[Galaxy Tab Pro 12.2, 10.1, 8.4 Q&A, Help & Trouble] banjo3009:
Hello everyone,

I have installed lineage-13.0-20170114-UNOFFICIAL-n2awifi of the tab pro 10.1 but having issues without volume when playing video.

I have found instructions online to modify the mixer_paths.xml file but It seems that some volume entries are missing. At the bottom of the post is the mixer_paths.xml content.

Does anyone know if something is missing from the file or what needs to be modified?

Thanks!
