It's funny that it would stop working the day I had plans with friends to play Amnesia: The Dark Descent all night. Oh, well, though.
So, here's the problem: I installed the card, and initially had no sound. After browsing the forums here, I came across the a very useful thread here
. I followed all the steps that were suggested here - I upgraded my ATI Catalyst, made sure the HDMI sound driver
was installed, and even tried the Realtek driver suggested on page 2. That one finally worked! This morning when I turned my computer on, everything was fine and dandy until I installed a couple updates from Windows Update, and then upon reboot, there was no sound.
None of the updates had anything to do with audio drivers
. They were the malicious software removal tool, an ethernet update from athros, and an update for windows x64 systems. After having no sound, I retried all the steps, but this time to no avail.
Windows 7 Ultimate x64
ASUS M4A78T-E motherboard
Phenom II x4 955 Black Processor
Radeon HD 5750 GPU
4GB G. Skill RAM
320 GB Western Digital HDD
***EDIT: Apparently, the Update for Windows x64 (KB976422) disabled my sound driver***
