I've commented elsewhere on the thread, but, this also has the potential to be destroyed by software. That AUDIO_PWR_EN appears to be a signal that can be controlled by software. If you switch it fast enough such that the MOSFET is kept mostly in the linear region (due to the RC on the gate), you can kill the MOSFET very quickly.
