LG 7450PLA and AAC passthrough


Novice Member
Hi there.
My LG 707450PLA is a great choice and value for the money, but I 'm unable to send AAC multichannel to my AVR.
My Denon likes AAC and knows what to do with it. It works with media players, Raspberry or Kodi.

But my LG TV seems to convert every file to AC3 first, no matter what I do, no matter what app used to play the files. I tried every setting and changed from optical to HDMI/ARC, but my AVR always gets DD instead of AAC/multichannel.

Has anyone any idea or is it not possible to pass-through AAC to my Denon with this TV?
Thanx very much!

Very unlikely it supports passing AAC 5.1

LG dont support much beyond the basics of PCM 2.0, Dolby 5.1, even on latest TV's with eARC support LG dont support PCM 5.1 on internal apps.

unlikely ... passing AAC 5.1

Never thought of that. No codecs needed , no licenses, no fees...just passthrough, it shouldn't be a challenge after all.
But that's possible. Guess, I will write to LG for clarification. Maybe I'll get an answer....

Thanks very much and Greetings!
