It is turned to the maximum, but the volume is still not loud enough. What should I do?

This audio amplifier is designed with a gain switch,which can be set to “H” position if the sound is not loud enough.

Does Type-C have a decoding function?

Type-C of the headphone amplifier only has a charge function, does not have OTG decoding function.

All cables are connected, but there is no audio output?

Why the headphone has a big buzzing sound when the input cable is connected but the sound is not play?
