<pre>I've a Mobility Radeon HD 5650 muxed with an intel card. If I boot with
radeon.audio=1 and I switch the radeon card off when pulseaudio is running,
then the kernel hangs as soon as I close X:

These errors doesn't happen instead if I close X and kill pulseaudio before
switching cards.
Not sure if this is a pulseaudio issue or a kernel one (that should notify
pulseaudio about the unplugged HDMI audio card).</pre>
