Bug Description

Lenovo ThinkBook 14s G2
1. Boot to windows (ah yes, I'm still using windows for something that's not fully supported by Ubuntu).
2. Restart, boot to Ubuntu.
3. Got no sound, except just a cool "sssssssshreck" sound when it has to be a sound, only a short sound although I'm about to play a long audio. Probably each time playback is activated the short "sssssssshreck" sound is produced.
4. Restart, boot to Ubuntu again.
5. It is not fixed yet.

However the playback works if I fully turn the computer off and then turn it on again, instead of restarting.

Additional bugs, probably related:
1. When the sound works, there is a little noise that can be heard if there's a silent audio playing.
2. When increasing/decreasing volume by using multimedia keys, sometimes it continuously increases/decreases as if the button is kept pressed although I just press it once and release it immediately.
