Fixes:
--------

* renamed capture controls
New features:
------------------
* analog input switch (line-in/mic)
* optional ak4114 based MI/ODI/O card detection & support: IEC958 input,
  digital input switch (toslink/coax)
Unresolved issues
-----------------------
* Analog and digital input enums are listed on playback panel of alsamixer,
