[Media_api] PortMidi reports success on init but ALSA ouputs errormessage

[Roger Dannenberg]

Sebastien,

	Cpr is right -- it should not be an error to initialize PortMidi
even if there are no devices available. But did you get the console error
message after initialization or when you try to open a device? You may be
right that there's a problem.
	I'm definitely behind on putting out a new release with some mostly
minor fixes, but on the other hand, a lot of people seem to be using
PortMidi without complaints, so low activity levels is seen as a virtue. I
certainly want to track down and fix bugs as they are discovered, so let me
know.
