I use the Samsung Gear VR (model SM-R324) with a Samsung Galaxy S8+. A few days ago it was possible to change the volume while being in VR mode. But yesterday it did not work anymore. Neither with the volume buttons on the headset nor with the controller. The volume bar appeared in the middle of the screen, but did not change the volume at all. Of course I restarted the Oculus app, but no change. What could be wrong?
And I noticed that I do not have sound in YouTube VR at all. But sound is not muted there. When I try to change the volume there I get something like "Please change the volume in the Andoid settings". But sound in the Oculus menu and in the browser works fine. What can I do?
