Hi

I have install jack_capture and how can I run it?

$ jack_capture
./jack_capture
Cannot connect to server socket err = No such file or directory
Cannot connect to server request channel
jack server is not running or cannot be started
JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock
JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock
>>> jack_client_open() failed, status = 0x11


So I start jackd :

$ jackd -d coreaudio

then start jack_capture

$ jack_capture

then it starts to record, but the audio file I got jack_capture_01.wav is just blank

Anything wrong? 

Thanks

Yes, that's what jack_capture was made for. Just run it without any
arguments, and it will record a stereo file, floating point wav, to
disk.
