So I recently changed from Windows to Ubuntu and I am having sound issues. I don't have any sound at all. I am using NVidia Drivers so I know that may cause issues but I want to know if there is any solution. My alsamixer looks like this:

alsamixer

Also if I do aplay -l I get:

**** List of PLAYBACK Hardware Devices ****
card 0: NVidia [HDA NVidia], device 3: Generic Digital [Generic Digital]
Subdevices: 1/1
Subdevice #0: subdevice #0

I cant change the volume of S/PDIF and in alsamixer when I press F6 I only get the Nvidia card. Please help.

EDIT: When I use lspci -vnn | grep -iA4 audio I get:

I had the exact problem a couple weeks ago!!

Here's a thread I started with my problem as well, and a solution bellow that I found after intensive work

Hope it fixes yours as well.

Seems like you have wrong driver loaded Kernel driver in use: sof-audio-pci

Try to override it to snd_hda_intel with this command:

sudo driverctl list-devices

You should see your audio device as 0000:1028:0949 you can also shorten the search if you write the loaded driver to be sure:

sudo driverctl list-devices | grep sof-audio-pci

Then replace loaded driver on device to snd_hda_intel

sudo driverctl set-override 0000:1028:0949 snd_hda_intel

Now you should be fine, type killall pulseaudio to refresh it or reboot the system to take effect.

If you don't have driverctl utility install it:

sudo apt install driverctl
