Onboard Audio

Post by winders_cruncher » 2019/11/10 15:11:25

New to Centos, I installed Centos 8 and having issues with my audio. Searched posts and for guides and am stuck. LSPCI shows the following for my onboard controller but otherwise I can't seem to get the system to recognize a driver and get the sound working. Thanks in advance for any tips.

00:1b.0 Audio device: Intel Corporation 8 Series/C220 Series Chipset High Definition Audio Controller (rev 05)
01:00.1 Audio device: NVIDIA Corporation GK106 HDMI Audio Controller (rev a1)

Further info on the LSPCI and current drivers loaded. To be more specific about the problem, in activities-sound I show no available output device.

Look at the output from aplay -L and see if any cards are recognised. If they are, find a mixer and see if the channel you're interested in is muted.

Ok, I'm assuming this means it is seeing the card properly. Any mixer you would recommend?
