The other day I had audio using Kodi today I don't. I have tried TV shows in 1Ch**nel and a movie in Genesis. I have sound on my computer. The audi levels within the Kodi video player are up. I can not see any mute buttons (is there one?). There is a speaker symbol on the top right corner of the screen with a red line through it. It was there the other day too when I had audio. Please help.
