1. Kill off pulse.

2. In terminal 1 start jack with

    bob$ jackd -d alsa -d hw:0,1

3. In terminal 2 start the metronome:

 bob$ jack_metro -b 60
Cannot read socket fd = 5 err = Success
JackSocketClientChannel read fail
Cannot open metro client
JACK server not running?

About 20 seconds later the metronome exits and jack exits as well:

bob$ jackd -d alsa -d hw:0,1

However, if I use hw:0,0 I can connect the metronome using qjackctl.
In this case it play though the regular audio port, not the digital.

Is this progress?
