Just bought an OTT Set Top Box, Model number M8S Running Kodi v16.1 under Android 4.4.2. This application was working just fine out of the box. I was watching Breaking Bad Season 2 this morning then had to give the eyes a rest. I left the set top box powered on with the Kodi app running. When I returned to it the video would play but there was no audio output. I quickly noticed that in the upper right hand corner of the screen, just to the right of the current time there was (and still is) a speaker icon in red with a diagonal slash through it. This ‘no audio’ alert icon appears only in Kodi and all of the other apps on the set top box have normal audio output. I hadn’t changed anything in the settings of the set top box or the Kodi app itself. I just left the box powered up while I ran some errands. Since then I have spent hours trying to resolve the issue. There are numerous articles and Youtube videos that seem to address this problem but they all involve changing the audio output device from within Kodi. Unfortunately this option is greyed out and set to: Android, Audiotrack.
About the only thing that I can think of that would cause this issue without any user input is that if while I was running errands the Kodi application underwent an update that is causing the audio problem.
I have searched high and low on the internet and these forums to no avail. If anyone can lend a hand with some suggestions, I would be most appreciative.
Thanks in advance for your support.
