set-volume/mute randomly gets stuck on values
Attempting to set-volume or set-mute with WP randomly silently fails to modify the desired value. If it failed once, all subsequent attempts at the same operation (absolute or relative modification for volume alike) will also fail, until a different operation is tried - whence the previously failed operation may or may not work again.
E.g.
set-volume 0.05+ # works
set-volume 0.05+ # works
set-volume 0.05+ # doesn't work and never will
# ...
set-volume 0.10+ # works
set-volume 0.05+ # works again
