Has anyone seen any third party drivers that will work with an Ali AC’97
sound card? Or had any luck getting another driver to work? I would swap
for a different sound card, but it is in my laptop. Currently QNXRTP
supports everything in my laptop except my sound card. All things
considered that’s pretty good.

There is major misconception created by all the vendors publishing specs
with lines like ‘AC97 compatible’ sound card. People start to think
there is such a thing as ‘AC97 sound card’.
In reality a sound system includes digital (PCM) part and analog part,
called mixer or codec. AC97 is Intel’s open specification for analog
part. There are other specifications for analog parts, like Asahi-Kasei
and some systems use them. Some systems have totally custom analog part.
There is no standard whatsoever for digital part.
When you say your card is ‘AC97’ it only means you got standard analog
part. That is good, because driver for it would utilize standard ac97.so
shipped with QNX. But driver (it’s digital/PCM part) still has to be
written.
That is not very hard to do, when you have specs. It is also possible to
use Linux ALSA driver as ‘specs’. I’ve done that with ESS drivers, you
can look at the sources and figure how. Or buy me a laptop with Ali
chip, I’ll do the driver then
