I don't see why not. I have an optical to phono output on the Samsung bought
from Amazon. The only issue I had was that hdmi lead to pc, put pc sound
into tv after the optical output, so had to pretend it was not hdmi by using
a vga to hdmi box and leaving the sound going via my external sound card
which has phonos too, so one could simply switch it as another source. I
have an annoying pulse though tht goes sheesh every few seconds if the hdmi
is connected on any input, Suspect some polling from the TV even in standby
is actually getting in via an earth loop somewhere, but I guess I will find
it in the end!
I do find however that modern tvs max output via line on these dongles is a
lot lower than the sound effects the TV makes and all other sound inputs so
one obviously does need some kind of level adjustment device I think. Too
many different standards, clearly!

I am not sure if this is the correct NG but here goes.
I have a vintage Techics Hi-fi system that has stood idle since the
arrival of widescreen TV, mainly because it is on the opposite side of
the room.

The TV is connected to a computer that runs Mythtv an serves as an HTPC.
It has a cheap 3-speaker pc system that is an improvement on the TV's
speaker but is in no way "good".

We plan to move and I wondered if the hi-fi system could be geared to the
TV and /or computer. I am uncertain as to the best way to connect up.

Inputs to tha ampifier are all phono sockets.
