Sound Card Disappears with Hyperthreading/Dual Core Enabled
I have experienced the following symptoms with Hyperthreading/Dual Core enabled in BIOS:
- Volume Control icon missing from System Tray
-The sound card disappears from Device Manager
- No sound card listed under the Audio tab of Control Panel - Sounds and Audio Devices
- Reinstalling the audio drivers resolves the symptoms until the system is rebooted
Upon disabling Hyperthreading/Dual Core in BIOS setup, the sound card problems disappear.
We have 10 - Dimension 4600 systems, 5 or more which have displayed these symptoms.
We have 2 - Latitude D620 systems, and are purchasing 80 more, 1 of which has displayed this problem.
We are running Windows XP SP2 with the latest updates, and all systems are using the onboard audio.

Yes, it has a corporate imager. But, I found the solution for it on your forum. The solution is to disable beep in the device manager by allowing to see hidden devices and selecting beep under non-plug and play devices.DELL-Jimmy P

NiSuSIf the image you are using was created on an older system you may have the wrong HAL loading, starting with the D610-D810 and the newer Optiplex's the OS is using an APIC HAL, vs a PIC HAL used on previous systems.Also if you have a mutiprocesser HAL you can't just turn Hyperthreading off because it won't switch back to a uniprocesser HAL, according to Microsoft you have to reinstall to get the correct HAL when you do that.I have had luck using the method below to change HAL's but like I said above Microsoft recommends reinstalling.If you have a I386 folder on the hard drive from a command prompt type:expand C:\"location of I386 folder"\Halaacpi.dl_ c:\"Windows installation folder"\system32\HAL.dll
This will overwrite the hal to APIC, you then reboot, it will find new hardware and ask you to reboot again.
If you have a mutiprocesser system or hyperthreading CPU Change Halaacpi.dl_ to Halmacpi.dl_
If you do not have the I386 folder on the hard drive you will need to extract the files from the installation CD.
Note: This method is not supported by Microsoft, is not guaranteed to resolve any specific issue and could very well leave you with a system that will not boot and need to be reinstalled anyway.
The steps above will replace a PIC HAL with an APIC HAL, if you use it on a system that does not support APIC you will have to reinstall.
- We purchase 30-60 systems of the same model, same spec's,at a time.I leave the Dell installed Windows XP Pro OS installed and do theWindows updates, install Office and updates, and other applications,ie. Adobe reader, Winzip, etc.I then create an image of that system, and use it to image the restof that system model.Sometime later I may create an image from scratch, for a particularsystem model, reinstalling the Dell provided OS, drivers, updates, etc.The Dimension 4700's began to exhibit the problem quite sometime after they were fielded. I disable hyperthreading in the BIOS,and the sound reappears.I am most concerned about the Latitude D620, we have about 60of them being procured now.
