Hopefully someone can help me out successfully connecting my PC to my Bravia 40" LCD [KLV-40X350A].

I have no problem getting an excellent video picture over DVI - HDMI.

This doesn't carry an audio signal though so how do I get the sound from my PC to play through the TV's speakers?

I'm using the PC's onboard sound currently, which has 5.1 outputs [being used for the PC's Logitech speakers] and an SPDIF out.

Anyone with bright ideas?
