As the title states, I'm having difficulty playing 5.1 sound from a 5.1 set up. It sounds like the center channel is just being played through all the surround speakers, even though Dolby Atmos tracks and 7.1 (which DA usually unfolds to anyway) play fine.
For my set up, I have an LG CX 48" OLED, an LG SN6Y 3.1 soundbar (connected to eARC), and the LG SPK8-S wireless surround speakers. Media playback is from a PS5, configured for an AV amplifier (suggested by an IGN article) with a 5.1 set up.
Strangely, or what I find strange, is that 5.1 streaming sources sound fine, it's just discs.
