Thinking of purchasing a sonos beam for a 2008 panasonic TH-42px80 which does not have an arc enabled HDMI port. It only has standard rca audio out (red and white). I mainly use a 2TB sky+ HD box for my viewing. What would be the best way to connect a beam? Some options could include:
If option 2&3, and recommendation for a converter make and model?
				
			- Connect optical (toslink) on sky box to optical on beam (optical to optical)
 - Connect rca audio out from TV to HDMI on beam (using rca to hdmi converter)
 - Connect rca audio out from TV to optical on beam (using rca to optical converter)
 
If option 2&3, and recommendation for a converter make and model?
