[Microphone[Echo in the background, some devices are not visible

[Domin_PL]

Hello guys,
I've recently reinstalled Linux Mint and changed to Cinnamon desktop. On Tara I used to have so many microphone issues, which I still have.
According to my issue: I got 3 microphones: 1 is Apple Headphones (it should work, shouldn't it?), and 2 are normal, analog which don't work to me, even though one of them is brand new. The only difference between Apple headphones and those 2 microphones is that, Apple headphones are 3 pins when microphones are 2 pins. Heading step back to my problem, I've already added following lines to my default.pa file in /etc/pulse:

Code: Select all

load-module module-echo-cancel source_name=noechosource sink_name=noechosink
set-default-source noechosource
set-default-sink noechosink

it reduced my echo level, but echo still exists. Sample record from Apple headphones: https://drive.google.com/file/d/1_UQhvN ... sp=sharing
I don't use my microphones for one reason - they are not recognised in the system, when I try to record it is as they were not connected, maybe it's hardware problem, I don't know. Current input volume is set up for 45%. Not sure what am I supposed to do more.
So, do you have any suggestions how to remove this echo from the background?

I'm providing outputs from some codes, how am I to hide them to don't make this post too long, something like click to show/hide?
Thanks in advance!

if you don't have experience with audio hardware i would eliminate some. 3 micorphones is bound to have conflicts. is your noecho running?
pactl list | grep -A2 'Source #' | grep 'Name: ' | cut -d" " -f2

Hi Domin_PL.

While trytip helps with the echo issue, I'll take a stab at the unrecognized mics.

First I must say, I'm assuming by 2 vs 3 pins, you're referring to the rings on the 3.5mm plug. This shouldn't have any effect on your issue. I'm also going to assume for the moment that the other mics are microphones only and not headsets. If I'm wrong, please correct me.

Stand-alone mics are plugged into a different port than headsets, so start with that check. Headsets into headphone port, mics into mic port.

Install and run PulseAudio Volume Control and on the Configuration tab, make sure the Profile for your Built-in sound card is set to Analog Stereo Duplex. Then look on the Input Devices tab to see if the mic shows up.

If all this is of no help, paste back the output of aplay -l please. Use the code button like you did with your default.pa edit.

Good luck.

Allright, following up to your answers:
I have a laptop, so that I have only one minijack port. Does it mean then, I can only plug-in headset, not a microphone only? If I wanted to plug-in a microphone I need to have one which uses USB port as input port?

My built-in card is set to Analog Stereo Duplex, as mentioned. Noecho is running, there is huge difference between noecho provile vs default profile (with noecho disabled)

Sorry. For some reason I thought you were using a desktop. A USB mic should work fine, but I believe yours should as well. When one of the unrecognized mics are plugged in, does anything show on the Input Devices tab? In case your audio chip needs a workaround for microphone use, I'll need to see the output of aplay -l to be able to look it up.

[Domin_PL]

Unfortunately it doesn't show me anything when microphone is plugged in. Then it does use internal one.

here's aplay -l output:

Code: Select all

$ aplay -l

i removed the noecho from my profile. it worked very good recording myself, but when using skype there was major microphone sound issues with clicks and bumps as if speaker wires were touching.

your test audio file doesn't sound bad, i believe it's the microphone quality. mine has more treble yours sounds too much base on my speakers

i don't believe you can improve the noecho as this is how it sounds. it's really not an echo but noise canceling frequencies

We have a few options here to try. I'll give you what I think will most likely work first. In the terminal run xed admin:///etc/modprobe.d/alsa-base.conf and when the file opens, scroll to the bottom and add this one line:

Code: Select all

options snd-hda-intel model=alc269-dmic

Then save the file, reboot and test your mics.
