I'm looking to connect my W520 to a tv for watching movies. The video is all set up with a DP to HDMI adapter directly from the laptop to the tv. The sound, however, must pass through a receiver first. The receiver only has RCA inputs - it's quite old. I know the hypothetical setup would definitely work because I have a cable tv set top box connected that way.
What's missing is an external sound card that is:
- compatible with the w520
- capable of outputting 5.1 surround sound
- capable of connecting via RCA, be it through an adapter or not
Can anyone recommend a reliable external sound card for the job?

Now that I've done a little more testing I have a more specific question. My receiver uses Dolby Prologic II, which means the front center channel is virtual and the rear channels are embedded in the usual two stereo channels.
I tried using a 3.5mm-to-RCA adapter before but it wouldn't even output stereo. Only the left channel was being sent to the front two speakers, nothing to the rear.
Is this the fault of the adapter or the sound source? In theory, I don't need full blown digital 5.1 sound, so would I be better off buying an Intel WiDi adapter given that my ThinkPad is equipped with an Ultimate-N card and a Sandy Bridge i7, Or would that leave the rear speakers silent?

Have you tried one of these?
