NOFAIL means we don't fail if the daemon is not available when
pa_context_connect() is called and instead enter PA_CONTEXT_CONNECTING
state and wait for the daemon to appear.
So currently if pulseaudio isn't running or available, ponymix will just
block and wait. Since a lot of people use ponymix bound to their volume
keys, this could potentially mean spawning 100s of processes before
actually catching on that things aren't working.
PA_CONTEXT_NOFLAGS was introduced in 0.9.19. Its really just 0.

Add a Notifier virtual base class and a CommandLineNotifier
implementation which handles output of volume and balance levels after a
change.

Avoid invoking the copy constructors and storing new objects which can't
be returned (as they're local variables).

Unless explicitly specified, target a card based on the selected device.
Note that not all devices will be tied to a card.
falconindy » put differently, if i have multiple cards, what determines which
card is used by pulse for a given app?
tanuk » In theory, the logic can be anything (it depends on what
policy-implementing modules are loaded). By default, routing is mostly
handled by module-stream-restore, which chooses the sink based on the
user's previous routing choices.
tanuk » If the user hasn't done any routing choices, the fallback logic is to
select the current "default sink".
tanuk » I don't recommend trying to guess the routing policy.
falconindy » i guess my understanding of pulse internals is lacking
falconindy » but that's rather enlightening
falconindy » is there any way to figure out the connection between a sink and a card?
tanuk » Yes... (One moment, I'll look up things.)
falconindy » ah. uint32_t card
falconindy » appears to be in pa_sink_info
falconindy » so that ties the sink to the index of a card?
tanuk » Yep.
falconindy » awesome, that's good enough for what i need to do
tanuk » Not all sinks are part of a card, though, but those that are will have
the card index set.
falconindy » also good to know

A few changes make this fun and easy:
- Merge the function array into the string to action lookup and return a
Command instead of simply an enum. A Command is the function and the
min/max arg count.
- Implement an InRange method for the Range class.
- Add a Dispatch function to convert the string to Command and validate
the arguments.
This leaves us in a position where the argc parameter to each method is
never used, but maybe some day a command will be added that takes a
range of args rather than a fixed number.
