No Wav Trigger output at first power up after long down time.

Sensors Sound & Audio

I could successfully make my Wav Trigger play files from my 16GB SD Card.

If I remove 12V power and don’t plug it back in for any duration longer than 2mins, it won’t play audio from speakers (instead I hear longer electronic noise/beep from the board). After this, if I unplug and plug it back in, the audio works fine.
