Ubuntu – How to Reinstall Sound Drivers

17.10hardwarekubuntusound

I'm having some sound issues, and I believe that reinstalling or resetting my sound drivers or sound settings may solve this issue. How can I do this?
This is my list of playback devices from aplay -l

sarah@ConvergentRefuge:~$ aplay -l

EDIT 0: I tried https://askubuntu.com/a/8773/645874 but no luck. (This includes restarting the system, and not simply logging off)

  • Try this ( Open terminal: Ctrl + Alt + T):

    1. Install pavucontrol sudo apt-get install pavucontrol
    2. Install PulseAudio

      2.1 sudo apt update

      2.2 sudo apt install pulseaudio

      2.3 Now reboot your computer.

      2.4 Check if PulseAudio was installed pulseaudio --version , terminal should output something similar to mine

    pulseaudio 11.1

    1. Start AudioPulse pulseaudio --start (this doesn't open the GUI)
    2. Open the Volume Control GUI pavucontrol, this should start something similar to mine

    See the Screenshot here

    and from here set to default audio input/out by checking that green checkmark
