I'm not sure if Win10 has a built in sound recorder, if not try an independent program (that does not use the network) just to verify that your mic, sound drivers etc are ok.
Its an overkill but audacity will allow you to record and play back
http://www.audacityteam.org/Also check that TS is running in elevated status. Find the shortcut to TS, select properties and tick the "run as admin" box.
Can audacity manage microphones and TS3 issues? How it'll be? I check on audacity guides and I download it too, but I didn't find about that. How can I use that?
