--- Comment #57 from Arun Raghavan <a...@accosted.net> ---
My primary concern with this patch series is that it is very common to plug in
multiple HDMI devices to a single laptop (monitors, projectors, ...), and it
appears that a preference to route to a single device ends up applying to all
devices.
David had mentioned that this *may* be a problem. I'd go as far as to say that
this is definitely a problem.
So as I understand it, we were looking at solving two problems:
1. Non-existent speakers when there is a speaker control
2. DPMS causing an HDMI unplug
For the first, I concur with David about this not being an issue we should try
to solve, and we should let underlying layers fix this properly. *Maybe* we
could look at having a pavucontrol option to mark a system as not having
internal speakers (and store this on the card in some way).
For the second, I don't have a good solution. Yes, it would be a _lot_ better
to be able to distinguish between the DPMS and unplugged states. There seemed
to be a suggestion that this is possible at the graphics driver level. Is that
true?
As an alternative, it may make sense to at least tie the preferred port setting
with the corresponding device names from ELDs. That would prevent us from
explicitly having to route to and away from every HDMI device explicitly. It's
still not great since ELDs lie, and it's common to have multiple monitors of
the same type being connected to (e.g. an office with homogenous monitor
setups, but you only have headphones connected to your own workstation).
