I have been tasked with getting sound to work on a couple
different embedded x86 boards that contain the ESS1869
audio chipset. (in QNX6.2)
I was prepared to write the driver from scratch using the
Audio DDK but there is no sense doing more work than
The chipset is “Sound Blaster Pro” compatible, but it
seems with some caveats. Most spefically the QNX 6.2
docs for deva-ctrl-sb.so states:
“Some sound cards listed as being Sound Blaster compatible
default to another mode (eg ESS18xx series, …). These
cards will not work with this driver.”
Could someone explain to me what “another mode” means?
The tone of this comment would lead me to believe that
someone close to this driver has direct knowledge of what
is missing to support the 18xx series. It would save me
a fair amount of work if someone could point me in the
I have been told that I should be able to obtain the
deva-ctrl-sb.so source through other (more appropriate)
channels if it would be a useful starting point.
So I basically want to know:
- What makes ESS1869 not work with the current driver?
- Would dev-ctrl-sb.so be an appropriate starting point
to writing a ESS1869 driver?
