13 | * Changes: | |
14 | * | |
15 | * Dec. 19, 2002 Takashi Iwai <tiwai@suse.de> | |
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 | |
20 | * on these chips. | |
21 | * - support the secondary capture (on VIA8233/C,8235) | |
22 | * - SPDIF support | |
23 | * the DSX3 channel can be used for SPDIF output. | |
24 | * on VIA8233A, this channel is assigned to the second pcm | |
25 | * playback. | |
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. | |
