Hi,

I have a CMI8738 Soundcard (onboard).

Does anyone know of a way of getting QNX to recognise this ot have a driver
for it?

Cheers

There’s no driver. You could port one from ALSA if you’re decent C
programmer.

Common Igor … there more requested than ‘decent knowledge about C’.
A good overview about the sound technology (PCM a.s.o) is also at least
neccessary.

I’ve started port of Maestro driver with no prior knowledge of sound
technologies, just vague understanding of how PCI DMA works in QNX.
Reading audio DDK docs gave me some ‘big picture’ and the rest was in
the ALSA source. It is not really all that complicated.

And, QSSL audio gurus are interested in broadening hardware support so they
are helpful with details and fine points.
