GUVCView error - Sound not recording

[djg_s39c]

I can’t seem to record sound on any integrated (Using Linux Manjaro) Video/Audio recorder. I have tried using GUVCView from the command line and I get the following error:

I have been able to record sound with the sound recorder app.

I can record video with GUVCView, but no there is no sound recorded along with the video.

I see that ALSA and JACK errors are generating. A pull of the logs with inxi -Fxzc0 gives:

           Sound Server-1: ALSA v: k5.11.19-1-MANJARO running: yes 
           Sound Server-2: JACK v: 0.125.0 running: no 
           Sound Server-3: PulseAudio v: 14.2 running: yes 
           Sound Server-4: PipeWire v: 0.3.28 running: yes 

Not sure what to do next to get integrated sound recording with this application.

I have tried turning on Jack and then attempting to record with GUVCView. From the command line:

I can see the volume indicator moving when I make noise, showing that the recording device is recognised, but, clearly, there is no sampling going on:

I also have the same problem, though I start the software in graphical mode. The is no sound reproducing the recording, although I can see it being recorded.

I have tried VLC and Webcamoid with the same result. Which, in my humble opinion, makes me think the trouble is with the system. I use Cinnamon.

Under Windows in virtual machine, there is recorded sound.

Hello @jojopara , I have found a recording workaround by installing webcamoid directly, i.e not through the package manager but by installing it directly from here (using the ar image). It’s not a solution and I don’t know why it works installing directly, rather than through the package manager, but hopefully this helps. I’m not using Cinnamon so I can’t promise anything. Let me know if you find a solution.

[jojopara]

It is true that all three methods of installation that you, djg_s39c have given in the link work. However, I cannot understand how to use it as all three installations result in mirroring the desktop until this process stops. Good that Alt + F4 closes it.

[djg_s39c]

Hello @jojopara , indeed you can capture the desktop screen with webcamoid. In order to use it with your recording device, though, you must select that device in the ‘configure Sources’ section. Click this button to get there:
Once there, select your webcam. It should be in the list you will see in the top left of your screen (i.e don’t have Screen 0 selected. This is the output from your desktop and is why you are seeing what you are seeing):

Once you have done this, you should see output from your webcam. Let me know if you have any more difficulties.

Thank you for the reply. This is what I get:

Okay, that’s not a bug. That’s art.

But seriously, I’m not quite sure why you’re seeing that. I see that the application doesn’t even detect your webcam. Hopefully someone comes along with more knowledge than me on that one. Apologies, wish I had something more constructive for you. Stupid question; the webcam is plugged in and turned on?

[jojopara]

Thank you for the reply!

The webcam is plugged in and turned on. I have already gven hope to use guvcview or webcamoid. I shall revert to Debut Video Capture in my VM Windows.

After switching to kernel 5.15, I can now record hear recorded sound.
