Record audio with SimpleScreenRecorder? [ SOLVED ]

[Amaponian]

Why I can't record audio with SimpleScreenRecorder ?
Has someone done this with PuppyLinux?

Greetings !

What version of Puppy?

Hi Amaponian,

This solution by Pelo helped me: http://www.murga-linux.com/puppy/viewtopic.php?p=905246#905246

I solved the problem following the steps described in this post:

Thanks to disciple who provided the link.
Also thanks to Sailor Enceladus (previous post) who led me to the post where I found the final help.

This worked for my Distro: tahrpup64 6.0.5

Three steps:

1. Append to the file /etc/asound.conf this code:

Code: Select all

pcm.!default { 
  type asym 
  playback.pcm "LoopAndReal" 
  #capture.pcm "looprec" 
  capture.pcm "hw:0,0" 
} 

pcm.looprec { 
    type hw 
    card "Loopback" 
    device 1 
    subdevice 0 
} 


pcm.LoopAndReal { 
  type plug 
  slave.pcm mdev 
  route_policy "duplicate" 
} 


pcm.mdev { 
  type multi 
  slaves.a.pcm pcm.MixReale 
  slaves.a.channels 2 
  slaves.b.pcm pcm.MixLoopback 
  slaves.b.channels 2 
  bindings.0.slave a 
  bindings.0.channel 0 
  bindings.1.slave a 
  bindings.1.channel 1 
  bindings.2.slave b 
  bindings.2.channel 0 
  bindings.3.slave b 
  bindings.3.channel 1 
} 


pcm.MixReale { 
  type dmix 
  ipc_key 1024 
  ipc_perm 0666 
  slave { 
    pcm "hw:0,0" 
    rate 48000 
    #rate 44100 
    periods 128 
    period_time 0 
    period_size 1024 # must be power of 2 
    buffer_size 8192 
  } 
} 

pcm.MixLoopback { 
  type dmix 
  ipc_key 1025 
  ipc_perm 0666 
  slave { 
    pcm "hw:Loopback,0,0" 
    rate 48000 
    #rate 44100 
    periods 128 
    period_time 0 
    period_size 1024 # must be power of 2 
    buffer_size 8192 
  } 
} 

2. Execute in terminal/console this command: modprobe snd-aloop (you'll probably want to add this to your Startup)
3. Set the Audio Input in SimpleScreenRecorder as specified in the following lines, then complete your recording with SimpleScreenRecorder.
For recording audio using another app see the link provided at the beginning of this post.

This should be a PET so that PUP distro developers can include in future distros. OR, it should be a feature in PUP distros.

Anyone know if this is included in any PUP distros?

Hi,
tons of thanks to Amaponian !

I solved the problem following the steps described in this post:
http://www.murga-linux.com/puppy/viewtopic.php?t=95431
...
Three steps:
1.
2.
3.

Here -on Dpup Stretch 7.5 RC4- needed to add a step:
between step 1. and step 2. in Amaponian's post

1.1 Reboot computer

in order ALSA to apply the new asound.conf

To test if the "sound recording" is working, one might press the "Display Preview" (see herunder shot) button in the last SSRs dialog box: there the preview window has 2 vu-meter scales.
Sound recording is working if those scales are green/yellow/orange coloured, and moving according to sound intensity (provided the video to be recorded is playing! - if not, they keep grey coloured).

To mention:
if one might unload the snd_aloop module, type in terminal

Code: Select all

# modprobe -r snd_aloop

HTH

@ charlie6:-

I have to admit, I found a much simpler solution.....completely by accident!

Around a year ago, I was shopping around for a USB 'headset' - combined headphones with a 'boom' microphone, which I wanted for doing screencasts. As it turned out, the Logitech model I purchased (an H340) has its own, built-in soundcard in the rather chunky USB connector.

To my complete astonishment, once I'd set the headset as the default soundcard, not only did audio recording work perfectly in SimpleScreenRecorder.....it also worked A-OK in RecordMyDesktop, XVidcap, and wiak's WeX screencaster, too!

The only caveat? Just make sure that whatever the headset's card is - in my case, 'hw:2' - is selected in every app's preferences. Some like it named specifically; others simply need it to be set as the default.

Seemingly, all the awkward 'workarounds' folk have always needed to employ in Puppy over the years for audio recording are smoothly taken care of by the chipset this thing's soundcard uses. I can't recommend it enough.

Even under Linux, this thing just 'works'.....in large part, I would guess, due to having that built-in soundcard (which cuts down on all the 'hoops' your system's built-in card otherwise needs to jump through in order to get a connection established).

https://www.logitech.com/en-gb/product/usb-headset-h340





Notice the relative size of that USB connector. That's where the sound-card lives.

The boom microphone is a short, stubby type.....with digital noise-cancelling built in. (Works well, too; it really cuts down on stray, background noises.)

And changing the default soundcard is a breeze in the newer Pups, with the modern version of the ALSA Wizard's GUI. Easy-peasy....
