Package: orca
Version: 3.30.1-1
Severity: normal

Dear Maintainer,
I was trying to triage another bug by using orca
inside a minimal Buster amd64 qemu VM.

On that minimal system I installed just:
    apt install systemd-coredump xserver-xorg sddm plasma-desktop orca

When I tried to start orca in that system I received
this error:

    benutzer at debian:~$ GST_DEBUG=2 orca
    0:00:00.040783971  1024      0x1c45120 WARN     GST_ELEMENT_FACTORY gstelementfactory.c:456:gst_element_factory_make: no such element factory "autoaudiosink"!
    Traceback (most recent call last):

    File "/usr/lib/python3/dist-packages/orca/sound.py", line 123, in init
        self._pipeline.add(self._sink)
    File "/usr/lib/python3/dist-packages/gi/overrides/Gst.py", line 64, in add
        if not Gst.Bin.add(self, arg):
    TypeError: Argument 1 does not allow None as a value


sound.py:123
        self._sink = Gst.ElementFactory.make('autoaudiosink', 'output')


Unfortunately this "autoaudiosink" seems to be contained in
libgstautodetect.so which is included in package gstreamer1.0-plugins-good.

After installing gstreamer1.0-plugins-good orca could
be started and also gives audio output.

Would this qualify for a change to orca to suggest
or depend on package gstreamer1.0-plugins-good?

Kind regards,
Bernhard
