Monitoring Audio/Source devices on Windows

[Ilya Aleshkov]

Hi,

I'm investigating device monitor events for Audio/Source devices.
I'd like to receive appropriate events for built-in webcams microphones
(and for external microphones as well).

Please take a look at the "gst-device-monitor-1.0 -f" output. Every time I
used the same scenario - I removed and then added the same camera
(Microsoft LifeCam HD-3000) while another camera (Logitech C922 Pro Stream)
was plugged in.

Ubuntu 18.04 (GStreamer 1.14.5): - That's how it should work
Device removed:
    name  : Microsoft® LifeCam HD-3000: Mi
Device removed:
    name  : LifeCam HD-3000 Analog Mono
Device found:
    name  : Microsoft® LifeCam HD-3000: Mi
Device found:
    name  : LifeCam HD-3000 Analog Mono

Ubuntu 19.10 (Gstreamer 1.16.1): - It's not an ideal case but is still
usable
Device removed:
    name  : Microsoft® LifeCam HD-3000: Mi
Device modified:
    name  : C922 Pro Stream Webcam Analog Stereo
Device modified:
    name  : LifeCam HD-3000 Mono
Device found:
    name  : Microsoft® LifeCam HD-3000: Mi
Device modified:
    name  : C922 Pro Stream Webcam Analog Stereo
Device modified:
    name  : LifeCam HD-3000 Mono

Windows 10 (GStreamer 1.14.4/1.16.1/1.16.2): - Nothing about Audio/Source
devices at all. I still can workaround it but not for an external mic.
Unfortunately, I don't have one to test with it.
Device removed:
        name  : Microsoft LifeCam HD-3000
Device found:
        name  : Microsoft LifeCam HD-3000

Is it a known issue? How to deal with this situation?

Thanks,
Ilya
