Node 0x0e [Audio Mixer] wcaps 0x200101: Stereo
Connection: 3
0x11 0x12 0x13
the mixer has three connection,
node 0x11 is connected to DAC node 0x03
- HDA_CODEC_VOLUME("PCM Playback Volume", 0x11, 0x0, HDA_OUTPUT),
- HDA_CODEC_MUTE("PCM Playback Switch", 0x11, 0x0, HDA_OUTPUT),
Node 0x11 [Audio Selector] wcaps 0x30010d: Stereo Amp-Out
Amp-Out caps: ofs=0x17, nsteps=0x1f, stepsize=0x05, mute=1
Amp-Out vals: [0x97 0x97]
Connection: 1
0x03
only these two node can connect to input pins
Node 0x12 [Audio Selector] wcaps 0x30010d: Stereo Amp-Out
Amp-Out caps: ofs=0x17, nsteps=0x1f, stepsize=0x05, mute=1
Amp-Out vals: [0x97 0x97]

0x0c
Node 0x13 [Audio Selector] wcaps 0x30010d: Stereo Amp-Out
Amp-Out caps: ofs=0x17, nsteps=0x1f, stepsize=0x05, mute=1
Amp-Out vals: [0x97 0x97]

only node 0x0c has boost volume control, so Line in Playback Volume must
create at node 0x13
otherwise you won't get Mic Boost if driver create Line in Playback Volume at
node 0x12
Node 0x0c [Audio Selector] wcaps 0x30010d: Stereo Amp-Out
