No sound from Jack (10.6)

[pc_junk@…]

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

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 ?

Another go with the command output wikified -

Is this reproducible with 0.118.0_1?

I am able to reproduce this issue using jackd 0.121.3 on OSX 10.6.8.

I've justed tested this with jack2 (#54870, [e36ae16764409c89e717408941b18dbf2719a233/macports-ports]) and it works for me. Since I can't test on 10.6 (and have little interest in fixing problems on such an old system) I'm going to assume this is no longer relevant or solved.
