SOLVED - Audio not working in CentOS - New Installation

Post by kalyanfromusa » 2021/07/27 02:21:59

Hello all,
I have installed CENTOS 8 in my machine in dual mode.(Already have windows 10). Seems Audio is not working in Centos 8. I checked the settings/sound and it all looks good to me. The audio works fine in my windows. Only issue is with Centos 8. Any help in fixing this is appreciated. Thanks.

Most likely this:
00:1f.3 Audio device [0403]: Intel Corporation Sunrise Point-LP HD Audio [8086:9d71] (rev 21)

Find out which module/driver it needs and see if it's loaded with this command:
lsmod

Wierd, but it just solved on its own. These are steps happened.

Every sequence of Steps before it starting to work:
i. An youtube video was playing with no sound. (I forgot to close it)
ii. It went into screensaver mode and sound came suddenly.
iii. When I interupted the screensaver mode, no sound again.
iv. I restarted now, with install updates and restart option
v. After restart no luck and no sound
vi. I tried (first time) with a headphone and sound from headphone is working.
vii. I removed the headphone and sound from speaker starting working.

Wierd, but it is what it is. Thanks for your help. :)
