PC speaker control is not possible because the %a driver contained in inpout32.dll couldn't be installed when Bawami started running. This is probably because Bawami was not "run as an administrator".

To fix this, please simply run Bawami as an administrator by right-clicking Bawami.exe and choosing the option. The driver will be installed automatically.

This only needs to be done once. Afterwards, the PC speaker can be used even when you start Bawami in the normal way.
