Hello,
For the sound problem, make sure you've installed the drivers for the device.
For the second problem where your @ and " keys are swapped, you're not alone...! It happens alot...
...to fix this, go to Start > Control Panel > Regional and Lanuguage Options > Make sure that English (United Kingdom) is selected in the Regional Options tab > Then click on the Languages tag > Click the Details... button > When the Text services and input languages window appears, ensure that English (United Kingdom) - United Kingdom is chosen as the Default input language > Under installed services, click add. Once the Add input language window appears, select the input language English (United Kingdom), check the Keyboard Layout/IME checkbox, then in the dropdown menu select United Kingdom Extended > Then Apply and ok all windows.
