i have encounter a strange issue lately. after fresh install the kodi master nightly, i can set up audio passthrough without any issue. but after playing some videos and restart the kodi, all the audio passthrough options are gone, and after that all the audio will be transcoded to dolby 2.0. 
if i closed the kodi and clear its cache then start the kodi again, all the audio passthrough options come back and i get audio passthrough again for dts and eac3.  anyone have the idea what chould be the issue??

the stick is connected to the sony soundbar zf9
