My audio chain does not use a GR audio_sink of any description — it exits the flowgraph through a single message_sink after vectorizing the channels. The other two misbehaviors don't involve audio, or any sources or sinks. Furthermore, they can both be described as a subgraph (in one case, a concrete hier block) which has a single input and a single output, but two paths _within_ that subgraph which split and rejoin, and those two paths become out of sync with each other. -- Kevin Reid <http://switchb.org/kpreid/> _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
