UBUNTU AUDIO IN BROWSER PROBLEM / MIXER ISSUE - UBUNTU ALSA >>>

sudo add-apt-repository ppa:ubuntuhandbook1/audacity - and then:

sudo apt-get update - and then:

sudo apt-get install audacity



If yours is built-in and isn't showing up in this step, then you probably need to enable it in your BIOS. When you first reboot your computer, there's usually a key sequence listed telling you how to enter the BIOS configuration screen. >>> SEARCH

NO DEVICE SELECTION POSSIBLE UBUNTU AUDIO

TESTING NULL CLICK A SPEAKER TO TEST UBUNTU NOT SHOWING ANY SPEAKER

A standard test for speakers is to press Alt+<F2> and run

aplay /usr/share/sounds/alsa/Front_Center.wav

You should hear a voice saying "Front Center". If it doesn't play the first time you run that command, try running it again as root.

sudo aplay /usr/share/sounds/alsa/Front_Center.wav

If it still doesn't play, that means there is a problem with your configuration. If the sound plays as root, but not as a regular user, then you need to add the user to the "audio" group.

sudo addgroup <username> audio



https://askubuntu.com/questions/37589/alsa-permissions/37609#37609

DO THE TEST : sudo aplay /usr/share/sounds/alsa/Noise.wav

OR TRY sudo aplay /usr/share/sounds/alsa/*.*



SOUNDMODULES INSTALLED ?

find /lib/modules/`uname -r` | grep snd

sudo apt-get install linux-restricted-modules-`uname -r` linux-generic



6. Is the sound card physically installed and recognized by your hardware?

Open a terminal and type

lspci -v | grep -A7 -i "audio"

This should output some information about your audio hardware. An example is below.

Subsystem: Toshiba America Info Systems Device ff01

  • In pavucontrol , does vumeter move when playing ? As your sound device is the 2nd one (as seen in alsamixer) , I suppose you know that you must select it as default in devices tab with green button .

  • After that and if you have dual boot , check fastboot is disabled in windows .

  • As you have problem since update, the new alsa driver may need additional parameter :
    you can try to check your codec model :
    cat /proc/asound/card0/codec#* |grep Cod
    Then search your codec
    here or here and from the available models under this codec, add line with a similar model to your pc at the end of file:
    /etc/modprobe.d/alsa-base.conf
    F.i. if codec is ALC898 and pc is Lenovo Yoga:
    options snd-hda-intel model=lenovo-y530
    Try also
    options snd-hda-intel model=auto

Command to check codec errors at boot:

dmesg |grep codec
