Yes. It is easy almost all of them even the cheapest nasty ones from
Aldi/Lidl produce a composite video out and a mono sound channel. The
only snag is that you have to change from TV to another input.
How many TVs have an analogue input these days? I had to search for one
which still had a SCART. Most are HDMI and USB only.
My newish 4k TV has analogue inputs, not SCART though.
It also has both terrestrial (digital and analogue) and sat (digital)
tuners.
I expect the chipset does them all so they are probably more common than
you think.
What I don't understand is why it decodes DTS when it only has two
speakers unless it puts decoded multi channel PCM over the optical
output? I don't think that's very standard though.
