OK, I have Hydrogen among the CCRMA applications.

I've tried it both ways but will start jackd with QJackctl first for
consistency.

Yes, I have an Intel HDA as reported by amixer:
[rfox at kolea ~]$ amixer -c0 info
Card hw:0 'Intel'/'HDA Intel at 0xefffc000 irq 21'
Mixer name : 'SigmaTel STAC9200'
Components : 'HDA:83847690 HDA:14f12bfa'
Controls : 13
Simple ctrls : 6
OK, have done this. Periods/Buffer is now 3 (was 2) and Interface
points to "hw:0". No change to Frames/Period just yet.

Assume you mean the "Start" button...

started hydrogen from the command line:

There's already a pair of connections under the Audio tab of the
Connections dialog:
Hydrogen-1 system
out_L -------------------- playback_1
out_R -------------------- playback_2
(Hydrogen File->Preferences->Audio System has a checkbox for "Connect to
default output pair" that seems to be doing this - I can't uncheck this
box)

Nope.
The Hydrogen status line changes to "Playing." for 5 seconds, then
changes back to an empty status line.
The timecode meter never changes from 00:00:00
No sound at all.

Can't check while Hydrogen and Qjackctl are hooked up as I get the
following output:
[rfox at kolea ~]$ speaker-test -c2 -twav
speaker-test 1.0.16
Playback device is default
Stream parameters are 48000Hz, S16_LE, 2 channels
WAV file(s)
ALSA lib pcm_dmix.c:996:(snd_pcm_dmix_open) unable to open slave
Playback open error: -16,Device or resource busy
but after stopping jackd with QJackctl
[rfox at kolea ~]$ speaker-test -c2 -twav
speaker-test 1.0.16
Playback device is default
Stream parameters are 48000Hz, S16_LE, 2 channels
WAV file(s)
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 2048 to 8192
Period size range from 1024 to 1024
Using max buffer size 8192
Periods = 4
was set period_size = 1024
was set buffer_size = 8192
0 - Front Left
1 - Front Right
Time per period = 2.856941
0 - Front Left
1 - Front Right
Time per period = 3.008038
0 - Front Left
1 - Front Right
The volume on both speakers is fine.
This is driving me crazy but I don't know where to look for the problem.
Again, the output from alsa-info is posted at http://pastebin.ca/1069099
and I'd be happy to post output from other commands or post
configuration file contents.
