Action not recording Teamspeak?

[MartyMCP]

I recently recorded my first video since upgrading to Windows 10 and it all went smoothly apart from the teamspeak recording which didn't record at all. Everything is set up the way I usually have it but for some reason it just didn't bother recording the Teamspeak channel and I thought that's what the "Record windows sounds" box was supposed to do. That's checked and it's only recorded game sound.
