In Cinnamon 2.8 the sound applet will feature the following layout:
The track info and media controls are now part of a new overlay which sits on top of the cover art.
For supported players, a flat position bar is displayed underneath. This bar shows you how far you are in the song, and you can of course interact with it to go to a different position within the song.
Input controls, applications and output devices were moved to the right-click context menu.
Output devices now show their origins when multiple sound devices are detected (credits go to Cobinja for that).
Note: Styling isn’t finalized yet. There’s a bit of padding missing, the sound output devices should be better aligned in the final version, and the buttons to close and raise the player should be aligned to the right.
