How to connect wireless headphones to Panasonic Viera TV with Surround Sound

[zchamps]

I have a Panasonic TC-P42S2 Plasma HDTV with Panasonic Blu-Ray Sound System SC-BT730.

The TV only has one Digital Audio out, which is being used by the Surround Sound System.

I would also like to use a wireless headphone, but notice there is only ONE digital audio out on the TV.

I purhased a Toslink Splitter and a Digital to Analog converter (since my headphones are analog)

and

I get no audio to the wireless speakers, but I do get audio to the surround sound. I looked on the back of the surround sound system and do see a unused AUX port.

Any ideas on how to get this to work? Do I have the right converter, or is it possible the converter is bad?

Would a toslink amp make this work? OR

Would a powered optical digital audio splitter work? From TV's Toslink wih cable >> powered optical digital splitter >> connect toslink from surround sound to splitter >> connect Toslink cable to the Toslink to RCA to splitter >> connect RCA cable to wireless headphones ??
