"I turned the sound back on and nothing comes out of the speakers", with
a log that reports success at every step: the network audio stream up,
664-byte packets arriving, the monitor started. The render goroutine's
error was thrown away — a device unplugged, renamed by Windows or unable
to open at 16 kHz fails exactly there, silently.
It is logged now, with the device id. Two once-only lines either side of
it say whether the decoded audio is reaching a running monitor or
arriving with nobody listening, which separates a device fault from the
speakers simply being switched off.
