I believe I’ve figured it out. I just noticed this error message from jackd:

Failed to connect to session bus for device reservation Unable to autolaunch a dbus-daemon without a $DISPLAY for X11

I’ve been trying to use jackd from the console without ever starting X. So, for a lark, I tried starting X inside my vncserver, and lo and behold jackd started with mplayer.

Following the build instructions more closely on

http://supercollider.github.io/development/building-raspberrypi.html

I built jack2 1.9.10 (from git) and this X dependency is no longer an issue. I can start jackd like this in the console:

jackd -P70 -p16 -t2000 -dalsa -dhw:0,0 -n3 -r44100 -s -S -P

And then play a stream through it with mplayer:

mplayer -ao jack test.m4a

Works great, no glitches. No X windows is a good thing.

Now, I completed a build using distcc over night, and I then did

sudo make install

If I try to run scsynth, I get the following:

[pinecraft:~] scsynth -u 57110

JackDriver: client name is 'SuperCollider'

SC_AudioDriver: sample rate = 44100.000000, driver's block size = 1024

zsh: segmentation fault  scsynth -u 57110

If I try to run sclang, I get this error message:

For advice: [http://supercollider.sf.net/wiki/index.php/ERROR:_server_failed_to_start]

I assume scsynth crashing on its own is the culprit. I’m starting a local build with swap now to see if raspian’s gcc-4.7.2 gives any better results.
