2011-10-04ALSA: hda - Add documentation for codec specific mixer controls of Analog codecsRaymond Yau
* Channel Mode This is an enum control to change the surround-channel setup, appears only when the surround channels are available. It gives the number of channels to be used, "2ch", "4ch" abd "6ch". According to the configuration, this also controls the jack-retasking of multi-I/O jacks. * Independent HP When this enum control is enabled, the headphone output is routed from an individual stream (the third PCM such as hw:0,2) instead of the primary stream.
