Hi
What do you mean `jack playing something?`
I just played some youtube video on Chrome.
What else should I do?
Thanks

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
Is jack playing anything? (jack_capture only records audio played by jack)
>> 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?
