+ *   Analog chip: AK4524 (partially via Philip's 74HCT125)
+ *   Digital receiver: CS8414-CS (not supported in this release)
+ *
+ *   Envy connects to AK4524
+ *	- CS directly from GPIO 10
+ *	- CCLK via 74HCT125's gate #4 from GPIO 4
+ *	- CDTI via 74HCT125's gate #2 from GPIO 5
+ *		CDTI may be completely blocked by 74HCT125's gate #1 controlled by GPIO 3
