audio source using JACK
The source has one input stream of floats.
Output samples will be in the range [-1,1].

bool audio_jack_source::check_topology | ( | int | ninputs, |

Confirm that ninputs and noutputs is an acceptable combination.
ninputs | number of input streams connected |
noutputs | number of output streams connected |
This function is called by the runtime system whenever the topology changes. Most classes do not need to override this. This check is in addition to the constraints specified by the input and output gr_io_signatures.
Reimplemented from gr_basic_block.
