Connecting Sennheiser wireless headphones to Samsung TV using HDMI converter box. Went wrong somewhere

Hey everyone. Not sure if this is the right forum. If not, please do move it to the appropriate one or let me know where to move it to

So, here's what happened: I got a Roku for Christmas and I just wanted to hook it up to see how it worked. I don't have cable on my TV, just a BluRay player. I should mention that, since there was no way to directly hook the Sennheisers up to my TV, I bought an HDMI converter box, which I plugged the red and black audio jacks into, as well as an HDMI cable connected to my TV. Anyway, I unplugged all that to see how to set up my Roku, but I'm not quite ready to stop using the BluRay player completely. So I hook everything back up... and I can't use the headphones to hear audio anymore.

It's really strange, sometimes they won't even charge, sometimes they will. The audio is coming out of the TV speakers now, instead of the headphones. Try as I might, I can't get audio out of them. At least, audio from my BluRay player. Recently, I think I've been picking up TV audio, but it's audio from a program that isn't even currently being viewed on any of the TVs in the house.

I've moved cords around, switched plugs, unplugged everything and plugged it back in. I've looked for menu options on my remotes (I know on some TVs, you have to mute the speaker audio to get audio out of the headphones). Nothing works, and I don't even know what I did wrong.
I was able to connect the headphones to my PC and got audio out of that, so I have no idea what the problem is

Can anyone please help me or provide any clue as to what I need to do or fix? If you need any more information to answer my question, just ask

Thanks for the help

Oh, and the TV is a Samsung, model number LN32D403E4DXZA

This is a site primarily for professional audio as used in live events and similar purposes. It's unlikely you'll get much in the way of help here, but I'll offer this: if they don't charge up, you should be talking to Sennheiser.
