Why would this be? These controls are just duplicates of others present
elsewhere in the test mixer structure. To facilitate the use of the test
mixer it is the "LOUT1 Playback Volume" etc names which should be used which
is why the patch removes the "Front Playback Volume" etc entries.
Does alsamixer/kmix assume that there will always be controls named
"Headphone Playback Volume" and "Front Playback Volume" and crash badly if
they don't exist? That seems a little odd.
