown
on the screen. Animation is to be understood as animation in the widest sense.
Even on console, if the cursor is moved, a noise is audible. It also applies to
mouse movements both on gnome or kde 4.
I've tried disabling pulseaudio server, without any effect. The sound hardware
is discovered correctly as nvidia mcp65 on board-sound. Before upgrading the
system to debian squeeze, it was running debian etch without any sound
issues. So i don't think it is a hardware related problem (like electrical
field noise inside the box).
Although it seems related to the graphics system, i'm attaching the output
of lspci | grep vga below:
