Hello. mpv-0.18.1 has changed how softvol works [1,2] and smplayer needs to adapt. The above changes result in the following behaviour: - if softvol control is OFF in smplayer and maximum amplification is X (X>100), then OSD volume bar has maximum volume level X, i.e. there's a non-filled bar area even when volume is set to 100. IIRC the default maximum amplification value used in smplayer is 110. - if softvol control is ON in smplayer and maximum amplification is X (X>100), then changing volume to 100 via GUI volume slider actually changes it to X. OSD volume bar displays volume level correctly though. This is with smplayer-16.6.0 and mpv-0.18.1. mpv-0.18.1 will appear in tree in about a week, see bug 588492.

Please note that software volume and regular volume work properly. Only the way volume level is presented to the user is broken/inconsistent.
Same with smplayer-16.7.0.
Fixed in https://app.assembla.com/spaces/smplayer/subversion/commits/8016 Should be available in the next smplayer release after 16.7.0.
Fixed in smplayer-16.8.0, which was released about 2 weeks ago.
I can confirm this is fixed in smplayer-16.8.0.
