Thread: No PC speaker audio from Teensy 3.2

  1. #1

    No PC speaker audio from Teensy 3.2

    I have my Teensy 3.2 programmed with a simple sine generator (Audio Library) connected to the Usb output. On my Windows 10 computer, I have a program called "Soundcard Scope". I have all the Input setup options set to "Digital Audio Interface Teensy" and all the Output setup options set to my PC sound speaker output. I can receive input audio from the Teensy and see it on the Soundcard Scope but I don't get any output on the PC speakers. All other PC sound functions work. If I set up the PC Soundcard Scope's internal signal generator to output a tone, I do hear it. I've tried deleting and reinstalling drivers and moving to a different port.

    Did you try enabling "listen to this devive" (or similar) on the teensy soundcard settings? It sounds like that's what you are looking for.

    Control panel>sound>recording>teensy>listen to this device checkbox. (Guessing without looking).

    This will add latency.
