Distorted sound with pass-through on Vizio 5.1 soundbar.

Try changing to 'Fixed output' in 'Settings > System > Volume mode' and turning the volume all the way up in Kodi (right joystick).

Tried it, same results. Same thing happened on my RK3288 Beelink r89 device. The fix was I had to use optical out to the soundbar, the shield only has hdmi. The Netflix app doesn't play any videos with 5.1 either. Strange my PS3 hdmi bitstream works just fine.

Shield HDMI -> TCL TV -> COAX SPDIF -> VIZIO 5.1
