I've never heard of a DVI connector that transferred Audio.
DVI connectors transfer video signals and can be analog or digital (or both).
You will have to do one of two things:
a. If the motherboard has a good audio output like SPDIF and you can plug that into your TV, then that might transfer the audio over. It depends on the TV, though: some TVs will only accept a separate audio signal if you put the TV in "PC" mode - in HDMI mode they expect the audio to be in the HDMI connector with the video signal.
b. Find an adapter that takes audio from your computer and "adds it" to the HDMI cable.
[Edit] You may find it cheaper to buy an inexpensive ATI/AMD video card that includes an HDMI audio driver and you connect it directly to the TV with HDMI.

I did some quick Google research, and DVI audio support for Intel integrated graphics seems hit and miss. One theory is the function is supported by the IGP but may be broken by the implementation.To promote interoperability between DVI-D and HDMI devices, HDMI source components and displays support DVI-D signalling. For example, a 1080p HDMI display can be driven by a single-link DVI-D source - since HDMI and DVI-D both define an overlapping minimum set of supported resolutions and frame buffer formats. So, DVI-D devices output HDMI signals, many including audio, (examples: ATI 3000-series and NVIDIA GTX 200-series video cards),[9] and some multimedia displays input that HDMI signal, including audio, by using a DVI to HDMI adapter. Exact capabilities vary by video card specifications.
I am looking to get a cheap LGA 1155 system and my main question is : in the absence of an HDMI port, will the DVI connector transmit the sound too, to get it to the TV over an DVI to HDMI cable?
