Embodiments are provided for controlling playback volumes of a group of one or more playback zones in a network media system via a user interface provided on a touch screen display. For instance, touch inputs may be provided to the user interface via the touch screen to move a volume indicator along a graphical representation of a volume scale on the user interface to adjust a particular playback volume level of a playback zone or the group of the one or more playback zones. Further, touch inputs such as a dwell touch input or a swipe touch input may be configured to cause the particular playback volume level to be applied to other playback zones in the network media system, such that each playback zone the playback volume level is applied to has a respective playback volume level matching, or substantially matching the particular playback volume level.
