[SOLVED] ALSA and PulseAudio miss configuration

Hello and good night, this is the first time i did not find a solution for my "problem" online so i will try it here.

The problem is probably the configuration on this systems, there are 2 symptoms i'm having:
1. I can't use my headset microphone, it is a jack headset, when i select it and do an record i just hear some high pitch noise and the internal audio output.
2. Programs that record internal audio like obs do not get any output.

This started happening some time ago, i used to use it without any problem, i don't know if it was some update i did or any miss edit on configuration files.

Here are some information:
My asoundrc:

# Use PulseAudio by default
pcm.!default {
  type pulse
  fallback "sysdefault"
  hint {
    show on
    description "Default ALSA Output (currently PulseAudio Sound Server)"
  }
}

ctl.!default {
  type pulse
  fallback "sysdefault"
}

Output of aplay -l (with headset connected):

**** List of PLAYBACK Hardware Devices ****

  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 10: HDMI 4 [HDMI 4]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Output of arecord -l (also with headset connected):

**** List of CAPTURE Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC3254 Analog [ALC3254 Analog]
  Subdevices: 0/1

Any help will be appreciated, thanks in advance.

Please use [ code ] rather than [ quote ] tags for outputs

During a problematic recording, what's your output for 

amixer -c0

Re: [SOLVED] ALSA and PulseAudio miss configuration

You aren't recording in that output or at least not via pulseaudio, what are you using to test the recording? But regarding the issue with internal audio recording...

Re: [SOLVED] ALSA and PulseAudio miss configuration

When i tried to record with arecord it said that the device was busy so i used obs but i don't know what audio system it use.

Anyway this unmute seens to have fixed all the problems i was having, my input looks nice and software that records my internal output are working too!!

May i ask what does this source means or any point in the direction of learning it better?

Thank you for your help!

Re: [SOLVED] ALSA and PulseAudio miss configuration

pulseaudio sources are input/recording devices, like microphones.

A monitor source is a "microphone input/recording" "device" (in this case this isn't a device that physically exists, but pulse allocates one for each audio output card you have) that does loop  all the output you play on the output card into a recordable device. This should not have an effect on your actual real microphone so you might have changed something else to fix that.

Anyways if this is fixed, please mark it as [SOLVED] by editing the topic title.
