No sound from monitor when connecting HDMI from XFX Radeon 7870 HD

[leenathan24]

Right now I am using DVI from my XFX Radeon 7870 HD GHz Edition to my monitor (which doesn't give audio output, as far as I know). But I want sound as well. Problem is, when I use an HDMI from my GPU, not only is the picture proportion smaller than the actual screen size, there is no sound. It used to be that I could connect HDMI from the standard motherboard port to my monitor and I would get sound. Now that doesn't even work. I am up to date on my graphics driver using Catalyst from AMD. And I recently checked and was up to date on my other system drivers like Realtek. What could the issue be?

Go to contol panel> sound> right click on the monitor and pick "set default device". Assuming that monitor has speakers, it will play sound now. As for the picture being too small that's a scaling issue. It's an option in CCC. I can't think off the top of my head where it is in there but I recently had to change it too.

Here is what happens. I've been here before (probably should have said that):

Also, when I plug headphones into either my keyboard or desktop I get sound, but that's the only time.
