It seems that on landing I am hearing a strange sound besides the ground roll and reversers. I am using a Sound Blaster Audigy with the most current drivers. The sound I am hearing is almost like a cross between nails on a chalk board and a screeching-wooshing sound. I know strange, eh? If I press the Q key and turn off all sounds then press the Q key again turning the sounds back on it goes away. This only happens on landing. Otherwise, the sound is perfectly normal everywhere else in FS9.I will give a side note, that I recently reinstalled FS9. And for some reason, I had to reinstall my drivers to the sound card sometime afterthe reinstall of FS9. It seems that my sound card was not being seen by my computer. Reinstalling the drivers fixed this problem.Any ideas of how to fix the landing sound would be appreciated. I am looking forward to hearing your ideas. My first thought was maybe a corrupt sound on landing. Like a touch down sound effect. I listened to all of the individual sound effects with no luck of reproducing the screeching-wooshing sound. I looked at my direct x and ran a sound text, all is fine. Other ideas of what I might be overlooking? Anyone else have this problem before?Thank you for your tips.Kev

Well, that is strange. I would restore clock settings first, just to check, because that is the easiest to try.

Hi sometimes running dx9 again can help,if nottry dropping the sound hardware acceleration down to the 1 notch above the lowest settingstart~settings~control panel~sound~audio~advance~performanceor use the slider in dxdiag soundwhat happens is there are a lot of small sounds that make up the ground roll one gets stuck in a loop because your sound card and video are fighting for bus time,by doing the above stops this (and may give a slight improvment to FPS)you can do it on the fly (no need to reboot) just remember that the above tweak also disables EAX and some of the advance sound processing tid bits (all which take up cpu time btw) so if you need that in another game you will need to reset the hardware acceleration back to fullCheersWozza

Thanks for the replies. Will give it a try.:DKev
