I am hindered in this chiefly by lack of documentation. If someone could supply me with the URL of some documentation on kernel sound handling it would be much appreciated. I am also somewhat worried that none of the valid arguments listed for the SNDCTL_DSP_SETFMT ioctl seem to be for any kind of 24-bit format. Is there in fact any kernel support for 24-bit sound in general? Please CC me on replies; I'm on dialup and I can't cope with the traffic on this list. Many thanks Pigeon
