Windows 7: C-MEDIA Freezy my PC

Hello guys !
First, sorry for my English...
I'm from Brazil and my English is not god.

Im using Windows 7 RC 64 BITS and i have one soundcard "C-Media CMI8738/C3DX Audio Device PCI" in my computer and every time that i click on the XEAR 3D icon to configure my audio, my computer freezy...he just stop working and i have to restart.

I try to download the last driver from C-MEDIA website but it doesn't work...
Is there's something else i can do?

I have one home theater 5.1 in my PC and i cant use the 5.1 CH because of this...i need to configure with this C MEDIA XEAR 3D

Ill be happy if i get some help

thanks ^^

I have the exactly the same problem. I guess we'll have to wait for new drivers from c-media. If they dont release them when Win 7 finally goes RTM I'm buying new sound card with chip from some othe vendor.

Yes, my friend...
i try to download drivers x64 for this soundcard but it doesnt work...most of this drivers that i get on the internet is for windows vistax64
Unfortunately we'll have to wait...

C-media was always slow with driver updates
I wonder what Microsoft changed that made these Vista-x64 drivers unusable :S

Like you, I've not been able to find any Windows Seven drivers -- but I believe I've found the reason why. I have a card with that chip and read that C-Media will NOT be producing anymore drivers because ASUS has full rights to the chip now. They used it in their Xonar line, but they rewrote the drivers to work with their cards.

Auzentech was a big user of that chip, in their X-Meridian line, and only a few months after they brought out their cards, ASUS bought the chip rights and Auzentech announced they would no longer be making the cards.

I have a Auzentech X-plosion Cinema 7.1 which also has a C-Media chip. The "current" available drivers for it performed badly (BSOD's) until build 7000, when they miraculously started working problem free.

My cards drivers are multi-verse drivers (x32/x64/XP/Vista) which actually use the XP interface instead of the Vista interface on Seven.

Perhaps try installing the Vista drivers with XP compatibility mode. Or even try the XP drivers instead.

What cards are these exactly? on-board/PCI/PCI-e etc? Maybe try to grab the drivers from the manufacturers and not directly from C-Media.

I contacted Auzentech support several months ago and they claimed that C-Media were releasing Seven beta drivers around June. However that was several months ago and a lot of things could have changed....

Just as topic starter I have PCI sound card with 8738 chip. I know this chip is fairly old, but C-media did released drivers for cards based on this chip recently for xp and vista both x32 and x64. This chip has nothing in common with Asus Xonar.
As Ajulian said Win7 x64 driver (for vista x64) installs without any problems, but when you click on a c-media control panel in system tray windows freezes so you are stuck with default setings.

I´m haveing the exact same problem here, if you guys manage to solve this, please post it so all of us will be happy and dancing

Hehe, normaly I'm such a noob, but I guess I fixed it. It's rather easy. It appears that the HT Omega Striker 7.1 (C-Media chipset) works perfectly with Windows 7 RC. So I downloaded the driver (here HT Omega - Driver Downloads) for my Club3D Theatron DD (also C-Media chipset). After that I had the Xear3D working. Than I installed the drivers to my own soundcard. Somehow it didn't update the Xear3D program. After assigning the sounds to digital out in the control panel and in Xear3D, I have full working 5.1 out via toslink. Yay me...

IIII JUUUSSTT LLOOOOVEEE YOOOOU !!!

THANK YOU VERY MUCH !

MY HT IS WORKING 100% NOW
YEAAAH !

120 rms of power YEAH !
