I wouldn't expect any audio at all. DVI is not a connection type which typically supports audio. It is not part of the DVI standard. Some DVI connections do act like HDMI and carry both audio and video, but for the most part, this is not the normal. DVI was killed off a VERY long time ago. I think my last three laptops had HDMI on them and the oldest is about 15 years old. So, I'm not sure what you are working with, but you may need something else to get audio into things.
