I have just set up a new system for FS2004 which incorporates Realtek AC97 on-board sound. However I get a wierd problem with my sound, a distorted buzzing type of interference only when using the mouse click on most of the FS2004 menu screens. I have no experience with on-board sound since all previous systems included separate sound cards without any issues.Here's the really annoying part. I can fix the problem by turning down the hardware acceleration in Dxdiag, or using the Windows XP Control Panel under Sounds and Audio Devices, but Windows keeps turning it back up to full acceleration on very regular occasions eg. rebooting, or even going from windows mode to full screen.Shouldn't it be possible to permanently set the sound hardware acceleration to a lower setting??? I hope I'm missing something very basic here.System Specs: Gigabyte GA-K8N Pro_SLI, AMD 64 4000, 2 gig Ram, 7800GT Video,Win XP SP2.Warren

Go to Start,Run and type in dxdiag,and try to adjust in the sound section.http://forums.avsim.net/user_files/141407.jpg

Thanks Jim, but that is exactly what I keep doing, but for some strange reason, it keeps changing back to full acceleration, often after booting up and occasionally when the PC is in use. I just can't seem to get it to stay at reduced acceleration ??????? Warren

There's a second place where you can adjust hardware acceleration (you didn't think MS would make it so simple as to have only one place to adjust, did you?).Click on Control Panel> Sounds, Speech, and Audio Devices> Sounds and Audio Devices> Audio> click on the "Advanced" tab in the "Sound Playback" section> Performance> then see the slider for "Hardware Acceleration".Cheers,Greg

Thanks also Greg,but YEP, thats the other place I had tried adjusting it, without it staying there. You would have thought one, or both of these settings would set it permanently at reduced acceleration, but NO!! I can't get it to stay reduced. Obviously, some other program, or maybe the driver, keeps changing it to full acceleration. Very frustrating.Warren

Yeah, you've got something going on in the background. You can try this to monitor what's going on and track down the culprit. It's a powerful tool thay may take a while to figure out, but hopefully it will get you pointed to the problem.Hope this helps,Greg
