The timer was just a workaround and known regression of the usermode ddx. The hardware is capable of raising an IRQ on audio start/stop (the IRQ gets actually raised on any change of the audio settings, which the video driver must recognize to update the various hdmi settings). At the time of writing this patch the IRQ code wasn't available so I just used the same workaround as the ddx, we should get rid of it as soon as stable IRQ support is available.
