 Hi,

 I have installed the Jack port and although this superficially appears to
 be running I can't get any audio output -

 ~ % jackd -d coreaudio -l
 jackd 0.116.2

 JACK compiled with POSIX SHM support.
 loading driver ..
 ICI
 Device name = 'Built-in Input', internal_name = 'AppleHDAEngineInput:1'
 (to be used as -d parameter)
 ICI
 Device name = 'Built-in Output', internal_name = 'AppleHDAEngineOutput:0'
 (to be used as -d parameter)

 ~ % jack_lsp -A
 system:playback_1
    coreaudio:Built-in Output:in1
 system:playback_2
    coreaudio:Built-in Output:in2

 % jack_metro -b 100
 (...no output)

 Any ideas ?
