I am having a bit problem with HP Pavilion DV4-1123US. It has windows xp on it. I had upgraded to Windows 7 recently. After upgrade the hdmi has stopped working. I am not able to get any audio from that. I restarted the pc a number of time and I am able to get video, but still there is no audio. What should I do to fix this thing.

Try to re-install the hdmi adapter and check back. I think that will help you to fix the problem you are facing. For that you have to go in Device Manager. then you have to right click on the hdmi audio device and uninstall it. Later on restart your pc and install it back again. This will fix the problem. You have to find the right drivers for that. If this does not work then try to find the latest motherboard drivers and install that on your laptop. This will surely work.

You had upgraded so due to old drivers you are facing the issue. You have to simply go ahead with driver installation which will help you in fixing the problem. The second thing you can do is try checking with some different cable. There are ample of them available. Buy a new one if possible and try to connect the laptop through that. See whether you are able to get proper output or not.
