I have a Packard Bell iMedia from a few years back, which i now let my (young) daughters use. It originally had Vista so a few years back I put XP on it, and most recently Win7 x64.
Specs
- Windows 7 64Bit
- Core 2 4300 CPU
- 4GB RAM
- NVIDIA GeForce 7500LE(Included when purchased)
- 2x500GB HDDs set up in RAID0
- On-board Realtek HD audio
This problem only started when I installed Win7 x64. When the computer is first switched on, Windows claims No Audio Output Device is Installed
, and when I click the speaker icon on the toolbar(to run the troubleshooter), it tells me that there is a problem with my audio device, and that hardware changes might not have been detected(see below). Here is the sound devices registry log. At this point there is no audio device in Device Manager, not even a Sound, Video and Game Controllers
section.
Troubleshoot Report
When I put the computer to sleep then wake it, then do a scan for new hardware, it appears and seems to work fine.
What is the cause of this problem?
Or is there a workaround that doesn't involve puting the computer into sleep state?
