Unbearable Microphone background noise (warning, earrape)

So I got my arch setup but my microphone sounds like this https://vocaroo.com/i/s1YR5GcqJw00 if i plug the headset+microphone in the other jacks it sounds the same. I tried and the problem is not with the microphone.

It's either the pc or my arch setup. How do I fix this?  I tried changing from 44.1khz to 48khz and back again

I tried pulseaudio troubleshooting (microphone) and also alsa troubleshooting (microphone).

I desperately need to be able to record video and audio with obs but this quality is unacceptable and it's due to my arch settings probably.

Can anyone help please?

Re: Unbearable Microphone background noise (warning, earrape)

Post the contents of the files you've adjusted so far, what are you using to record? During recording, what is the output of 

pacmd list-sources
pacmd list-source-outputs
arecord -lL
amixer -c0 #Use correct index from arecord -l here
sudo fuser -v /dev/snd/*

where did you verify that your microphone works alright, is it possible to acquire sampling rate information from a working system?

Re: Unbearable Microphone background noise (warning, earrape)

From the PulseAudio Troubleshooting page,( https://wiki.archlinux.org/index.php/Pu … Microphone ) I've tried the Static noise in microphone recording solution.

I edited /etc/pulse/daemon.conf . I found out that thie highest suppported sample rate by my sound card is 48000 hertz.  The sample rate in daemon.conf was set to 44.1khz. so I changed it to 48khz and back but no improvement.

I recorded using arecord -f cd -d 10 test-mic.wav but I need to record with obs and there it sounds even worse.

I didn't know how to copy paste from my terminal (simple terminal) so I uploaded my daemon.conf here https://ufile.io/xclyiuwx



Second I tried from the ALSA troubleshooting guide ( https://wiki.archlinux.org/index.php/Ad … Microphone ) 

The Crackling microphone solution, I created a file /etc/modprobe.d/modprobe.conf with the content     options snd-hda-intel model=MODEL position_fix=3


So yeah basically I don't know exactly what's wrong and which solution to apply.

I tested the headphones+microphone on my mom's laptop with windows 10 and it worked impecably. I will try and follow up with a sample rate if I find on google how to find the sample rate in windows 10.

Now I will start the recording with obs and run your commands and tell you the output.

Re: Unbearable Microphone background noise (warning, earrape)

Please use [ code ] [ /code ] tags without spaces for posting outputs in the future. As for properly copying from a terminal: https://wiki.archlinux.org/index.php/Co … a_terminal (if the following doesn't fix it repost full outputs of these truncated pacmd commands)

Your Mic Boost and your general volume is at full blast which makes this result unsurprising. Tone that to reasonable levels: 

 amixer -c0 set 'Rear Mic Boost',0 0
amixer -c0 set 'Capture',0 70%,70%
pactl set-source-volume alsa_input.pci-0000_00_1b.0.analog-input-rear-mic 70%
pactl set-source-output-volume 1 70% #This "1" here is the index of your recording application, it can change, doublecheck while recording with pacmd list-source-outputs

In general you will probably want to set up and use a GUI for this like pavucontrol which would easily show you that your volumes are configured too loudly.

Also if you literally copied that string into  /etc/modprobe.d/modprobe.conf  that will at best not do anything at worst have bad implications so you will want to remove that file.

The rest looks alright apart from the overdriven volumes, i.e. it's unlikely that the sampling rate has any negative effect here..

Re: Unbearable Microphone background noise (warning, earrape)

I reduced the volume in pavucontrol. That is not the main problem here.  https://vocaroo.com/i/s0npQngbN2K7 if you check now, the volume is ok but there is still that annoying background noise, that is otherwise not present on the laptop with windows. I will enter those commands while recording and share with you the output fully.

Re: Unbearable Microphone background noise (warning, earrape)

Your OBS stream is still set to 150% that is nearly always too big of a value, tone that down.

Re: Unbearable Microphone background noise (warning, earrape)

although much better than before, it still has the background noise. where do I set it to 100% from 150%? I may have already done that in pavucontrol. here is a recording. what else can be done? the problem may be with the pc itself and not the software itself, but if there is anything else I can do I'd be glad to hear your recommendation.

Re: Unbearable Microphone background noise (warning, earrape)

Is that an Azalia chipset, by any chance? I had to follow these instructions to get rid of horrible static noise I got with my Realtek on-board card (ALC889A).

Re: Unbearable Microphone background noise (warning, earrape)

My pc is a dell optiplex 990. where do I find the chipset name/serial no. ? and how do i then reload my modules (at the end "then reload your modules") https://wiki.archlinux.org/index.php/Pu … a_chipsets

Re: Unbearable Microphone background noise (warning, earrape)

You could unload/reload the kernel module(s) with rmmod/insmod, respectively, but a reboot will definitely take care of it (and is probably the safer approach).

Option 2 did the trick for me, btw. So I have

options snd-hda-intel position_fix=2

in '/etc/modprobe.d/azalia-microphone.conf' (file name doesn't really matter as long as it ends with *.conf).

Re: Unbearable Microphone background noise (warning, earrape)

Re: Unbearable Microphone background noise (warning, earrape)

I don't think there's any harm in trying; there are only 4 possible values, after all. If it doesn't work, just delete the file and continue to look for another solution.

Re: Unbearable Microphone background noise (warning, earrape)

Let's try something simple first

parec  -d=alsa_input.pci-0000_00_1b.0.analog-stereo --volume=32768 --file-format=wav testrecording.wav

if that works correctly, then the issue is still the volume, if that doesn't work correctly then one thing you can try is hooking a noise  canceller in between: https://wiki.archlinux.org/index.php/Pu … ncellation

FWIW though I don't use it myself some google results suggest OBS should have the ability to configure something similar in the microphone filters, you might prefer using that.
