2 * ALSA driver for ICEnsemble VT1724 (Envy24HT)
4 * Lowlevel functions for AudioTrak Prodigy 192 cards
5 * Supported IEC958 input from optional MI/ODI/O add-on card.
10 * * SPDIF-OUT on the card:
11 * - coax (through isolation transformer)/toslink supplied by
12 * 74HC04 gates - 3 in parallel
13 * - output switched between on-board CD drive dig-out connector
14 * and ice1724 SPDTX pin, using 74HC02 NOR gates, controlled
15 * by GPIO20 (0 = CD dig-out, 1 = SPDTX)
16 * * SPDTX goes straight to MI/ODI/O card's SPDIF-OUT coax
18 * * MI/ODI/O card: AK4114 based, used for iec958 input only
19 * - toslink input -> RX0
