Okay, this is VERY odd... I love FS2004.. all few minutes I can TAXI in it. When I change a view a high pitched elongated *BEEP* is blasting nonstop. Kinda like the hospital flatline sound. Anyway, this high pitched sound takes over every other sound on my system, even after I close FS9 and open up an mp3 or something of that sort. NO OTHER SOUND WORKS ON MY COMPUTER THEREAFTER. I've tried the logical thing; turning off my ALTEC THX 4.1 speakers and then turning them on again, but the ringing is still there. The only way I can get rid of this annoyance is by restarting the whole computer. I've tried uninstalling completely and reinstalling FS2004 twice now, and say after the fifth time I've changed a view (by using SHIFT+S or S), the high pitched ring comes up.. I should add that after the ring starts, FS slows to nearly .5 fps.. Specs: Dell Dimension 8100 Intel P4 1.7GHz 80GB HD 512MB RAM Santa Cruz sound card (don't know much more than that) nVidia GeForce 2 Ultra 64MB w/ patched 40.52s drivers DirectX 9b (the newer version) However, I can still fly, just as long as I stay in one view; cockpit. I'm scared to even switch between the cockpit and virtual cockpit (vCockpit for better view of my surroundings) for the fear of that ring starting up.Anybody have any ideas??Regards,Tim

I also have a Santa Cruz.I've been able to eliminate the problem on my system (WinXP Home) by going into the "DirectX Diagnostic tool" which is located in (Accessories/system tools/system information/tools) and changing the "hardware acceleration level" within "SOUND1" from FULL to BASIC.Not sure, however, how this might impact the sound on other Direct X dependent programs at this time. So far so good.This is a band-aid fix, I think we will need someone to come up with new drivers.Martiro

I had the exact same problem and solved it with a driver update. I downloaded the new drivers and the problem seems to be fixed as everything sounds fine now. You can go to http://www.turtlebeach.com/site/kb_ftp/585ftp.asp to get the new drivers (sc_4193.exe). They are unsigned so if you have Win XP you'll get a bunch of warnings but they seem to work ok for me.Jon

Thanks guys, works great now!Regards,Tim
