* Note #1 "Sek'd models" ................................... martin 2002-12-07
|
|
*
|
|
* Identical soundcards by Sek'd were labeled:
|
|
* RME Digi 32 = Sek'd Prodif 32
|
|
* RME Digi 32 Pro = Sek'd Prodif 96
|
|
* RME Digi 32/8 = Sek'd Prodif Gold
|
|
*
|
|
* ****************************************************************************
|
|
*
|
|
* Note #2 "full duplex mode" ............................... martin 2002-12-07
|
|
*
|
|
* Full duplex doesn't work. 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.
