Sound very low on Win 11

The sound is low and choppy, I can't hear what other people say even though the volume is max. I tried to test my speaker in the setting audio, but it is still small. Sometimes Zoom pops up this notification "Low system resources may affect your audio quality...", but I only open Zoom? This only happens in Zoom, other applications sound is still normal, proving that my speaker is fine.
My laptop is ASUS with Windows 11

Who can help meeeee
