Hello Everyone. I have been poking around here for a week or so, trying to figure out my problem. To start off, I have a Acer Aspire X1200. Notorious for HDMI problems. When I first got the pc, I could not get any video signal once windows came up. Fixed that by un-installing driver in safe mode, re-installing and finally got VGA video signal. But no HDMI video. Fought that for about 2 weeks and finally poof, I have HDMI video signal. I have a nVidia Geforce 8200. I still do not have HDMI audio. I have read in many previous threads to install a previous nVidia driver, but with mine, only the newer one would give me a video signal. I have tried installing the recommended Codec from nVidia, but to no avail. Un-installed, re-installed, etc. If I try to roll back the driver, it totally removes the driver all together. I guess from un-installing so many times. So I reinstall. Under nVidia driver, it says cable unplugged or something of the sort. Obviously, it is plugged in, because I have a video signal. Under my control panel- sounds, the driver shows up, but I cannot even Enable the thing! It also has a Realtek HDMI audio driver, but I get no sound with that enabled either. Has anyone gotten their X1200 HDMI to work?? I keep reading threads about the problem and the majority cannot get everything to work correctly. The ones that say theirs works, thats all they say. Lucky dogs. Can anyone help me with this problem? Tech support has been little to no help. I might also mention that anything in the nVidia Control Panel Help it tells me to do, is not in the actual control panel. There are no Audio options. Having a limited knowledge of computers, I have come a looonngg way in the past year. I have managed to fix all of these issues on my own, until now. I am at the end of my rope, no more tricks up my sleeve. Please, please someone help. I know there are smarter people out there than me.
