Reported: the recording plays once and never again, "as if it threw the sound
away after playing it". PeekQSO is what the playback reads and it is meant to
copy — TakeQSO is the one that clears — so this pins that, and that the copy is
independent of the recorder's own buffer.
It passes, which is the useful part: the take survives, so the one-shot failure
is downstream of it and the search moves to the file and the player.
