ESP-IDF defaults CONFIG_FREERTOS_HZ to 100, so the audio task wakes only every 10 ms and can't service the 1 ms UAC iso frames -> underrun -> arecord EIO. (The same dwc2 driver passes on STM32, whose FreeRTOSConfig is 1000 Hz.) Set CONFIG_FREERTOS_HZ=1000 in the example sdkconfig.defaults; the example defaults are honored in the generated sdkconfig alongside the BSP's, so this takes effect. metro_m4_express (samd51): not tick-rate -- its FreeRTOSConfig is already 1000 Hz like the passing boards -- so it's a separate iso-IN issue, skipped for now.
