    Have you checked the audio output selection? Had the same issue it’s my Pi until it found that it defaulted audio output to HDMI. I don’t recall which version of the OS I was using but I could not get it to send audio to the jack. Ended up using an HDMI to VGA adapter with a 3.5 mm audio jack.

    You need the proper connector, 4 conductor. The video is on the same jack.

    Do not go by color code, Check the cable with a ohm meter.

    You need to use headphones or a amplified speaker.

    A cheap USB audio fob adapter will work if you want to use USB to feed a amplified speaker.

    Have Fun.

    yep. did the raspi-configre or what ever it was .. so many com lines ago lol ..
    i went back in the settings thru the latest raspbian. got it working... but yep i came across that on the wb pages...

    tho the idea of gettin a usb set might be a way to go not sure now..

    iam tryin to make this very very portable for digi. but when i wanna tinker lol at home like to be able to plug in easy..

    iam posting some images below.. as this post is from the RPi...

    if i can get the flash workin i might be all set lol ... grrrr but i have a B+ guess i might have to grab a RPi3 to get flash working..

    did the gnash with chromauin and firefox. only one site doesnt work. spectrum cable.. grrrrrr

    I guess I did not know your Pi version.

    The Pi3B uses 3.5mm connector with audio and NTSC video.
