How to capture audio from speaker in Bionic64?

[arivas_2005]

Cheers
I have puppy bionic 64 installed and I can't capture the sound coming out of the speaker
i have installed mhwave, audacity, pavrecord, baconrecorder, precord
neither one can capture the audio.
I have only managed to capture the audio from the microphone with the line
arecord -vv -fdat /foo.wav
but with enough noise
I wish you could guide me step by step to capture the entire desktop plus all the sound from the pc (internal and microphone)

I perform the tests by running a youtube video in opera browser (and the sound is good)

Try changing the "Loopback Mixing" in Retrovol from disabled to enabled.

Yes, was just going to say that too, to add: enable also "Capture" (and adjust volume of course).

Thanks
I have already made the suggested changes and in the apps if you see the sound monitoring bars that fluctuate, but in the file that is created there is only deafening noise (minimal noise) .. and nothing of the sounds

have a good year 2021
I come again requesting support to solve my difficulty with saving the audio
The problem is that only the audio from the microphone can be stored and I can't find a way to capture the audio from the applications
trying options I installed mageia 5 32 bits and the problem was different (opposite) .. here only the audio from the apps is saved and the microphone is not saved
I have searched with google and I summarize that it is difficult to handle the commands for the configuration of the sound card.
I use Puppy BIonic 64 bits, and the apps mentioned above only capture when the sound is from the microphone. (audacity, mhwavedit, pavrecord, .. acrecord,)
in the case of ffmpeg I cannot capture sounds neither from the app nor from the microphone.
If you could suggest some other forum in which I can request help to overcome this difficulty
I attach the report of alsa sound wizard report
thanks

I have a mic/headphone shared socket & so I got a cheap usb sound card with separate mic & headphone & connected a cable between those.
Now record clear sound.

I used to rip audio from youtube with vlc. Its been so long ago, I would have to google how again.

@ozsouth :-

Oz, d'you mean to tell me that actually works? Surely, connecting the headphone output direct to the mic input, well.....wouldn't you get horrible feedback issues? And through the same USB port, too?

If this works, I might have a go with this myself. This new HP Pavilion tower has to be the only one I've come across where the Realtek chip simply doesn't recognise 'loopback mixing' at all. I have absolutely everything - including the kitchen sink, and several options I've never even heard of before! - showing up in Retrovol/Alsamixer, but the one I want - loopback mixing - just isn't there.

I've got one of these USB sound cards (a 'Plugable'); had it for a while, in fact. AND I've got several audio cables, in all different lengths.....with 3.5 mm jack plugs.

Hmm. I sense an experiment coming on, y'know.....?

Mike.

@mikewalsh - works for me on my laptops, whereas loopback doesn't. I guess if audio levels are very high one might have issues. In my dim dark distant desktop days - when sound cards had separate input & output sockets, I connected them with a cable too. You can use this method to grab youtube videos with FFconvert that many puppies have (or ffmpeg on command line).

Well, I'll give it a try tomorrow; see what happens, like. It's got two chances....!!

It astonishes me, actually. Reading up on the Archlinux wiki earlier on, Intel sound cards - like I have here, sorry; NOT Realtek - if 'stereo mix' isn't present, 'dmix' automatically kicks-in for playback.....but there's no such provision for the recording side of things. Buggers..!

I'll try it, anyroad. I'll let you know what the outcome is. I can grab Youtube vids with Fred's YouTube-dlc thingy (summat like that, anyroad!), and audio is fine. But if I want to record audio on its own, or have background music playing softly while I do a tutorial, say, I can't grab it via screen-recording at the time; I have to add it as a separate track during editing/rendering. Which is.....annoying.

Catch ya later.

Mike.

You could try How to capture audio output.

Not sure if this works for the op since there is a loopback mixer in retrovol, but for those who do not have a loopback mixer on intel sound cards it may help... I used it several times on my laptop.
