## Description of change
Part 1)
When ASIO is in use, the game also looks for a Realtek device so that it
can open a WASAPI Exclusive mode stream for headphones.
Add an option to fake that, in case the user doesn't have a Realtek
device.
Part 2)
`-gdaasio` wasn't workign properly - fix the logic.
## Testing
Seems to work with FlexASIO, and Xonar with no real Realtek device.
