Librem 13v4
Debian Bullseye Gnome 3.38.4
External sound card PnP
When I use software that can capture audio:
like Jitsi meet (on Firefox 86) or SimpleScreenRecorder
The Audio input Source list for the above two softwares has a number of options:
Monitor of Built-in Audio Analog Stereo
Built in Audio Analog Stereo
USB PnP Audio Device Mono
Monitor of USB PnP Audio Device Mono
My question is about the two Monitor devices -
What created these Monitor Devices
What for??
Thank you
A monitor as related to audio is a channel that allows you to listen to what is being recorded as it is being recorded. This allows you to adjust levels or restart recording immediately upon hearing an issue. Without that monitor channel, you would record the audio then play it back to hear if the recording level was where you wanted it and potentialy do several iterations of that.
The monitors you are seeing were most likely created by the PulseAudio server when the output capable audio device was plugged in.
