My bad.
So the original question is about no sound after installin Mint on 2 different setups, a notebook and a desktop.
This goes to @okkadiroglu :
On both systems do this please:
Boot up the computer as usual, login as usual.
Press ctrl-alt-T, that’s thequickest way of opening a terminal.
Copy the command:
inxi -Fxmz
from here via selecting it, and pressing ctrl-c (copy).
Now in the treminal paste the command via shift-ctrl-V (paste) and press [Enter].
That executes the command.
The command will print out informations about your computer.
Select the text in the terminal the way you would do it in any other window.
Note, that the info may be longer than what you see in the terminal, so when selecting, drag the mouse upwards until the command itself is selected too, this may involve some scrolling upwards.
Now press shift-ctrl-C (this copies stuff from terminal to clipboard).
Coma back to here, and paste it into your answer, for reference I paste here my inxi output:

Highlight here the newly pasted information, and press this button:

That makes it formatted as “code”, so it will be better readable.
Do the same with aplay -l.

Repeat this on the other computer too.
These commands do no harm to your system, they don’t change anything. They just give some information for us to look at, so we can think about it.
There’s no guarantee we can help, and later we may ask for other informations via commands the same way.
