Hi all, relatively new to the Pi in general,am running Raspbian Jesse and had audio coming out of the 3.5mm jack when tested. Then I installed a camera and Pieface 4 relay board that connects to the GPIO connector. Since connecting that board and adding the required files....both the camera and the relay board work fine but I'm no longer able to get audio out of the 3.5mm jack.
I've tried several times using terminal to raspi-config to Advanced and Audio and saving the change then rebooting and typing sound-test and the error I get is "Command Not Found" What am I doing wrong....?? No audio any idea's please
