Re: [Discuss-gnuradio] Question about ZeroMQ Sub source

[Vanush Vaswani]

I tried it but it's still very choppy.

I'm not 100% on the scheduler, but if the downstream graph requests 4096 items, and the zmq message size is 8192 items, wouldn't this result in choppy audio?

Regards,

With pub/sub, the subscribers must keep up--a pub sinks have fire and
forget semantics.

Your are better off with push/pull here, the downstream flowgraph will
pull as needed and the upstream push block will wait.
