I have sound! Thanks for all the help. What I did, after I read some the links provided, I decided to format another SD card and reload all my programs and I got sound. Then I compared the two SD card files and found that the original card had a file called AIY Project Voice, this program overwrote some of the files and change the parameters for output, apparently my grandson downloaded it thinking he was helping. Now all is good and I’ve learned a lot with every ones help. Thanks again.
