Comment 53 for bug 590756

There are two demux (input source selector) , The first one in [Audio Input] node 0x14 and the second one in node 0x17

There are three [audio input] 0x14, 0x15 ,0x16 and another selector 0x18

you will need to implement input source control which allow you to select any input sources

Node 0x14 [Audio Input] wcaps 0x100d1b: Stereo Amp-In R/L
  Amp-In caps: ofs=0x4a, nsteps=0x50, stepsize=0x03, mute=1
  Amp-In vals: [0x40 0x40] [0x00 0x00] [0x4a 0x4a] [0x4a 0x4a]
  Converter: stream=0, channel=0

Node 0x17 [Audio Selector] wcaps 0x30050d: Stereo Amp-Out

Node 0x18 [Audio Selector] wcaps 0x30050d: Stereo Amp-Out
