Well yes, but I don't suppose keep trying and failing on things doesn't exist
is an efficient way, even if assume it's not bugged? Shouldn't there be faster
way to filter out what's on the "list" does not exist first?

But now it seems like PulseAudio even try to open hdmi logical devices on a
card even when the card does not have a single one itself, as per aplay -L

Will attach another log with timestamps with all my three cards enabled.
