Always press START only once. Be like
a pilgrim and have patience - wait until
you hear the audio start.
Long audio latency may occur if your
connection with the internet is weak.
Pressing START more than once,
might multiply the audio out.
If this happens, press STOP until all
audio ends.
Then press START again - only once!
