any update on this?

I have tried this on nRF5_SDK_17.0.0_9d13099 and it does not seems to work.

I can output the audio, LED1(USB bus), LED3(USB stream receive), and LED4(USB stream transmit) is on but not LED2(USB device library).

The play back seems to work fine but when try to record Audacity receive data for a split second and stuck.

I'm on MacOS

I've tested all versions from 15.0.0 upwards. Conclusions:

It does work on windows (I misconfigured the mic volume so I didnt see activity) - ALL versions of usb_audio work on windows 10; both compiled and precompiled versions (the ones in the hex folder)
The microphone isnt detected under Linux no matter the version or the use of compiled/precompiled
If I remove the headset device and change the mic to this:
#define MIC_INTERFACES_CONFIG() APP_USBD_AUDIO_CONFIG_IN(0, 1)
.. the mic is detected under Linux and works (in my code) however the output is distorted (same problem in my other questions)

Seems SDK15.2 of \usbd_audio works, but SDK15.3 doesn't, if you can you confirm then I will report it.
