Hi!I have Debian 11 64 bit installed on my machine.I was testing timeshift restore which went successfully.However,I have lost both speaker and microphone functionality on my Debian so when I play a video there is no sound output.

When I check my sound settings,screenshot is as below



When I enter alsamixer command the output is as below when I press F5 to capture all statistics



When I enter pavucontrol command,output for Input and Output are as below just showing Dummy





Other command outputs are as below

I decided to do a factory reset of BIOS Security and now I am ok.
