Ubuntu – Why does “Monitor of Built-in Analog Audio” Has no Sound

alsamicrophonepulseaudiosound

I started with Linux for about 4 or 5 months, moved from Mint 15 to Ubuntu 12.04 and I'm loving it all. Still getting used to terminal commands and the variety of software I can find here.

I currently have a Let's Play Channel on Youtube, so, I need to record gameplay footage (video and audio) along with microphone audio (in a separate file, with audacity).

I found a software called Simple Screen Recorder (SSR) to record gameplay video and audio footage, I have checked the website for instructions on how to adjust the things and the problems began.

First, the video is recorded just fine, it's the simplest software I could find to set up the configurations and get it up and running. Problem is, no gameplay audio, no system audio. Audacity records the microphone just well, so I started to take a look on the configurations on PulseAudio Volume Control while recording something with SSR. Many tutorials tell to change the audio imput to Monitor of Built-in Analog Audio in order to record the gameplay audio, but this did not work to me here.

I suspect that this Monitor of Built-in Analog Audio is not configured or that it does not have audio to be recorded at all, how can I fix this?

Thanks you for your attention!

I don't know how far you got in this process, so I start from the beginning:

  1. Install pavucontrol:

    sudo apt-get install pavucontrol
    
  2. Launch it:

    pavucontrol
    
  3. On the Input Devices tab select Show: All input devices
  4. Check the Volume level and if necessary Unmute the Monitor of Built-in Analog Audio channel by clicking on the little speaker icon.
  5. Launch Audacity, start recording
  6. While Audacity is recording: In the pavucontrol Recording tab change the Input Source for Audacity to Monitor of Built-in Analog Audio

Did that help?
