Amp Capabilities settings :

[Baio1977]

I'm trying to create a layout with full functions for my X1 Tablet 3rd Gen, after several tests this is what I understood:

Dump info Node 2 :

[Audio Output] wcaps 0x41d: Stereo Amp-Out
Control: name="Front Playback Volume", index=0, device=0
ControlAmp: chs=3, dir=Out, idx=0, ofs=0
Device: name="ALC295 Analog", type="Audio", device=0
Amp-Out caps: ofs=0x57, nsteps=0x57, stepsize=0x02, mute=0
Amp-Out vals: [0x57 0x57]
Converter: stream=0, channel=0
PCM:
rates [0x40]: 48000
bits [0xe]: 16 20 24
formats [0x1]: PCM
Power states: D0 D1 D2 D3 EPSS
Power: setting=D0, actual=D0

How I set the Platforms69.xml since the node is OUT only

Dump info Node 8:

[Audio Input] wcaps 0x10051b: Stereo Amp-In
Control: name="Capture Volume", index=0, device=0
ControlAmp: chs=3, dir=In, idx=0, ofs=0
Control: name="Capture Switch", index=0, device=0
ControlAmp: chs=3, dir=In, idx=0, ofs=0
Device: name="ALC295 Analog", type="Audio", device=0
Amp-In caps: ofs=0x17, nsteps=0x3f, stepsize=0x02, mute=1
Amp-In vals: [0x3f 0x3f]
Converter: stream=0, channel=0
SDI-Select: 0
PCM:
rates [0x560]: 44100 48000 96000 192000
bits [0xe]: 16 20 24
formats [0x1]: PCM
Power states: D0 D1 D2 D3 EPSS
Power: setting=D0, actual=D0
Connection: 1
0x23

Same approach for input nodes

Dump info Node 27:

[Pin Complex] wcaps 0x40058f: Stereo Amp-In Amp-Out
Control: name="Bass Speaker Playback Switch", index=0, device=0
ControlAmp: chs=3, dir=Out, idx=0, ofs=0
Amp-In caps: ofs=0x00, nsteps=0x03, stepsize=0x27, mute=0
Amp-In vals: [0x00 0x00]
Amp-Out caps: ofs=0x00, nsteps=0x00, stepsize=0x00, mute=1
Amp-Out vals: [0x80 0x80]
Pincap 0x00013734: IN OUT EAPD Detect
Vref caps: HIZ 50 GRD 80 100
EAPD 0x2: EAPD
Pin Default 0x90170150: [Fixed] Speaker at Int N/A
Conn = Analog, Color = Unknown
DefAssociation = 0x5, Sequence = 0x0
Misc = NO_PRESENCE
Pin-ctls: 0x40: OUT VREF_HIZ
Unsolicited: tag=00, enabled=0
Power states: D0 D1 D2 D3 EPSS
Power: setting=D0, actual=D0
Connection: 2
0x02 0x03*

This node 27 being IN\OUT instead I set it like this

Can we define this configuration as correct???

The result of my tests is fully functional, I improved the quality of the sounds in Output\Input and reduced noises\background disturbances.

But the work is still very long.........
