    i am running Xubuntu 18.04.6 and Pulse Audio 11.1. it also has ffmpeg 3.4.8 and simplescreenrecorder 3.8. both of these record video but do not record any sound. both audio sources are tried in simplescreenrecorder. i'd prefer a command line way to do this so i want to focus on ffmpeg for now.

    since video is not an issue right now, i am posting this in "Off topic".

  2. The video section is for both video and audio....Moving you. But isn't this same as your other topic?

    i thought that since the site name is videohelp then audiohelp was off topic. my bad. so i should think of this site as media help.

    my earlier question was about recording video with audio. the video is working but the audio is not. in Linux, these come from different internal services. i have some understanding of the way it does video, but not about audio, so i considered it to be a separate issue so i could focus on and learn more about audio, especially with Pulse Audio.

    i guess no one knows a way to get audio (just audio) that is playing on Pulse Audio to be recorded to an audio file.

  5. HI Mate, heres how to record pulseaudio using sox

    install sox

    Code:
    sudo apt install sox
    record-desktop-audio shell script

    https://raw.githubusercontent.com/NapoleonWils0n/ubuntu-bin/master/record-desktop-audio

    download the script with curl

    Code:
    curl 'https://raw.githubusercontent.com/NapoleonWils0n/ubuntu-bin/master/record-desktop-audio' -o ~/Desktop/record-desktop-audio
    move the script to /usr/local/bin

    Code:
    sudo mv ~/Desktop/record-desktop-audio /usr/local/bin
    if you have a ~/bin directory in your home you can also move the script there

    Code:
    mv ~/Desktop/record-desktop-audio ~/bin
    run the script with the -h option to display the help

    Code:
    record-desktop-audio -h
    run the script and specify an output file with the -o option

    Code:
    record-desktop-audio -o pulseaudio.wav
