fix: a playback that never starts no longer fails silently

From an operator's log, playing a recording on the air repeatedly:

  18:52:40.148 play → 18:52:48.420 PTT released   8.2 s, the whole take
  18:52:57.759 play → 18:52:57.879 PTT released   0.12 s, nothing came out

Those 120 ms are the PTT release tail alone: the render device refused to start
and playPCM returned an error that was thrown away. The call reported success
every time, which is what "it plays once and then never again" looks like from
the outside — and why the search went to the recorder, which was innocent.

The error is now logged with the device name.
