Where can I get the TRRS cable for the Human Interface board?

I bought a 4 pole to 3 RCA plug A/V cable from Amazon but when I tried it using the TV graphic demo and connected the yellow, red and white RCA plug I get no picture. I can get a picture on red and white if I pull the plug out a bit. It appears that cable is not wired right for the HIB. Is there a good source for the cable?

    I just checked the cable with my meter and it shows the ground on the outer ring rather than the sleeve so it definitely is the wrong cable.

    Hmmm... No answer. Does this mean there are no cables that work on this board? If so what are people using this board for? I was planning on using the audio and tv outputs so I'll probably have to buy a plug and clip off the one I had on the cable I bought and rewire it so it works.

    Interesting, I lost sight of this thread but came back to it to look for answers, so I was surprised not to see any. I am checking with a colleague who deals with all sorts of cables to see what he can come up with as I have two that need TRRS cables.

    wba, let us know what you find out. I rather get a ready made cable especially since the plugs will run about $7-10 due to shipping costs and that was more than the $5 I spent on my cable.

    I know the documentation explains what the TRRS cable is but most sellers don't give the pin out of cables. Also I talked to a fellow propeller friend and he says the jack on the HIB may be connected wrong.

    I bought one of these myself several months ago, but haven't had any luck (yet) in figuring out where I bought it (!)
