I have the same scpecs as u but SB X-Fi Xtreme music and never had any problems with the game xept computer gets overheated when not using a regular old fashion table fan to cool it down with... but still can play 20x20 with all but shadows and AA on and 40x40 4 players on low without probs.

What's the latest in fixing Vista, DX10 and integrated sound card compatibility... is the sound issue being adressed or should I start auctioning my game on ebay?

Auction your OS on ebay i would suggest.

this is getting silly now. nearly a month and no fix v_v

I'm having the exact same problem you are. Unplayable stuttering and screenfreezes, with that repeating sound. I've tried nosound, done all the dual core fixes, win2k compatability, dxdiag sound adjustments, everything I could possibly think of, and nothing has changed. I'm getting really tired of this, and hoping this game isn't going to be another "too little too late" scenario with the patching. The game being unplayable for a lot of people after 3 weeks is pretty unacceptable.

I'm running:
Athlon X2 3600+
2 GB Corsair DDR667
BIOSTAR TFORCE 550 Nvidia 550 chipset motherboard, onboard Realtek HD Audio
Sapphire X1950PRO 256 mb

Same here initially when I tried it on my freshly formatted machine. I tried it on my development machine(making sure to set the DX debug options to release mode) and then it ran great. They are the exact same machines, with the same hardware, same drivers and everything... Just one of them has dev kit(DX SDK, Platform SDK, VS2005 etc...) and the other is a fresh install of winXP SP2 with updates for all drivers and apps.

As a developer, I suppose I could run this down to see what the difference between the two machines are, but hey, at least I got it running!

I MYSELF HAVE HAD THIS PROBLEM AND WAS ABOUT READY TO CURSE THE GODS THAT MADE THIS PROGRAM... BUT AFTER LISTENING TO THE ADVISE I ALSO FOUND THE LATEST DRIVERS TO MY ONBOARD SOUND TO THE MOTHERBOARD THAT I HAVE (ASUS - P4S800D-X) AND INSTALLED THEM... WITH THAT MY SOUND WORKS LIKE IT SHOULD... ALTHROUGH I STILL HAVE A QUESTION THAT COULD NOT THE PEOPLE WHO MADE THE PROGRAM NOT FIX THIS PROBLEM WITH A QUICK PATCH INSTEAD OF US TRYING TO FIGURE IT OUT....

What problem did you have, stuttering, performance, lack of sound effects, lack of voice or problem with 3d 5.1 sound? Please test and report back, i'm sure GPG devs are scouring this thread.

This seems to be an issue with GPGs desition on using Microsofts XACT sound system. This sound engine is software only so it will sound good on your on-board HD chip but it uses CPU for mixing and effects and your 3D audio chip will be fairly idle.

The XACT sound system was originally deveoped for Xbox development but has eventually been included in DirectX and lately is part of Microsofts major monopoly tool XNA. XNA is a semi cross-platform framework that makes it easier for game developers to make games for both XBox 360 and Vista at the same time.

Maybe that why so many problems?


I have to set audio to stereo speakers or else I only get audio in rear speakers.
It happens in both Vista and XP SP2.

This isn't a driver problem, it's a problem with Supreme Commander.

I don't know if any one else has had this problem, but my sound issues stem from an installation problem. I can play the game fine, it’s just that there’s no sound. I get an error message when installing stating there was a C + + runtime error. I’ve re-installed the game more times that I care to remember and from different copies. I’m no computer expert so I dunno if this is something to do with my hardware or some kid of problem with my OS. Any help would be greatly appreciated.

Sorry, I should've gone into more detail about the problems I was noticing.

Both machines are the exact same machines, but one was freshly formatted and has a fresh install of everything, whereas the other machine is a developer box and has a bunch of developer tools installed on it.

Machine #1 - Clean machine

I hear looping sounds. Sounds like a buffer is not getting cleared correctly and the only way to solve it is to zoom in/out really far to force a rank buffer to kick it out. Since I zoom in and out fairly frequently, this isn't a major problem, but something that should be looked into.

Machine #2 - Dev machine

Sounds come through fine, and I don't hear the looping sounds, but I do get the severe performance issues. I haven't cracked open my Intel vTune(profiler) to see where the performance is, but maybe that'll help?

Both machines are:
3.8 gHz 2 gig RAM
NVIDIA 7950 GX2
Creative X-Fi

I have an X-FI Fatality card and all that comes out of my rear surroundsound speakers is music. My front speakers have sound effects come out of them but it is reverse. If I am ahead of a unit making noise the sound is coming out of the front speakers instead of the rear, if I am behind a unit when the sound should be coming out of the front speakers... I hear nothing. As for why supcom doesn't have in game options for hardware soundcards and options assosciated with them (aka what speaker setup you have/hardware sound/etc), is beyond me, every other game has them. Hopefully this will be addressed in the next patch. My OS is Windows XP 64 bit.

