CoreAudio driver input doesn't work

[jdek]

It works fine (doesn't crash) without asking for input:

user@computer ~/W/o/jack1> jackd -d coreaudio                                                                                                                                                       [master]

However, it doesn't find any input.

When explicitly asking for input, it just fails.

It exits immediately after failure.

I'm also seeing this, plus:

could not handle external client request

on any call that is made to jackd. This is the case for both pre- and post-#42.

@Qix- that's a separate issue afaict.
