Does hdmi to dvi cables provide Hd audio and video signals, just like hdmi cables?

I have a older 3yr old RCA hdtv (dvi) input and a new onkyo HDMI receiver(hdmi output). If i got the Hdmi/dvi cable will thaT PROVIDE MY AUDIO AND VIDEO SIGNAL?

To what? You can use a DVI cable with HDMI-DVI adapters on both ends between two HDMI devices and you are doing HDMI with audio and video. But if one is just a DVI device, then no, video only.

If i got the Hdmi/dvi cable will thaT PROVIDE MY AUDIO AND VIDEO SIGNAL?

No.
