25 * Audio controller: VIA Envy24HT-S (slightly trimmed down version of Envy24HT)

27 * Digital receiver: CS8414-CS (not supported in this release)
28 *
29 * Envy connects to AK4524
30 * - CS directly from GPIO 10
31 * - CCLK via 74HCT125's gate #4 from GPIO 4
32 * - CDTI via 74HCT125's gate #2 from GPIO 5
33 * CDTI may be completely blocked by 74HCT125's gate #1 controlled by GPIO 3
