Does your Phantom (Gold) have a hum/buzz?

If I press the button on the back of the Phantom for about 8 seconds, the woofers makes a sound and the annoying noise disappears on my Golds. Seems like it's a way to turn the speakers off. I thought the culprit was the PSU, but if the noise stops when pressing the button, the WiFi module is more likely to blame? The speakers are missing in Spark after the 8 seconds push procedure.
