Ok, nobody answered, perhaps my question was too stupid :)) I still haven't found in the docs how can I get from ALSA the address of the blocks to play/record, or how to tell ALSA where it the space I allocated so it knows where it has to write the audio data to be played. I can build a very generic scatter-gather list. It has three instructions: addr/length, generate interrupt, jump. Per example I can write an sg list like this to emulate the cyclic buffer of many soundblaster cards: start: addr0/len0 Irq addr1/len1 Irq goto start Bye. ------------------------------------------------------- This SF.net email is sponsored by:Crypto Challenge is now open!
