I just installed Ubuntu 20.04 on my laptop which is a bit outdated:
- CPU: Intel Core i5 CPU M 480 @ 2.67GHz
- RAM: 4GB
- Video card: GeForce GT 420M
- Audio: GF108 High Definition Audio Controller NVIDIA
and Audio 5 Series/3400 Series Chipset High Definition Audio
Overall the system is working fine, but I'm having a big issue with HDMI Audio. The display on HDMI works just perfectly, but the audio is not working at all.
I tried lots of solutions here on Ask Ubuntu, but the problem remains. Some of the solutions I tried are located in the following links:
Also I've downloaded Ubuntu 20.04 iso again and reinstalled the system, but it doesn't work.
HDMI worked perfectly when I used Windows 10 before replacing it with Ubuntu.
When I run
aplay -l I have these results:
When I run
lspci I have these results:
In the Settings -> Sound -> Output -> Output Device I have just two options to choose from:
- Digital Output(S/PDIF)-Built-in-Audio
On Pulseaudio > Configuration it shows:
GF108 High Definition Audio Controller
And in both of them all the options with HDMI are displayed with (unplugged)(unavailable).
Finally, the sound just works in my laptop, if I connect HDMI cable it display correctly but the sound keeps on my laptop.
