I'm experiencing an intermittent loss of FSX audio at irregular intervals of about every one or two minutes. While each audio loss is only of one or two second duration, it is an annoyance to say the least. So far I have: 1.) Rebuilt FSX.cfg;2.) Ran FSX CD Repair function;3.) Ran FSX CD Acceleration Expansion Pack Repair function.Negative success.System:Vista-64i7 9406 M RAMNvidia GTX 285.No problems with FS2004. Any and all recommendations are appreciated.

have you tried turning down the FS sound quality settings?do you have an on-MOBO sound 'card', or a sound card?--

According to NickN the buffer pools tweak may reduce the sound problem(s). Here is pic with texture (hope you can read it). If not, hold Left Ctrl key and roll your mouse wheel to magnify (zoom in/out).Chuck BNapamule

Thanks, this could be challenging for my pea-brain. Where is the bufferpool setting found?

Add this to your fsx.cfg file:

[bUFFERPOOLS]Poolsize=490000000

Add this to your fsx.cfg file:

[bUFFERPOOLS]Poolsize=490000000

Got it, thanks.

That's interesting that you mention that because my old 8800 Ultra died December 24 (what a holiday present!), I swapped it temporarily with a borrowed 9600GT and just by doing that got me into horrible sound issues in DX9 mode (no problems with DX10). I have since received my replacement card, an ATI 5870, the sound is now back to normal. The odd thing is that I didn't change anything related to FSX. I didn't even change the driver for the 8800 to the 9600GT because it's the same. I did, of course, change drivers for the ATI card.The only difference as far as I can tell is the memory on the video card and how this relates to bus latency that causes sound crackling/popping issues in FSX. The 8800 Ultra had 768Mb, the 9600GT 512Mb, and the 5870 1Gb.I played with the bufferpools settings and sound quality values without any luck, so there was something about my hardware combination that caused this. The only thing I had to do was to turn tree autogen way down (as is suggested with the max cell value), that helped, but my visuals suffered. I use digital optical audio so the sound processing is done off-PC (the optical out is off a Realtek 7.1 HD chip so I have technically an on-board sound although it's off the PCI bus according to my motherboard diagram). I don't think it's a sound card issue at all given that changing video cards while keeping the CFG file the same (except for the video card entry of course), fixed the issue by itself. The difference was more than 512Mb of memory.I believe the issue with sound in FSX has a lot to do with the amount of data the simulator pumps between the disk and the video card (textures?), and less of that occurs when you have a video card with more than 512Mb of memory. That is purely speculation on my part of course.Cheers,

Ziporama,Now post what OS you have. If it's XP or Win 7, 32 bit or 64 bit. Then you might get an 'educated guess' answer. Otherwise you leave us in limbo. Because, depending on OS, you might not need ANY tweaking done to FSX cfg, irregardles of video card memory. What you have in 'OS' is what you get (or don't get) in 'FSX'. They work together.Reading 1st paragraph I thought 'drivers'. Kept reading and thought 'what OS?'. Kept reading and thought 'what problem?'. So all I need to know now is what OS or I may not ever get to 'what problem?'. I have sound crackling in FSX w/ XP SP3 (always have had, even w/ XP SP2). Same ATI AGP 512 mb video card too.Chuck BNapamule

LOL.Yes, Windows 7 x64... Note: if this thread is turning to hardware, please post in the hardware forum. I was just relating my experience on the issue.Cheers,
