16 * - use the DSX channels for the first pcm playback.
17 * (on VIA8233, 8233C and 8235 only)
18 * this will allow you play simultaneously up to 4 streams.
19 * multi-channel playback is assigned to the second device
21 * - support the secondary capture (on VIA8233/C,8235)
23 * the DSX3 channel can be used for SPDIF output.
24 * on VIA8233A, this channel is assigned to the second pcm
26 * the card config of alsa-lib will assign the correct
27 * device for applications.
28 * - clean up the code, separate low-level initialization
29 * routines for each chipset.
31 * Sep. 26, 2005 Karsten Wiese <annabellesgarden@yahoo.de>
32 * - Optimize position calculation for the 823x chips.
