MX Linux Forum

So have you contacted Mint?
That would be the logical thing to do.

That fixed it. One tap of the m key.

Oh I see tapping the m key changes the value.

I opened alsamixer in the terminal and it shows mm which I read somewhere is muted.
i do not know how to change it yet, more research.

Looking at pulse audio control it shows line out plugged in but speakers unavailable.
How to make them available again?

Thanks for your reply. Actually before I saw your reply looked at QSI and realised it is in fact a software problem and not a hardware issue. I was in MX19 when it broke so just now booted in MX 21 and sound works there. it also works when I boot my last MX19 snapshot. I wonder if I could find pulse...

Has anybody heard of this happening?
Just wondering. I heard sound for a second and then it went dead.

OK I found a solution that worked.
I ran apt-get update --allow-releaseinfo-change
in the terminal.
I then closed the terminal and ran the green mx-update and it worked.
That fixed the debian buster update problem.
I am going to mark this solved.
Thanks for all your help.

Yep that fixed the google repo.

By the way, this is an old Lenovo M-58 SFF that I bought in 2013. I rarely update the MX-19 on this one because I mostly use windows on it for genealogy.
