stumpwm-sndioctl adds some features to StumpWM so you can control the volume using OpenBSD's sndioctl, and have it show you pretty messages as you make changes.
Add something like this to your StumpWM config:
(ql:quickload :stumpwm-sndioctl)
(define-key *top-map* (kbd "XF86AudioMute") "toggle-mute")
(define-key *top-map* (kbd "XF86AudioLowerVolume") "volume-down")
(define-key *top-map* (kbd "XF86AudioRaiseVolume") "volume-up")
The code is documented in Lisp style (i.e. self documenting), see
stumpwm-sndioctl.lisp for all the knobs you can turn.
