No sound in Kodi 17.1

Did a fresh Linux Mint 18.1 install yesterday and the whole system works. I have full sound in all the music players and video players I have installed. I then installed a fresh Kodi 17.1 setup and everything seems to work fine. I can find all of my drives and all of my videos and music. I installed nextPVR and can stream live TV but in the upper right hand corner of Kodi is a red box with the “sound” icon crossed out. I have no sound in Kodi and can’t seem to get it working… Anyone have this problem in the past or now? Just looking to see if anyone has a quick fix. TIA!
