How do I set up a microphone connected to the USB-A port for the GC313/GC313Pro?

For the GC313/GC313Pro, the microphone connected to the A port is only functional with the signal source connected to the C1 port.

For example, if a Windows device (e.g., laptop) is connected to the C1 port, the microphone will be recognized as a Sound Input Device on that PC.

Important Notes:
If you are using the GC313Pro, please note:

• The microphone is only workable for the signal source connected to the C1 port.
• It cannot be used as microphone for the computer connected to the C2 port.
