if I make a customised device "test" with softvol plugin with name "P
Playback Volume" in .asounrd
aplay -D test.wav
alsamixer -c0 show the "P" control and volume change as expected
Then change the name from "P Playback Volume" to "Q Playack Volume" and play
audio through device "test" again
alsamixer -c0 show both "P" and "Q" controls
"P" control can go up/down with no effect of course
but "Q" stayed at 100%
Is this a bug ?
