[SOLVED] Audio Recorded Via Webcam Microphone Sounds Gibberish

blueray · 06-27-2020, 10:52 AM

My webcam video recording is working.

When I am making sound, my webcam microphone is receiving sound.

However, when I playback the sound, it is nothing but noise.

It sounds like this

My current system is

Code:

    $ inxi -F

I was trying to record audio using audacity and cheese.

Then, I tried to record sound using arecord and this is what I get:

Code:

    $ arecord --list-devices

    $ arecord -f dat -r 60000 -D hw:1,0 -d 5 test.wav
    Recording WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 60000 Hz, Stereo
    arecord: set_params:1305: Channels count non available

What does set_params:1305: Channels count non available mean and what is the solution of this noise here?

I have tried Static noise in microphone recording and Microphone distorted due to automatic adjustment

I have just updated my kernel

Code:

$ uname -r
5.4.0-39-generic

It is still not working.

No solution, but some ideas for further testing:

Do you have the correct sound input source selected in Audacity?

Have you tested with a known-good microphone plugged into the mic jack to verify that the jack itself is functional?

You don't mention which distro you are using for this, but, if it uses Pulse Audio, install the Pulse Audio Mixer (pavucontrol--it should be in the repos), then check the settings for that input device.

I gave up on that hardware. Looking for a new webcam.

I discussed about this issue in Linux Mint forum.

I came across something that fixed my usb mic on this YouTube video https://www.youtube.com/watch?v=DrkZIT7w7Hc
The entire video is very useful, but for your issue the needed information starts 10 minute into it.
