It’s a free virtual surround then you try to make a call with Skype
Problem with callback device
It is because razer install new sound driver and Skype is not yet configured to use that driver
To fix it, just Call->Audio Setting
Speakers –> choose whichever contains word Razer
Anyway, to test razer surround sound, just don’t use you tube, use something with real support of 7.1, not that bad, really..
