mk808b hdmi audio

Hey folks,

I'm new to xbmc and the geekbuying mk808b. I'm running frodo 12.2 with android 4.2.2. When I try to change the audio of dvd playback from analog to hdmi i get a bunch of popping / crackling. Only way around this is to leave it on analog.

Have others seen this issue? Any work around or logs I can produce?

Thanks!