Negative. I played with speakers, handcuffs and 5.1 surround. All gets very poor performance.

lol, even so desktop speakers only utilize 2 speakers.... which sucks if you have a 5.1/7.1 setup

I installed the last drivers for my X-Fi XtremeMusic and applied the 1.0.3220 patch.
I started a 1vs1, small map, 500 units limit, skirmish with all video setting to LOW and MEDIUM FIDELITY (to have textured terrain).
The frame rate was acceptable untill base attacks started. With all the units, explosions and bullets flying the game was so slow to be uncontrollable.

STEAM statistics says that my hardware still above average , infact I can run all recent games with excellent FPS at medium detail level (es: F.E.A.R. or Medieval2 TW).

The question that trobles my mind is: IS IT NORMAL TO PUBLISH A GAME THAT CAN BE PLAYED BY THE 5-10% OF THE GAMERS IN THE WORLD?

Strange marketing policy.

no it aint normal they cant get the sound even right

I was very surprised to see the STEAM survey said less than 10% of the users have Creative cards and most users (about 26%) use Realtek AC97 audio.

The goal of marketing is to encourage consumers to buy your product, not to ensure they can actually use it. Considering the number of people who have purchased Supreme Commander, I'd say the marketing department deserves a bonus. Of course, the game development department needs to be sacked and a competent team brought in to clean up the mess they left and give consumers something resembling the product they thought they were purchasing.

What X-Fi version?
Stereo or 5.1 audio mode?
How does the game sound in 5.1 audio mode, almost no audio from front speakers?
Console Launcher linked to Windows Audio Control Panel?

I have an X-Fi music card (through Dell) on a Vista, dual core machine. Natively, the audio actually works, though just stereo. I have a 7.1 speaker setup and would lke to use it, but I understand the Xact msft thing. So, I tried puting ALchemy on my system. I copied the 2 sound files into the bin directory of supcom. In this mode, I only get rear sound effects, the front speakers do nothing.

Both modes though, I am able to make out what is happening (no skipping, repeating, etc). So for now, I just play it in stereo... though, under sound options, I see no option for different audio modes (stereo, surround, emulated 3d), I only see volume levels for sound effects and music.

Add another person to the list of those that had a large performance boost going from 5.1 to desktop stereo speakers. A -171 perftest jumped to a 8071 perftest on high settings with low shadows at 1680x1050 resolution. I am running an Audigy 2 ZS, Athlon64 3000+ (2GHz, single core), 1GB of DDR ram (400 MHz), and an x850 pro on windows XP.

Setting sound hardware acceleration to basic gave a small performance hit, setting acceleration off gave me a -127914 perftest (possibly the lowest score ever achieved!). My realtek onboard audio also gives a small performance hit compared to my audigy with equal settings (stereo speakers, etc.).

The important thing that I can add to this thread is a recommendation to enable CMSS 3D "stereo surround" if switching to stereo speakers. This setting is found under the EAX Console (I assume all recent Creative cards will have that available). CMSS 3D plays the stereo sound over all speakers and actually sounds much better than the SC surround implementation in my case (and also makes music sound great, by the way). With normal surround, I have the already mentioned issues with sound positioning (combat sounds play over the rear speakers unless I zoom in), but CMSS plays everything evenly. Additionally, perftests have shown CMSS 3D to have no noticeable performance impact on my system.

So, in summary, switching from 5.1 to desktop stereo speakers under the windows control panel and enabling CMSS 3D under the Creative EAX Console provides me with drastically improved performance and much better quality sound.

Hello i hope some one can help.

I have a system that runs Vista 64, 2gb of Ram, 8800 GTX card, E6600 cpu, an intel D975XBX2 mobo with sigmatel HD audio codec driver version 6.10.5290.00 running.

The problem i have is that i can't get the game to run with sound. Every thing is upto date, even my mobo bios, i ve tried the set the system to normal stereo sound etc but to no effect i just can't get sound.

Any ideas please to help me get this thing running, cheers.

In the mean time i will just wait for tech support UK to sort this out !!

I am right there with you. I have a vista 64 system with 4 gigs of ram, pentium d 960, and an intel board with the sigmatel audio chipset.

I have absolutley no sound in sc either. No one from tech has acknowledged whether it's a driver issue or a game issue.

My guess is game because all my other games run just fine that I play.

Cheers..

Yeah I have the same issue, all my other games and media work just fine but this game just doesn't want to play the sound. When and if i get a reply from tech support i shall let you know Thehunted.

At the moment its in the to be played pile along with Sid Meier's railroads !
