Describe the bug

I used a driver-free USB microphone to do some audio activity detection, such as automatically detecting the audio cutoff point, but some unexpected errors occurred, as shown below:

Please start speaking...
Recording stopped.

Steps to reproduce the behaviour

This is the code that reproduces the problem I encountered above：

import speech_recognition as sr

r = sr.Recognizer()
mic = sr.Microphone()

with mic as source:
    r.adjust_for_ambient_noise(source)  # Adjust the microphone to capture ambient noise
    print("Please start speaking...")
    audio = r.listen(source)
    print("Recording stopped.")

I looked for some solutions, such as editing the asound.conf file under /etc, but there is no asound.conf file under /etc. Then I created a .asoundrc file in my user directory, and the content of the file is as follows:

pcm.!default {
    type plug
    slave.pcm {
        type bluealsa
        interface "hci0"           
        device "04:CB:88:B9:4A:EC" 
        profile "a2dp"
    }
    hint {
        show on
        description "JBL Flip Essential"
    }
}

ctl.!default {
    type bluealsa
}

pcm.usbmicrophone {
    type hw
    card 2
    device 0
}

ctl.usbmicrophone {
    type hw
    card 2
}

pcm.dmixer {
    type dmix
    ipc_key 1024
    ipc_perm 0666
    slave {
        pcm "usbmicrophone"
        rate 48000
        channels 2
        period_size 1024
        buffer_size 4096
    }
}

pcm.dsnooper {
    type dsnoop
    ipc_key 1024
    slave {
        pcm "usbmicrophone"
        rate 48000
        channels 2
        period_size 1024
        buffer_size 4096
    }
}

pcm.duplex {
    type asym
    playback.pcm "dmixer"
    capture.pcm "dsnooper"
}

pcm.!default {
    type plug
    slave.pcm "duplex"
}

But it still can't solve the above problems

You would be better off creating a post on the forum.
This sounds more like configuration issue than a kernel bug, and the forum may have some users who have done something similar.

Try the forum - this doesn't sound like a link kernel bug.
