I can't get the sound on the tv tuner app to work on my AIW 9600. It used to work until I updated to the newest catalysts. I run the system check and it says my WDM driver isn't installed. But it is, its listed as working in the device list. I have followed all the instructions on ATI's page, including those for trouble-shooting this particular problem. I have installed drivers in different orders, installed older drivers, uninstalled and reinstalled a million times, everything! HELP!!!!!!
