OK, so now you have set your "normal" sound card to Off. Is this intended?

Normally I'd expect you to want to keep both cards available but only
use the one you want at any given time.

Anyway, Firefox is able to output sound, but is that sound going to your
normal sound card or to your HDMI?

If your normal sound card then firefox is bypassing PA and accessing the
h/w directly. THis can cause other apps to not be able to ouput.

In your listing, I do not see any "Sink Input" (i.e. playback streams),
so that suggests no app is actually playing audio via PA at the time you
grabbed it. I would suggest that something is not configured correctly
at that level (e.g. are you apps using alsa output and is alsa not
configured correctly to use the PA plugin? If possible configure the
apps to use PA directly rather than going via the alsa plugin)
