您能帮我调试为什么我的语音帽停止工作吗？它正在工作，但现在没有。不知道我做了什么使它停止了。我有两个，但现在都无法使用了，所以我确定这是软件问题。
pi@raspberrypi:~/AIY-projects-python/checkpoints $ ./check_audio.py
Playing a test sound...
Did you hear the test sound? (y/n) n
There may be a problem with your speaker. Check that it's connected
properly
Here is what I think you will ask for:
pi@raspberrypi:~/AIY-projects-python/checkpoints $ arecord -l
