"before upgrading, laptop has issue with sound."

Did you mean "before upgrading, laptop has NO issue with sound."

Also what was the version before the upgrade?

[cehkop]

It was about the speaker. The laptop has several dynamics, but before the upgrade, it seems only one worked and the sound was flat (same time on Windows, it was good). After upgrade, the speaker sounds good, but the microphone doesn't work.

Before the upgrade, it was Ubuntu 23.10, with kernel 6.5 if I remember correctly
