I bought the Logitech G432 and wanted to ask if there's any surround sound on the Xbox.
and if so how do I turn it on or is it already on board?
Of course there's surround sound. So to ask such a question!
Both Dolby Digital, Dolby Atmos and DTS are available. The whole you can find on Settings, Display & Sound and there on audio output. Here you will find all the necessary settings.
