Linux JACK support

[defensem3ch]

Seems that starting this on Linux defaults to PulseAudio. Is there a way for the emulator to output to JACK instead?

probably you can use SDL_AUDIODRIVER env var to select specific audio backend

I tried this, but didn't have success - audio device still selects "JACK sink (PulseAudio JACK Sink)" rather than jack

I tried it using export SDL_AUDIODRIVER=jack and got FATAL ERROR: Failed to initialize the SDL2: Audio target 'jack' not available.

You also need a SDL2 compiled with jack support.
Detection is automatic in the ./configure

I do have, but ran into:
FATAL ERROR: Failed to open the audio stream.

Strace give some:
