After installing the system updates via AppCenter the speakers do not sound.
Unfortunately this solution is not valid today.
Is there any chance to overcome this issue?
Because of I'd tried it before and realized that the system updates cause some problem on my laptop, after fresh Elementary OS installing, I use my laptop 3 days without any issue.
Then I got the system updates again. Now the speakers do not sound.
Dummy Output seems on the sound settings page.
Is there any way to overcome this issue?
Edit: My soundcard manufacturer is Realtek. But I cannot find model number on Elementary OS or BIOS screen.
