    Initially the speakers and earphones were working properly but the mic wasn't. However, I ruined everything in order to fix mic input.
    PLEASE HELP!!!

    What exactly did you do? At least give links.

    Also, there's a beter way to get info:
    Code:
    sudo alsa-info
    Upload the info and give us the link.

    Had the same issue, I just did:
    sudo killall timidity
    Then the sound came back.
    But after reboot, there is no sound again.
    Then I figured out the proper way of disabling timidity:
    sudo systemctl stop timidity.service
    sudo systemctl disable timidity.service
