Bug description:
[Impact]
Bogus HDMI audio can be selected as output, without any HDMI monitor
connected.
[Fix]
Consider 0 SAD as invalid ELD - no SAD means no audio.
[Test]
With the patch applied, no bogus HDMI audio can be found in GNOME's
setting app.
[Where problems could occur]
Basically none. No SAD means no PCM - so it has never worked before.
