No sound on Xumo TV with AirPlay

Currently have a 55-inch Xumo Tv. When I try to play a video over airplay to the Xumo TV the video plays fine on the Xumo TV but there is no sound on the Xumo TV. The sound on the Xumo Tv is not muted and I can turn up the volume on the Xumo Tv, but there still is no sound on the Xumo Tv. The Apple iPhone sound is up all the way and is also fully updated to latest version. The video is not restricted, because I can send the same exact video to my other Tv thru airplay and it plays perfect with video and sound. I went into settings on Xumo Tv and everything seems fine, I even factory reset the sound settings and still have the same problem when try to airplay on Xumo Tv. Any help would be great, because to me this makes no sense??
