My sound was working fine for months. I shut my pc down to go to a lan party... got there... no sound... Booted to XP instead.... Sound works..
When I got home... no sound in Vista....
Its not muted.
No errors in event viewer.
I have the following symptoms (besides no sound):
"Test" on Default Format results in: Failed To Play Test Tone
Media Player results in : C00D11D2 (generic cant access file)?
"Test" on speaker conf. results in: Failed To Play Test Tone
I had the Realtek Hi Def 1.75 drivers
tried reinstalling them...not fixed.
tried installing 1.74...not fixed.
tried new chipset drivers...not fixed
tried new video drivers...not fixed
Seems common on the web... yet not resolved yet?
KB930883 seems slightly relevant, except I do not have duplicate entried on the default format option.
My PC is as follows:
4GB DDR2 800
1.14TB HDD Space
Vista Home Premium x64
Mainboard EVGA i680 SLI
I am getting quite annoyed with the 64bit version of Vista.
Since I have installed it, I have had this happen and also at one point all 32bit applications were crashing (IE, Outlook, Everything). I had to do a repair install to fix that.
