No sound on all links

I have sheild box with Amazon TV all of my links play with no sound. I've tried different TVs and my mute is off and I checked the the sound settings in Kodi. Umbrella, pov, red light, seren, and the crew all no sound. I checked multiple links on multiple movies. Small and large sizes of links. They all play but no sound. I was wondering if it is just me or is it a Rd issue. I deleted kodi and even reinstalled with diggz still no sound. My guess is it is a rd issue. Any help or ideas would be much appreciated.
