How can I setup a 3 channel soundbar in ps5 without being in stereo PCM


Novice Member
I have an LG c2 with a 3 channel eARC soundbar. TV is on bitstream and passthrough. On the ps5 if I use soundbar it doesn’t play all the channels such as an actor off screen the sound doesn’t come through if I set 5.1 AVR I get multi channel PCM but same issue. I know it’s not 5.1 anyway This isn’t an issue on my PC because I have speaker fill. It does the same thing with Dolby on soundbar and AVR 5.1 it won’t use the other speakers in front channels. The only way to fix this is to set 2 channel AVR and linear PCM all the channels work correctly now but I can’t use Dolby even in 2 channel because the same issue happens and it defaults to Stereo in linear PCM which is what I have to use to get the channels working correctly. Is there any way to use 3 channels without getting just stereo?
