'Twas brillig, and Raymond Yau at 15/06/10 00:43 did gyre and gimble:
+12dB(400%) is even larger than the software gain 150% of PA
Software gain of PA 150% = ~+11dB, so not as different as you imply.
I've explained the cubic mapping already, so please don't use arbitrary, differently calculated percentages when comparing things. It's like comparing apples to oranges.

When I changed the volume slider of the gnome sound applet ( select perference ) in Fedora 13 to maximum (i.e. PA 150% )
Seem to be bug in amixer and alsamixer
alsamixer also change to 150% but press any key change back to 100%
The volume range is only from 0 to 65536
why did alsa-lib allow alsa-pulse plugin to set it outside the range , alsamixer and amixer also display 150% ?
