By definition, VUDU only

By definition, VUDU only streams stereo sound if you are using the SD service tier (which is all that is available on the PC).
As far as I am aware, this information has not changed for the PC:
Today, we cannot use WMDRM to deliver AC3 or DD+ audio, which means that only stereo (delivered via WMA) is available. PCs and Macs decode the WMA, and CE players also transcode to PCM for digital connections to receivers. We could technically include multichannel audio using WMAPro, but essentially no receivers are actually capable of decoding that.
