I was trying to figure out how to play a .wav file through the netduino. Is it possible? I had an 8khz mono wav and was trying to play it through the PWM on pin 5. Seto seemed to think it might need a DAC. I know the Fez can do it as I've seen a video. Any info/explanation would be appreciated! Thanks!

I would have to agree with Seto, you'll probably need a DAC. The microcontrollers that are used by the FEZ line have a built in 10-bit DAC which is what I believe would have been used in the video you saw.

IIRC, FEZ does have a DAC since I seem to recall a post on TinyCLR today with someone asking for help on it, but yes, this is something you really need. I generally don't suggest things unless they are a necessary component

Could you use PWM to accomplish the same thing (perhaps with an inline component or two to translate the digital signal into an analog voltage)? Also, there should be external DAC chips that could be easily added to your project ... Chris

Thanks Chris - I appreciate the reply. I'll look into the adding a dedicated DAC route.
