The mute is done on the audio device. This is from, to put it in a short answer, how it works today.
Nothing in the user manuals at LG tell us that HDMI OUT (let's be clear here, that would be ARC) says the audio would mute. Time to ask LG directly.
Hello Learned experts.
I am not able to get my new, highly expensive TV to work with my 25 year old Panasonic/ Technics sound system-- correctly.
LG TV: 4K HD OLED65B7A
Sound System: Panasonic / Technics AV receiver, mod DX930
I believe all my setup is correct, gone through it many times.
Problem: OPTICAL cable output generated by TV to receiver appears "dumb" because when using TV remote(programmed for Sound system) it mutes only the TV and modulates ONLY the TV-- not the signal going to the receiver. I am forced to manually adjust sound system at receiver.
Question: If I bought an HDMI / optical adapter and used the TV's HDMI output is there one available that WILL be muted and modulated by the TV or will it just strip off the same optical signal I am getting now? Can you recommend one that works.
Question #2: I figure there is no solution for #1. If so, conclusion is to buy a new Denon receiver to enable newer Sound effects software in use today not around 25 years ago. Suggestions for which Denon sound receiver may be a good choice?
