You tune the trumpet yourself.

(If drivers are installed)

My Computer-Change Settings-Sound, Voice and Audio Devices-

Sound and Audio Devices-Place the volume icon in the taskbar (selected)

When prompted that you do not have a digital signature and asked if you want to continue the installation, click Yes.

Otherwise, the driver cannot be installed.
