I'm currently working on configuring the USB audio gadget (g_audio) on my Orange Pi 5B to ensure both the speaker and microphone are recognized by the host PC. However, I am facing an issue where only the speaker (playback) interface shows up on the host, while the microphone (capture) interface does not.

 

Here are the steps I have followed so far:

 

1.Kernel Modules Loaded:

sudo modprobe dwc3

sudo modprobe dwc3-gadget

sudo modprobe libcomposite

sudo modprobe g_audio

 

2.Unloaded and Reloaded g_audio Module with Parameters:

sudo modprobe -r g_audio
sudo modprobe g_audio p_chmask=0x3 c_chmask=0x3 p_srate=48000 c_srate=48000

3. Bind the Gadget to the USB Controller:

echo "$(ls /sys/class/udc)" > /sys/kernel/config/usb_gadget/g1/UDC

Despite these steps, the host PC only recognizes the playback interface. 

How can I configure the g_audio USB gadget on the Orange Pi 5B to ensure that both the speaker (playback) and microphone (capture) interfaces are recognized by the host PC? Are there any additional steps or configurations that I might be missing?

 

Any help or guidance would be greatly appreciated!

 

Thank you in advance.
