On almost all TVs the optical is an OUTPUT. And the Freeview box should be an OUTPUT as well. Since the TV can output on optical I'd change the sound bar connection from HDMI to Optical from TV to Soundbar and resetup as needed.
I have the following:
Tv – LG 50PC55
DVD – LG HT304SU
Soundbar – 2430A
Freeview box (Humax) is connected to tv via Hdmi, and optical from Freeview to tv.
Dvd connected to tv via scart..
All was ok until this week when I purchased the above soundbar. Now, when I turn on the soundbar, it also powers the dvd player on. This can be very annoying if there is a dvd in the player, as I get both the sound from the dvd and the freeview at the same time.
Is there a way to stop the soundbar remote from powering up the dvd player please?
