Many users experience the graphic cards driver issues. One of the issue is installing drivers for Hybrid Graphics cards. Well if you get it installed one time correctly you will be able to do it again.

Now other problem is when you upgrade the drivers. Many users reported that they have no sound after installing new graphics card drivers. So, we will tell you the small secret how to fix it easy and fast.

Fixing No Sound after Installing New Graphics Card Drivers

The firs thing is to check if your audio drivers are installed. Note that it is not necessary to install any audio drivers as Ubuntu install the automatically.

Step 1. Open the terminal and type the following command and hit enter:

ubuntu-bug audio

You should get the following results:

You seem to have configured PulseAudio
to use the "pci-0000_05_00.1" card,
while you want output from "NFORCE -
NVidia CK804".

Basically anyway you should have configured audio drivers.

Step 2. Make sure that the hardware used in “Sound Preferences” is the correct one, as it can be that instead if your audio boxes there would be another hardware used.

To check it, go to: System > Preferences > Sound, then select the Hardware tab and to choose a different device from the list click on: Choose a device to configure.

Note: If everything looks right, better do not change it, and proceed to the next step.

Step 3. One of the main reasons is the BIOS that makes trouble to your audio. From BIOS there is “Enable onboard Audio” which is set to “AUTO“. Which means if there is no audio output on it for HDMI, the onboard sound will be automatically “Disabled“.

To fix it, boot into BIOS mode when your computer is starting up. Then find in the BIOS the setting “Enable on-board Audio”, on other BIOS it can be AC97, and switch it from auto to “Enabled“, then remember to Save & Exit the BIOS.

Here are the screenshots how it looks in different BIOS versions:
