I want to record the sound from my MIC and the sound of a Youtube video but I can’t find the way to do that. Using pavucontrol I can choose record from MIC OR Monitor Of Internal Audio but don’t both. Is there a way to do that? I was able to record all the audio with the same hardware using Windows.


Not easily.

Three options:

  1. You could create a “virtual ALSA device” that mixes the inputs that you want to record, then record from the virtual device.

  2. You could install Jack audio system and QjackCtl, then use the “Connections” tool in QjackCtl to connect the required sound sources to Audacity.
    To set the connections, start Audacity recording, then Pause. While paused, Audacity will appear in the “Connections” screen as “portaudio”.

  3. Combine the audio streams using PulseAudio. (This topic may help:,119695.msg905379.html#msg905379)
