    No input device under sound settings, Microphone not detected

    Hello Everyone,


    I recently came across an issue while I was about to join a google meet my microphone was not detected by google meet for some reason, So I went into the sound settings and it showed no input device I searched for the solution to the problem but nothing seemed to work. If you find any solution please share it with me I'll be grateful.


    my laptop is HP eg 2035 tu

    I ran some commands to check for audio config/details here is the output

    usually related to pulse audio and it not talking to ALSA in most cases.
    Install pulse audio volume control, that should allow easy config;

    sudo apt install pavucontrol

    Open a terminal and first install ALSA utilities, and then run the set up;

    sudo
    apt install alsa-utils

    alsamixer


    you will then get a menu to select devices for ALSA that should allow you to choose the correct input.

    you may need to reboot after setting ALSA for pulse audio to pick it up.
