Windows 7: Audio driver for Sound blaster CT4780 for Windows 7

Audio driver for Sound blaster CT4780 for Windows 7

Hi, I just upgraded my Dell dimension 4300 which was running on Windows XP pro to Windows 7. Everything is working fine except my sound. I cannot see my audio driver through system information or anything. So I had to open my CPU tower and found out that my sound card is Sound blaster live model CT4780. Can anyone please tell me how do I use this card with windows 7. I don't know if it will work with Windows Vista driver and I couldn't find a driver for it. I went to dell's website and that driver didn't work, probably was not compatible with Windows 7. Now in my Device manager setting I see these drivers with question mark
- Ethernet controller
- PCI simple communication controller
- Multimedia audio controller
My bios is A04. Can anyone please help me with that. I searched everywhere possible for a solution, but couldn't find one. I will really appreciate if someone can save me.
Thank you

Welcome to SevenForums!

That's a pretty old SB Live! card... I had one, 8 years ago! Creative's website reports it as:
The product you have selected has been classified as 'End of Service Life'.
Support for such products is limited to online materials, such as Knowledgebase Solutions, drivers, application updates and product documentations available on the Creative Customer Support website.
Customers are also welcome to participate in our discussion forums to obtain further information.

According to both MS and Creative Labs that is not supported under Win7.
Windows Compatibility Center

However, there are a few drivers still posted, one of them may work...

But wait... it's a Dell! Your BIOS A04 is old... you should DL the drivers from Dell according to your Dell Service Tag #.

Windows 7 Home Premium

That card uses the EMU10K1 chip so the KX Drivers will work.

Official kX Project Site -- News

Download the latest full version (even though it says beta). These drivers have been under development for years and are amazingly solid. I'm going to try them this afternoon on an Audigy Platinum and see if I can put the nasty Realtek chipset to rest.

Note: The driver presents every option available for that card... don't be overwhelmed.
One of the features is allowing stereo output out of the second DAC, (black minijack)) which is
actually a more expensive DAC with better s/n specs.

If all else fails give it a try.

Here is the Dell dl page for your Dimension 4300...Drivers & Downloads

But XP is the most recent OS they provide drivers for.

That card is identified as "Sound Blaster Live! Value Dell OEM" as a last resort you might try this package.

problems with sound card CT4780

I'm new to this forum and am glad to see someone else dealing with the same problem I'm having. Unfortunately what worked for BPM150 didn;t work for me. Maybe I downloaded the wrong Kx file? I tried both files listed as 9/8/2009 on the Kx mirror site mentioned in previous post as well as the newest file not listed with 64x or 86x. They resulted in crashing my system with a blue screen etc. I did system restore and tried again to no avail. I also tried the SB P17X Series Support Pack 2.0 (OUTDATED) - Audig... - Creative Labs which didn't work either.

I have a Dell Dimension 8200 32 bit which I bought back in 2001 and has served me well (just added that my BIOS is A03). Just upgraded it to Win 7 Ultimate to better communicate with other machines I am now using also on Win 7. Everything seems to work fine after installing new drivers etc except for:
-Ethernet controller
-Multimedia Audio Controller
-PCI Input Device
Any other ideas or suggestions on getting the sound card to work? I live and work here in Siberia - yes, Siberia - and they have limited resources and parts are hard to find. I just got back here after time in the States and want to get this resolved so my wife and kids can use the system for school etc.

Do I just need to order from the States something like the adapter listed below to avoid the problem?
Turtle Beach Audio Advantage Micro II Virtual 5.1 Surround Channels USB Interface Analog & Digital Audio Adapter

Appreciate any insights or ideas. Will try the Kx drivers again - maybe.

Hope someone can help me fix this!
