What happened to your receiver setup?
Unfortunately, my receiver has no headphone jack output (I have the ubiquitous Sony HT-SS360), I so I'm left with using an RCA to stereo-mini female converter for my TV and PS3 (PC has headphone jack from soundcard)... which works fine enough, except there's no way to control the volume doing it that way from my TV or PS3 (thankfully, the volume level is fairly mid-range). So now, I've got three stereo-mini female jacks all sitting conveniently next to my receiver, which I swap to and from depending on what I'm using when I want headphones, lol.
I'm guessing there isn't such a device that would go between the HDMI-in on the TV and the HDMI-out on the receiver (i.e. two HDMI female ports) that would add a headphone out? If such a thing did exist, I'd imagine it'd be quite pricey.
