I ordered the following graphocs card: Sapphire Technology ATI Radeon HD 5450 650Mhz 1GB DDR3 PCI-Express DVI (Low Profile)installed in a pretty standard HP desktop with windows XP service pack 3.It works fine as expected using the HDMI port. But I need to leave my computer on constantly and when I return to my PC after a nights sleep I find the sound no longer works.when i check the sound settings I find they are all greyed out. the AMD audio is listed in the device manager and listed in the audio settings but it is greyed out. I can make no changes to my audio settings at all, not even able to select a different audio source.I cant find what is causing this. I have disabled all power management settings and removed all scheduled tasks and updated the video drivers.has anyone had or seen anything like this, its very frustratingthanks
