Lenovo E14 Gen3 hardware mute button will not unmute

Hi, I’ve just installed Manjaro 21.2.2 on my Lenovo E14 Gen3 laptop. The hardware mute button will not unmute, and I’d like it to work for mute and unmute.

I checked the AlsaMixer. When I press the mute button, the Master and Speaker are muted, but when I press the mute button again, only the Master is unmuted.

How can I fix this? Please let me know.
