I have a few films which have multiple audio tracks. The default is usually Russian language, with English or commentary as tracks 2 and 3. OSMC can handle this. You simply go into the options when playing the video and select the audio track you want. However, lately there is an issue. I often don’t watch a movie in one sitting. When I stop these files, then go to resume them later, the audio reverts to the default audio track and the additional audio tracks disappear from the selection menu. Usually, restarting OSMC fixes the issue and makes the audio tracks available for selection again.
I thought I’d mention this in case anyone else has had this issue.
Thanks!
