Audio input is too too sensitive that it causes echoing. It hears the slightest sound. Even sounds coming from my earphones, causing a really loud and annoying echo when I speak. I can turn the audio input down and it removes the echoing but now nobody can hear me. How do I fix this? There isn’t even a microphone audio test feature.

Start Audacity, and you can use it to record your microphone.

Give more detail how you test things because you didn’t give any.

I have KDE installed and the microphone input sensitivity can be adjusted with the loudspeaker icon.

I already tested it on Audacity and like I said, there’s no built-in test. It happens to every instance of audio input, no matter the program.

Echo/Noise Cancellation

The procedure(s) you need to follow to achieve the intended result will depend on whether you are using PipeWire or PulseAudio.

  • Pipewire: See Echo Cancellation in the PipeWire/Examples Arch/Wiki page.

  • PulseAudio: See 6.4 Microphone echo/noise cancellation in the PulseAudio ArchWiki page.

If you need a video; here’s one I found with a 5 second Internet search:

Cheers.

How do you control your Micro Volume? Maybe take a look in Alsamixer and do it from there?

Audio CoProcessor device is not loading a driver

AMD ACP/ACP3X/ACP6x Audio Coprocessor vendor: Lenovo driver: N/A

AMD ACP device should support the internal digital dual microphone array
But online scans show this device is not working on a number of other systems
https://linux-hardware.org/?id=pci:1022-15e2-17aa-381c

System probably needs a kernel patch to load acp3x or acp6x driver, similar to this discussion
AMD ACP/ACP3X/ACP6x Audio Coprocessor driver not detected

But even if the internal microphones were working correctly they would probably still need echo-cancellation software. Internal microphones on modern laptops are omnidirectional and capture all audio from any direction, including reverberation from walls and fan noise. A unidirectional (cardioid or super-cardioid) external microphone would help reduce or eliminate echo and background noise for VOIP calls

Open-back headphones that leak sound are also not good for VOIP calls
Better to use closed-back headphones or earbuds

Audio level meters in DE audio controls and panel widgets might not show microphone audio capture level accurately. Level meters in Audacity, (and other recording software) have much better level meters and analysis tools

There are also CLI tools to make test recordings of microphone audio
paracord for PulseAudio
pw-record for PipeWire
arecord for ALSA
