My motherboard is a MSI 760GM-E5I (FX) which uses a Realtec audio chipset ALC888S/ALC889. Sound worked fine on the previous 14.04 version, but hasn't worked since the upgrade. System Settings says I'm configured for "Digital Output (S/PDIF) - Built-In Audio" - "Digital Stereo (IEC958) Output" but doing the speaker test yields nothing.

I tried

sudo alsa force-reload

to no avail. Also,

sudo apt-get remove --purge alsa-base pulseaudio

followed by

sudo apt-get install alsa-base pulseaudio


sudo alsa force-reload

again. Still no joy.

The Realtec site doesn't offer Linux drivers for this product.

  • in case sound would work you would probably have a sort of trouble like it happened already with this malware program "animal" in earlier times in 70ies (80ies) + be patient + and this is typic for things with mouses since the 70ies no matter which system + – dschinn1001 May 14 '15 at 1:29

Open the terminal and edit speech-dispatcher file by using the following command:

sudo gedit /etc/default/speech-dispatcher

In here, change RUN=yes to RUN=no

Reboot and test

    I did use gedit to look at speech-dispatcher but found that RUN=no was already set. – RhoTheta May 15 '15 at 5:03
