What cards will NOT be supported by ALSA? Why not?
Creative Sound Blaster Live! Aureal Vortex RME DIGI (Except DIGI 9652) Yamaha SW1000xg Yamaha YMF744B Yamaha YMF724 Creative Vibra 16X TerraTec Xlerate + DMX (Aurreal Vortex) ESS Maestro1/2 Some manufacturers view the programming specifications for their hardware as a trade secret and will only supply information if a developer signs a NDA (non-disclosure agreement), which says that a developer will not tell or disclose the specifications to anyone. Source code inherently discloses these specifications and therefore cannot be released to the general public. This is not acceptable to the developers of ALSA or to the spirit of the GPL, so drivers may not be developed for these cards as part of the ALSA project. Some of these vendors (specifically Creative Labs) or others may provide a binary-only module for their card for ALSA, but these modules will not be distributed by ALSA or SUPPORTED BY THE ALSA DEVELOPERS.
