Question about Razer Kraken THX

Hello my name is William and here is the question: I use Razer synapse with the THX On, i select my video player with the surround sound ON for synapse. Here is, when i open video per video, sometimes it shows dolby - 2 channels, stereo, dts, 5.1 surround, dts - 6 channels, aac 2 channels. So... for me with the THX and Surround selected in the player by default, if it was YOURS, YOU SELECT STEREO for best option? because it has THX already...
