I get TV sound through the audio video system. Furion TV and Furion DV 3200 it is connected by AV cables from the factory. My complaint is that 2017 should have come with a Blu Ray player and an HDMI cable connecting the TV and AV unit. I plan on fishing an HDMI cable from the TV to the AV unit since the AV unit has an HDMI input in the back.
On another note we have used screen mirroring from out tablets to TV for Netflix etc. using a Screen Beam Mini 2
