PulseAudio volume control

[Kelvin]

Hi ,
I am a new SparkyLinux user.
My OS version is V5.11(LXQt).
I found that the app "PulseAudio volume control" is no good . When I gently adjust the volume control (very sensitive). The sound level become very strong. Please give me a suggestion to solve the problem. Thanks!

Try pavucontrol or alsamixer in the terminal.
