Why not? The blocker problem seems to be that module-tunnel reports the
latency wrong, and I suggested a fix for that: avoid the
pa_sink_render() call in module-tunnel.c until the latency information
is available. pop_cb() in module-combine-sink.c is called by
pa_sink_render(), so if pa_sink_render() is called only when the latency
information is correct, then the latency information will always be
correct also in pop_cb().
