I have been having this crazy little problem with my sound.
i have gigabyte z390 MB with Realtek on board sound with the updated drivers from the gigabute website.

when i set my sound in windows or the realtek audio console to 5.1 and test it it all seems fine
left , right , center , Rrear ,Lrear and sub all make sound as they should from the corect speaker.

but when i play games or watch video on chrome it seems like all the sound moves over to the left speaker.
it almost sounds like anything outside of windows itseld defaults to 2.0

there is sound in both left and right speakers but the left is much louder then the right (in games /browser)

a 5.1 test on youtube says

Left (left speaker)
Center (left speaker)
right (right speaker low)
RR (Right speaker low)
LR (left speaker)
Sub (nothing)

like i said like a busted 2.0 system
please help !
