All cards (32, 32/8, 32Pro) are working identical 41 * in this mode. Rec data and play data are using the same buffer therefore. At 42 * first you have got the playing bits in the buffer and then (after playing 43 * them) they were overwitten by the captured sound of the CS8412/14. Both 44 * modes (play/record) are running harmonically hand in hand in the same buffer 45 * and you have only one start bit plus one interrupt bit to control this 46 * paired action. 47 * This is opposite to the latter rme96 where playing and capturing is totally 48 * separated and so their full duplex mode is supported by alsa (using two 49 * start bits and two interrupts for two different buffers). 50 * But due to the wrong sequence of playing and capturing ALSA shows no solved 51 * full duplex support for the rme32 at the moment. That's bad, but I'm not 52 * able to solve it. Are you motivated enough to solve this problem now? Your 53 * patch would be welcome! 54 * 55 * **************************************************************************** 56 * 57 * "The story after the long seeking" -- tiwai 58 * 59 * Ok, the situation regarding the full duplex is now improved a bit. 60 * In the fullduplex mode (given by the module parameter), the hardware buffer 61 * is split to halves for read and write directions at the DMA pointer. 62 * That is, the half above the current DMA pointer is used for write, and 63 * the half below is used for read. To mangle this strange behavior, an 64 * software intermediate buffer is introduced. This is, of course, not good 65 * from the viewpoint of the data transfer efficiency. However, this allows 66 * you to use arbitrary buffer sizes, instead of the fixed I/O buffer size. 67 * 68 * **************************************************************************** 69 */ 70 71 72#include <linux/delay.h> 73#include <linux/gfp.h> 74#include <linux/init.h> 75#include <linux/interrupt.h> 76#include <linux/pci.h> 77#include <linux/module.h> 78#include <linux/io.h> 79 80#include <sound/core.h> 81#include <sound/info.h> 82#include <sound/control.h> 83#include <sound/pcm.h> 84#include <sound/pcm_params.h> 85#include <sound/pcm-indirect.h> 86#include <sound/asoundef.h> 87#include <sound/initval.h> 88 89static int index[SNDRV_CARDS] = SNDRV_DEFAULT_IDX; /* Index 0-MAX */ 90static char *id[SNDRV_CARDS] = SNDRV_DEFAULT_STR; /* ID for this card */ 91static bool enable[SNDRV_CARDS] = SNDRV_DEFAULT_ENABLE_PNP; /* Enable this card */ 92static bool fullduplex[SNDRV_CARDS]; // = {[0 ...
