These steps most probably apply to you, regardless of 'sound card'.
They apply to
SB8 SB16 VIBRA16 AWE32 PCI128 AWE32 AWE64 and just about any card claiming to be 'soundblaster compatible' The 'soundblaster' is the generic, set in concrete sound system for IBM PC's.
Other chipsets such as crystal audio, do in fact have their own sound drivers. BUT, these steps are specific enough for you to fill in the blanks appropriately.
There are two (2) write ups for soundblaster. BOTH refer to the top of the line AWE64. Simply ignore any reference to the AWE (about 2 sentences) and utilise the rest of those documents to setup YOUR soundcard, painlessly.
PCI and on board AC97 sound devices are best supported under
linux by using the commercial OSS drivers available here
