No.  disabling audio in the radeon driver just disables the audio stream in the
hdmi stream.  The audio device itself can't be disabled.

If you disable acceleration (add Option "NoAccel" "true" to the device section
of your xorg config) do you still get the problems?  It's most likely some
issue related to the 3D engine set up in mesa.
