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