My app can handle that now, but the way how I had to do it defeats the 'zero-copy' paradigm. The situation is this: the application requests a 16kb buffer, at 2 channels / U16LE this makes a 4096 frames. It's a streaming buffer and the app writes in the data in chunks of 4096 bytes. I can't map the alsa mmap'ed buffer to the application (because of the different size) so I have to create my own temporary buffer and then copy the data to the mmap'ed buffer. tom ------------------------------------------------------------------------- Take Surveys.
