It’s time to sort out my confusion about the so-called “Audio Input” in devices widget, as I’ve been trying to pass my mic to my signal appvm for the past couple of hours, which left me with only even more confusion than before.
My device in dom0 widget is described as “dom0:mic - Microphone”, which I can attach to all of my running vms.
My mic is registered in dom0 volume control, as can be seen on the screenshot, and the bar reacts to my voice.
- Do I need to attach it to a vm like a block device, or is it supposed to work like audio output works (though vchan)?
- If you’re supposed to attach it, why is a mic present in my xfce pulseaudio plugin? Why is it out of sync with settings in volume control panel? Muting it in widget doesn’t mute it in volume control. What takes precedence?
- How is an appvm supposed to recognize this attached mic? As a vchan source or as something else? What command am I supposed to use in my appvm to see if it has recognized my mic?
- How secure is an action of attaching a mic to a vm?
