This is Already adjusted in #16490. this pr will cause conflict.

Ok, I will fix then the conflict manually in #16490 after this is merged.

@mltony - can you share your thoughts on this? My understanding is that the documentation is correct, and the settings are wrong. We should fix the setting to correctly select left/right splitting only by default.

@seanbudd, this PR makes sense. Sorry for late reply. I updated these setttings because many people were pushing for having a proper disable sound split state. But I forgot to update docs, so this PR fixes that. many
