What should I do if there is no sound in the USB input?
Because both the USB input and the Bluetooth input use the same module, the Bluetooth input has a higher priority. After switching to the Bluetooth input mode, if a mobile phone has been connected to the Bluetooth of the amplifier, the amplifier will play any sound from the mobile phone and play the Bluetooth input first. audio, thereby cutting off the USB input. If there is no sound from the USB input, first stop the Bluetooth playback of the mobile phone, and then check whether the playback device of the computer is set as the default device for the USB device. If not, just set the USB device as default.
