[20B00050GE, Realtek ALC269VC, Speaker, Internal] No sound at all (The speakers had worked before with 14.04 but suddenly they do not anymore)

[Marko Grubi]

I do not know which update has caused the problem. The speakers had worked already with 14.04 but since a few days there is no sound anymore.

Headphones work correctly.

I have a Thinkpad S531 Laptop which is certified to work with Ubuntu.

Thanks!

Is this an abandoned bug?
