27 | * Changes: | |
28 | * | |
29 | * Dec. 19, 2002 Takashi Iwai <tiwai@suse.de> | |
30 | * - use the DSX channels for the first pcm playback. | |
31 | * (on VIA8233, 8233C and 8235 only) | |
32 | * this will allow you play simultaneously up to 4 streams. | |
33 | * multi-channel playback is assigned to the second device | |
34 | * on these chips. | |
35 | * - support the secondary capture (on VIA8233/C,8235) | |
36 | * - SPDIF support | |
37 | * the DSX3 channel can be used for SPDIF output. | |
38 | * on VIA8233A, this channel is assigned to the second pcm | |
39 | * playback. | |
40 | * the card config of alsa-lib will assign the correct | |
41 | * device for applications. | |
42 | * - clean up the code, separate low-level initialization | |
43 | * routines for each chipset. | |
44 | * | |
45 | * Sep. 26, 2005 Karsten Wiese <annabellesgarden@yahoo.de> | |
46 | * - Optimize position calculation for the 823x chips. | |
