Is "Master Volume" or "Digital Volume" displayed under the volume slider ?

Master Volume and it's controlling the device's volume setting, not altering 
samples.

I've updated the device Master Volume reading by getting the dB value directly 
from the device driver.
Committed in svn #77.
If you can build Audirvana, you can check now, otherwise it'll be in rev >= 
0.6.4
