A client of mine had me troubleshoot a problem on one if his Windows Vista laptops running PowerDVD DX 8.1 to play DVD’s from the internal DVD drive. I have used PowerDVD in the past but it has been awhile so I wasn’t exactly sure what the problem was right away. He said that one of his sons had been messing with the *function button along with the number keys at the top and the sound stopped working. I looked through each of the possibilities and nothing made sense that could have caused the sound to quit working.
After launching PowerDVD DX 8.1 I did verify that sound was not working but sound was working with every other application including Windows Media Player, Quicktime, Flash Player, and other media applications. I went through all of the settings for PowerDVD and even used the button to change everything back to default settings without any luck.
Next I decided to see if there were any updates available by clicking the Online Update button as shown below and sure enough there was an update.
The Online Update button downloaded a minor update which updated PowerDVD DX 8.1 to PowerDVD DX 8.2. Not that it will require you to uninstall PowerDVD DX 8.1 before upgrading. Uninstalling version 8.1 is part of the upgrade process but it can be confusing as it asks if you want to uninstall PowerDVD DX 8.1. Just make sure you agree to uninstall the old version or the upgrade will fail.
After the upgrade everything worked properly and so I shutdown the laptop to return it to the client. While on site with the client I booted the computer to show that PowerDVD was now functioning with sound. When I attempted to play a DVD it complained of Region Encoding. for some reason it required another reboot and an Internet connection before it started working properly.
Also note that even though I upgraded to PowerDVD DX 8.2 which was the latest major version number there was still a software patch that needed to be installed to version 8.2 before the code was at the very latest and greatest. To install the patch simply click the Online Update button again and follow the instructions. Once the process begins you will see it download the latest patch from the PowerDVD servers as shown below.
Once the patch is installed you will not be required to reboot but I would suggest doing so just to make sure you don’t end up in a situation as mentioned in the first portion of this article. If you are having trouble with the sound but there is not an Online Update available to your version of PowerDVD DX then its probably beneficial to uninstall the current version and then reinstall it to see if that resolves your issue with PowerDVD’s sound. Make sure before you uninstall the current version of PowerDVD that you already have the PowerDVD installer. If you continue to have issues you can visit the Cyberlink web site and see if there is more information related to PowerDVD here.
