Received Defective SparkFun Sound Detector - What are RMA options?

Sensors Sound & Audio
1

I received my SparkFun Sound Detector yesterday and properly connected it to +5V regulated power supply.

No voice signal on the Audio pin as measured with oscilloscope.

Started to chase out voltages across the board and noticed that the LMV324M amplifier device was ROASTING hot.

Verified once again that VCC and GND are properly connected and that 5V is applied to the device.

This device is defective. How do I return it for functional one?
