audio_player在MicroPython下无法运行怎么解决？

我们参考 IDF/ADF/MicroPython_ADF 的说明将它们进行了整合，Python 的 REPL 工作基本正常，ADF下的play_mp3_control 在脱离MicroPython的环境下单独编译、运行也正常。
但在MicroPython中，通过MicroPython_ADF下的 audio_player 模块播放mp3失败。
IDF/ADF/MicroPython均为主线最新代码。

测试的命令为：
#sdcard
import machine, os
sd = machine.SDCard(slot=1)
os.mount(sd, "/sdcard")
# Add libs in sdcard to sys.path
import sys
sys.path.append('/sdcard')
#Audio
from audio import player, recorder

def cb(state):
    print(state)

p = player(cb)
p.get_state()
p.play("file://sdcard/music-16b-2c-8000hz.mp3")

在执行到最后一步的时候出错，Log为：

根据Log查看 gc.c:460 行为：
459    // check if GC is locked
460    if (MP_STATE_THREAD(gc_lock_depth) > 0) {
461        return NULL;
462    }

因为中间的 esp-adf-libs 部分贵司只提供了库文件，并未公开源码，因此不是很明确此处为什么会出错及该如何解决，还望给出建议
