I have attached patch for envy24control because after update from James
Tappin i have had problems with the mixer and patchbay.
SPDIF inputs and outputs was duplicated.
* HW In level meters were broken
* The last PCM Out meter was broken
* S/PDIF channels can now be controlled with -s, --spdif
* The Patchbay/Router and Analog Volume tabs now accurately reflect the
number of requested channels in all cases.
