Using ALSA on Firefox instead of PulseAudio

  • 772

Since Firefox version >=52, the browser has dropped support for ALSA and depends solely on PulseAudio for sound requirements, hence rendering all sites playing audio broken on an ALSA-only system (such as Lubuntu, an official Ubuntu Flavor).

Mozilla has cited ongoing problems and maintenance issues for dropping ALSA support, as explained in the original bug report. This gives the options of either downgrading to an earlier version of Firefox (not really) or switching to a different browser.

  1. This known issue can be solved by installing apulse, the PulseAudio emulation for ALSA package.

    1. Copy the Firefox Launcher to special folder inside home

      mkdir -p ~/.local/share/applications/
cp /usr/share/applications/firefox.desktop ~/.local/share/applications/firefox.desktop`

    2. Open desktop-file with editor by

      gedit ~/.local/share/applications/firefox.desktop

    3. Modify Exec=firefox %u to Exec=/usr/bin/apulse firefox %u and save the file.

    Above will force Firefox to use the apulse library every time Firefox is launched.
