RCA Module 13.2 as a tone generator?

  • Hi,

    I picked up a RCA Module 13.2 and attached it to my Core2. I was able to generate tones (programming in arduino) using the internal Core2 speaker, but when I configure it to use an external speaker I'm not getting any signal out of the RCA Left or Right Audio outputs.

    It could easily be a programming issue, but wanted to ask if anyone knows if this module can be used to generate tones?
