What all extra are you running on the laptop?  For example, are
you running the FrameBuffer console or X?  Either of these might
take up enough interrupts to cause the bad sound quality.

In terms of CPU usage, what is the load average on the system?
I'd worry less about total CPU usage on laptops, as some of the
more recent systems put the CPU in low power mode when there
isn't much load to save battery life (thus CPU percentage is
higher per process).
