[alsa-devel] ALSA Setta Mixer Values

[Alfs Kurmis]

 Hi Experts !
  How with C program i do List/Check available mixer channels  for
 ALSA snd card X,
 how to determine is it input or output ,
 how to set [and read] value(s) for any channel(s)  , [if necessary]
 [ different for Left-Right if necessary ]
 Or simplest case - How to just setta Master and PCM to given values ?
 Which include(s)--Structures--Functions must be used ?
 Is somewhere any C copy-paste example or template available ?
 Tnx for examples in advance @ all.
