The Ubuntu MATE team is testing the concept of bundling snap packages in the default installation of the distribution. The developers have added a snap for the pulsemixer terminal-based volume control software and are asking users to test it. "The daily images of Ubuntu MATE 17.10 are now seeded with the pulsemixer snap. We encourage you to download the current daily image, install it and ensure pulsemixer works correctly. Pre-installing snaps by default in the desktop images was an outcome of the Ubuntu Rally that took place in New York a couple of weeks ago. Installing the pulsemixer snap by default in Ubuntu MATE 17.10 is being used as a pilot and what we learn will help the Ubuntu Desktop team with their efforts to ship snaps by default in Ubuntu 18.04. Adding pulsemixer to the default Ubuntu MATE 17.10 has not significantly affected the size of the ISO image. We chose pulsemixer because it is a small, useful application, that has never been available in the Debian or Ubuntu archives.
