Hello
Unfortunately, I cannot get HBR audio (DTS-HD and dolby TrueHD) on my system
on all refresh rates. Only 59 and 60 Hz refresh rates are working more or less
properly: there's a dropout every now and then. Refresh rates below that are
silent: no error is reported by kodi or by the kernel bu
ork in progress. The result will also depend on your
graphic card.

I have a problem when playing dolby digital streams encoded at
640kbps. This problem occurs with mplayer or 'ac3dec -C'. When playing

This version is too old. You need at least 1.0.13 (which may be part
of kernel 2.6.20, but I'm not sure)
Or you can try 1.0.14rc3.
