How do I add volume controls to a device that doesn't have them?

Sound Control adds volume controls to audio devices that don't have them. There are 2 different types:

1. Audio devices that have no volume controls.

2. Audio devices that have volume controls that don't work. 

1. Audio devices that have no volume controls.

When Sound Control is turned on, these devices will automatically gain software volume. Your volume keys and volume control in Sound Control will work.

2. Audio devices that have volume controls that don't work. 

For these devices, you must tell Sound Control to add software volume to them.

To do so:

1. Show settings for the device.

2. Turn on "Virtual volume"

Now, this device will have software volume applied to it by Sound Control.
