PluggableUSBAudio not working

Trying this example:

#include "PluggableUSBAudio.h"
USBAudio audio(true, 44100, 2, 44100, 2);
static uint8_t buf[128];

void setup() {
for (int i = 0; i

Start by reproducing the sketch from the issue with PluggableUSBAudio.h on the Pico, then inspect the USB enumeration path involved when it remains a USB Serial device instead of Mbed Audio. Done means the example enumerates as Mbed Audio and audio.write produces the expected USB audio behavior.
