In order to standardise various separate volume UIs, upstream PulseAudio has made a new define available for the recommended maximum volume to show in UIs. This volume was chosen to be similar to the value currently employed in gvc but also be based on dB values rather than a multiple of PA_VOLUME_NORM. The 150% value previously used mapped to +10.57dB with the current cubic volume mapping. In the interests of sanity, and with a tip of the hat to Spinal Tap, we decreed that the value should be +11dB. This is approx 153% which is doesn't really change the visual look of GVC. I will also be recommending other volume controls use this new value so everyone can use the mixer they want. This one goes up to 11. :) References: https://tango.0pointer.de/pipermail/pulseaudio-discuss/2010-April/006945.html https://tango.0pointer.de/pipermail/pulseaudio-discuss/2010-April/006950.html http://en.wikipedia.org/wiki/Up_to_eleven https://bugzilla.gnome.org/show_bug.cgi?id=644292
