At some point FS9.1 began complaining tha tFSSound.dll might not be compatible and offered the choice of loading or not. Loading it causes no problem. I've seen this discussed on other forums, where the consesnsus is that it isn't a real problem, but no one knows what the cause is.
I was wondering if anyone here knows the cause and if there is a solution. It is a nuisance if I start FS and am distracted. Five minutes later its still sitting at that damned dialogue box witing for me to click OK.
I suppose some dufus addon added/modified/replaced/stomped on the file, but don't know which one is the culprit.
When you load an aircraft you might be installing (overwriting) an older version of it than you need for other aircraft.
This happens often with self installing aircraft (exe.).
That's my take on that nuisance message.
Crash, have you tried this
Find fs9.cfg & open it in Notepad. Add this entry (it doesn't really matter where providing it's a new entry) & exit Notepad saving changes.
I think the cause comes down to the arthur using a 2002 that has been upgraded for us with FS9 but uses 2002 gauges and sounds. Others will correct me if im wrong (must fo the time)
right slightly concerned that i couldnt find my fs9.cfg file.....that is one of the config ones isnt it?!?
AJWatson try this
1} Double click My Computer
2} Double click Hard Drive
3} Double Click Documents & Settings
4} Double Click Your User Name
5} At this stage you will need to acces the hidden folders. Go to Tools at the top of the task bar, then Folder options, click on view, in the advance section you should see a tick box called show hidden files & folders tick this and click apply & OK. All hidden folders will come to light.
6} Double click on Application Data
7} Double click Microsoft
8} Double click FS9
9} The FS9 CFG file should be the third one down on the left (well it is on mine)
Open it up with wordpad on copy and paste the added section in my previous versoin.
Let us know how you got on.
Okay. Been there, done that, darn shame it didn't work. 😞
sorry guys i think i have posted that reply in the wrong topic....... sorry
I get the same bloody thing, had it for months. Don't know what to do but ignore it.
Here is my fix. I went into ...\program files\...FS9\modules and renamed it to fssound.dll.bak. FS started up with no complaint.
If I find a plane that has no sound now, I will know the culprit. If it can't be aliased to an FS9 sound file, I'll get rid of it.
This is the info I have on the dll.
File Version: 184.108.40.206

If I find out what package dropped this on my doorstep, I will let you know.
Final fix. Went to and downloaded version 220.127.116.11 beta2 and got no complaint from FS. FS does not like 18.104.22.168 or prior. I don't like beta software, but apparently some gauge designers are using it and FS doesn't complain, so I'll give it a try unless green slime starts coming out of my speakers.
As the last update was over a year ago, I won't hold my breath till 1.6.x final comes out.
Top man it got rid of .dll box at start up but have lost a few sounds for a/c. Only tried a couple but I'm sure I had sounds for them before.
