Colin Guthrie a9555f52d0 sound: Use upstream value for amplified volume 
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. :)
