We use a SCADA system (RealFlex) that uses the internal speaker to give
audible alarms for the operator.
Since we need to move the console (but not the PC) away using a multimedia
extension device, we need
to route the sounds to a set of speakers, what sound card will work with QNX
4.25? Is there an easy way
to tell QNX to route ‘beeps’ to the sound card instead of using the internal
speaker?

Gabriel

How easy this is really depends on exactly how the RealFlex code
generates its “beep” noises.
If it is doing something like writing a BEL (^G) character to a terminal
device, then you might be able to intercept whatever terminal device it
is using, and re-route any beeps to a sound card. (To find out will
probably require information from RealFlex.)
If it is hitting the hardware directly (explicit code, or using something
like the sound() function) then it is much trickier. I can see that
requiring either cooperation from RealFlex, or really long wires
for your PC speaker.

Thank you for your reply, I will try to get this information from RealFlex.
In any case, what sound card will work with QNX4? What drivers are there
available?
