No sound after forced reboot

So, the system was looped. I mean, no response and just freezes, so I rebooted it forcefully, and now I have no sound.

Output of dmesg | grep snd

Do not hard reset your Linux computer, as that may break things. Instead, enable and use the Magic SysRq key to reboot a frozen system in a safe and graceful way.

Of course, now it is too late for this, but it’s good to know such things for the future.
