The internal microphone doesn’t work on my Dell Inspiron 14 7440 running ubuntu, though it is recognized on windows and I remember it working before I reinstalled the ubuntu system. When I open sound settings, the app doesn’t recognize the internal microphone: Screenshot
I ran alsamixer (newest version) in the terminal and didn’t see the internal microphone, this is what it looked like: This screenshot shows all devices listed in alsamixer.)
I also looked at pavucontrol and the app shows the internal microphone as “unplugged”: Screenshot
How can I get the microphone working?
idk the headset thing is often hardware controlled, so it shouldn’t be a problem after reboot, but if you want to be sure plug one in when it’s off and remove it when on. that should trigger the unplug software event, if there is any.
i’m out if ideas. good luck!
I tried plugging in a headset and plugging it out. When I plugged it in 2 microphones showed up, one called “headset microphone” and the other just called “microphone”, screenshot:
But when I unplugged the headset both microphones are gone, does it mean that my laptop recognizes its internal microphone when a headset is plugged in? Also when I switch to the one just called “microphone”, speaking to the headset microphone doesn’t make the bar move as much as patting the laptop, so the “microphone” should be the internal microphone.
wow, that is some progress. maybe check out what your system does when you do that, using kernel log (dmesg?), udev log and systemd log. but i can’t help you past this point it’s too weird.
