I understand there has been some trouble getting ARC to operate correctly on this model, but the threads discussing this are about a year old so I'm praying theres been some development since.

I have the cabel plugged into the ARC jack on my tv, and that goes to the OUT jack on my Onkyo HT-R590. I set my ARC settings on my receiver, so I think it's all squared away on that end. But I still cant get any sound coming from my tv. I'm not sure if theres a setting I'm missing somewhere (it's not like this tv came with a manual), so is there any advice or troubleshooting you guys can walk me through?
