Lab 3: Audio

To workaround this two clock problem, set the Audio Sink to non-blocking mode (not 'OK to Block') so that it will never hold up the flowgraph (i.e. not apply backpressure). It will consume samples as normal, but if there is ever an excess (e.g. the USRP is producing samples a little faster than the Audio Sink can consume) it will drop the samples (might cause audio glitches).
This does not solve the case where samples are being produced slower than the Audio Sink's consumption rate (this will produce an underrun: audio will sound choppy and 'aU' will be printed).
