Fix for missing channels with Nommo V2

Right click speaker icon in the taskbar, select sounds. in the playback tab right click the Razer Nommo V2 and select properties. Go to enhancements, You might see things like Bass Management, Virtual surround etc.
In my case none were active, but in order to get the correct handling of THX sounds (like when playing movies) you need to check “Disable all enhancements”
