I have a 2 year old LG 47 SL90. The audio output is digital. If your audio equipment doesn't accept digital input, you need to get a digital to analog converter like I did. If you use the digital output, bear in mind that the TV volume control doesn't affect the digital output level.
So I've bought an LG 47LM620S tv and I'm having some problems with audio output. I've connected my "old" DVD Receiver (HT-153) from Eltax to my tv through the (RGB) AV1 output from tv to AUX input from dvd. Well now if my tv (that's playing a TV channel through Cable) is set to tv speakers it plays audio at both sources. When tv is set to external speakers it doesn't happen, only sound from dvd. Now, no big deal.
I've got a Wii U connected to tv with hdmi cable. Now I want the audio through the dvd but the dvd stills plays audio from the last tv channel I played. Of course when I set tv option to tv speakers I get sound from Wii U through that and the dvd still plays channel audio. Same happens when using SmartShare|Plex|DLNA|Media Servers.
Now I'm thinking that the external speaker audio option only works on LG products since it mention Simplelink information or I'm using a wrong output. Also I have an option to automaticly choose digital sound output or set to PCM. And there's a choice to put ARC mode on or off.
I could use the headphone output but even at max volume the sound is pretty quiet.
Any other ideas. I have an Optical Digital Audio output but dvd has no such input.
Thanks for the help.
