A running process already owns Mapper and won't release it to Vegas.

Close Vegas.

Disable all sound devices and processes.. May be running in background!

Open Vegas.

Select only ASIO audio drivers from Preferences..

Close Vegas and reboot your system.

Go to Task Manager, check for processes that loaded at startup.

Sorted ! Turns out I had a second audio codec for my streaming that was effecting it. Thank you though I appreciate your help!!

You are welcome.

Please check here first before installing third party codecs on an editing system. Goes double if you are running games on the same machine (not recommended).
