Audio output via DVI-D port? GA-A55M-S2V

[mikeinside]

Hello Gigabyte community,

I would like to use the GA-A55M-S2V in a HTPC, and connect it to a 1080p TV via a DVI-to-HDMI cable. My question is, will the motherboard output an audio signal via the DVI-D connector? I do not want to have to use a separate cable for audio. If it will not, will a more advanced motherboard with a HDMI port (such as the GA-A75M-D2H) do it?

I contacted Gigabyte directly and was told:
"Only HDMI port and Displayport support for output audio and video at the same time. Due to you used DVI-to-HDMI cable, we can not promise it can output the audio properly."

He didn't say it definitely won't work, but he also didn't say it would 

Better not risk it, guess I'll have to pay the extra $30 for the model with an HDMI port.
