"It is further possible to buffer and synchronize screen updates with the audio DMA, but documentation of this feature is not yet available."

Perhaps there are some hints in the display driver source code?

Hmm... Interesting concept. Though since user apps don't access /dev/display directly (Hijack does that) I would imagine such functionality would require Hijack changes. And then there's that part about ti being not-yet-documented... If there is some documentation of this ability in empeg_display.c or empeg_audio3.c, I can't make sense of it. Maybe if one of the empeg guys in the know happens to stop by this thread, they could shed some light.
