    You may need to recalibrate the radio to the esc. This can be done by following the instructions in the picture below.
    Once that is done power everything on including the oba module and follow the instructions in this next picture.
    If that doesnít work maybe some others will chime in.

    It's been quite some time since I've dealt with a Traxxas esc, tho if memory serves blinking green means your neutral points are off.

    Hi, i have same problem. Slash 4x4 VXL. It is problem with last update traxxas link (20.12.2018) .
    Everything works fine, i drive normal. But when i updating, sound OBA not working and parking mode on receiver not working, only drive at the top and bottom positions.

    I'm having the same problem as well. I bought a Slash 4x4 with OBA then just recently it just stopped working but the green light was blinking before on the sound module but now it's solid green. I still get no audio.

    Mine has the most recent update but I have a castle system installed and an external bec and aftermarket savox servo on my slash 4x4. I just tried mine and the park/neutral and drive works like normal with sound. I have audio but thatís where it goes downhill. Through the speakers I can hear my servo motor noise amplified through the speakers in the body. Really weird...

    Are you on android and got an update for the TraxxasLink app or what? I have apple and I donít see any update for the TraxxasLink app yet...

    ***EDIT***
    I just went to the google play store and the android app is updated already. I hope they release the update for apple soon!

    Yes the update worked. You have to update the App first for Apple users, not sure about Androids. Thanks everyone.

    Nothing seams different other than the receiver temperature gauge doesnít work now. The receiver voltage reading is fine, just not temperature from the receiver temp sensor. My temperature sensor from the telemetry expander works tho.....

    For what it is worth, this helped me a great deal!! Here's the issue I was having:
    I no longer have the speakers for the slash. They get beat up and come apart and at $35 EACH there's no way I am going to bother to replace them.
    I pulled the OBA from the Slash and got a hair brained idea to put it in my new TRX-4 Blazer, just for the Hedes of it. I connected a speaker from an old toy.
    Everything worked except of course no 'neutral' because I refuse to give up the two-speed or one of the lockers ... and the sound was not responding to 'reverse' at all.. as in, it would rev when driven forward but nothing in reverse and would even eventually turn off, while reversing.

    Based on the pic in ChargerMan's post, I reset/recalibrated the sound module, and now it's all working just fine, just of course no 'neutral'.

    Thank you!
