While this should in theory work, and I believe customers have done this with the MSP430, we do not have any information on how to interface the MSP430 to our audio devices. If this is something that would interest you, please reply to this post so we can judge the interest out there for such an app note.

I definitely need to get a 4kHz PWM signal on a pin which will sound a buzzer/alarm. I'm using MSP430f6723.
I'm searching the other solutions, but the rates that are being used are much, much lower.
In reply to Mechi Fendel:
There are a couple app notes out there describing how to do audio on the MSP430. If you can't find them, I suggest you post a new thread in the MSP430 forum.
