Sound sometimes works, sometimes doesn't LM14 Cinnamon 32

[Tit]

Hello!

Can anyone tell me why sound sometimes works perfectly in Linux Mint, other times nothing (still, the volume indicators indicate activity, but the speakers don't produce any sound). Rebooting always fixes the issue.

I have commented the line:
#load-module module-suspend-on-idle
in /etc/pulse/default.pa with no success.

Any ideas?
