That might be on the card providers website for public consumption, or you might be able to get it from the card provider by signing a non disclosure agreement, or the developer that wrote the driver for alsa might be able to answer your question about the maximum value. A long shot would be to reverse engineer the window's driver looking for the value. ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
