I wanted to write a python program which monitors the changes in audio devices. I was suggested to use the pyudev library. The problem is I can’t identify the 3.5mm headphone jack drive/device. I found two directories but are cryptic and can’t get much out of it.

1./proc/asound
ls

card0 cards HDMI modules PCH seq version
card1 devices hwdep oss pcm timers

2./dev/snd
ls

by-path controlC1 hwC1D0 pcmC0D7p pcmC1D0c seq
controlC0 hwC0D0 pcmC0D3p pcmC0D8p pcmC1D0p timer

I would appreciate if you could help me.

And this is the code which chatgpt wrote me.

import pyudev

def monitor_headphone():
    context = pyudev.Context()
    monitor = pyudev.Monitor.from_netlink(context)
    monitor.filter_by(subsystem="sound")

    for device in iter(monitor.poll, None):
        if "HEADPHONE" in device.get("NAME", ""):
            if device.action == "add":
                print("Headphones plugged in")
            elif device.action == "remove":
                print("Headphones unplugged")




if __name__ == "__main__":
    monitor_headphone()
