1 x Headphone-out jack (Audio-in Combo)

does it mean that headphone jack can be retasked as mic jack or line in jack ?

[Raymond (superquad-vortex2)]

when available is unknown , the analog input port which exclude mic. line in has higher priority than the internal mic port

ports:
  analog-input: Analog Input (priority 10000, available: unknown)
   properties:

  analog-input-microphone: Microphone (priority 8700, available: unknown)

please trey audacity to record stereo instead of mono and check whether the left and right channel are out of phase

I think it can do both at the same time, like on smartphones (ie.

It records stereo by default I believe, as the screenshot shows two channels.

[Raymond (superquad-vortex2)]

do you mean the recorded singal is too low ?

use alsamixer to make sure that pa does not chane the mic boost or mute the capture volume

can you record from hw:0,0 instead of default ?

there is only internal mic at node 0x12 and there is no mic jack pin complex

no int mic phantom jack kcontrol and only mic boost volume

analog-input-microphone: Microphone (priority 8700, available: unknown)

  Amp-In caps: ofs=0x00, nsteps=0x03, stepsize=0x2f, mute=0
  Amp-In vals: [0x03 0x03]

post pulseaudio log to find out why the fallback port is added

I have attached records as ogg, as well as Sound settings and
alsamixer screenshots, i'm litteraly yelling at the computer but it
only recorded some frying.

It looks like nothing is messing with alsamixer.

In audacity -> Edit -> Preferences -> Devices -> Recording, the only
two choices are: "default" and "pulse". I tried both and the result is
the same.

So it's recording with a mic that does not physically exist ? That's
interresting xD

Logged pulseaudio while recording with audacity, attached as pulseverbose.log.

I have such a file in
/usr/share/pulseaudio/alsa-mixer/paths/analog-input.conf, is there
anything you want me to do with it ?

Thanks for your support.
