If i set the Adjust display refresh rate to match, Sound doenst work anymore..

Which build? Stable? I never had this during the 2 years I have been using XBMC.

Adjust display refresh rate to match should always be set to match to keep a smooth playback without stuttering.

But with the gotham builds the xbmc gui refresh rate should be set to 23.98, otherwise passthrough doesn't work (and keep "Adjust display refresh rate to match", it will switch automatically and the sound passthrough will still work).

edit: ah zag was a couple seconds faster, yea so if there's a bug.... but still, works fine for me.

edit 2: and keep in mind that if Adjust display refresh rate to match is not ON, it is practically not possible to have smooth playback. This is the only way to avoid lost frames, unless you have a TV with very high refresh rates that can extrapolate to match.
