I am using centos-7 alongside unutu-20 in dual boot configuration. In centos-7 sound system as well as mic is not working but sound system is working well and good in ubuntu. I am using dual boot on Lenovo's ThinkPad.
I installed centos - 7 alongside ubnuntu-20.04. But Wifi adopter is not shown at all (blank) in centos -7 OS. However same hardware with ubuntu-20 (in dual boot mode) is working fine. Laptop is Lenovo's Thinkpad series.
