I got yesterday Radeon HD 2600XT Super card, and I was happy half a day.
After that I discovered that the voice disappeared.
It happens, as I understood, because a new audio driver has been installed (also my motherboard has audio Realtek onboard):
ATI Function Driver for High Definition Audio â€“ ATI AA01
Device type: Sound, video and game controllers
Location: Location 65635 (Internal High Definition Audio).
I tried uninstall it, but then after Restart, itâ€™s again Hardware discovered.
So I just disabled this driver, and then Iâ€™m able to get audio via my Realtek driver.
It would be OK, but sometimes I get black screen.
My PC: GA-P35-DS3 (rev. 2.0) motherboard,
IntelÂ® Coreâ„¢2 Duo Desktop Processor E6550,
Kingston DDR2 1 Gb 800MHz CL5
