The row still asked for a capture through the PulseAudio null sink as the thing that settles it. Both routes are now closed: take 1 was corrupted by a channel-map remap, take 2 is starved by construction, and the monitor sink cannot be fixed by configuration -- it advances at wall-clock rate and substitutes silence. The route that works needs a Canary rebuild costed at a whole session, which is the human's call. Also records the withdrawal of the WMA-track concern: a starved file neither supports nor refutes it.
