anarchosax hardware that is “confirmed” to work (as in the case of my other sound card)
The specs. for the old (introduced 2013) Audigy Fx states the chipset used is a Realtek ALC898 but, yours is an ALC899. Marketing names can be tricky. In this case, the PCI ID is also the same, but the chipset is different.
BTW, Creative also says, in the Audigy Fx User Manual, that if you have an onboard or another card present, you should disable that first. Can you try that?
anarchosax [...] but that doesn’t mean that we should have to jump off at the deep end
More like paddling in the kiddie pool, in this instance.
anarchosax the first thing needed after an install is to compile a kernel.
Can't be helped: The complete set of people with commit access to NetBSD has precisely 284 names. These include all developers: kernel/lib/docs/www/pkgsrc/retired/dead/occasionally active people. The number who've actually worked on audio stuff is probably just 2 or 3. How much audio HW would they have access to?
