语音识别中的alsa问题（Python 3）

我的ubuntu20上有声音，我可以播放任何音频；但问题是当我使用语音识别时，alsa不能正常工作。我在windows中使用了语音识别，这很痛苦，但很有效。我已经安装了pyaudio，。。。所以这不是图书馆的问题

我已经做了：

   1.Reinstalling alsa and pulseAudio.

   2.Checking which program is using sound card.

   3.Trying to specific device to be used in Microphone().

当我使用：python -c "import pyaudio;audio=pyaudio.PyAudio();print([audio.get_device_info_by_index(i) for i in range(audio.get_device_count())])"

返回：

我使用的是VS代码，这可能是一个bug。问题是我怎样才能摆脱它

嘿，伙计们，我用sudo apt-get install pavucontrol安装了voice control。在Thermanal中使用pavucontrol运行它。在语音控制中，将录音设备置于0。我的笔记本电脑内置了麦克风，我知道如何找到它
