Simple hack to add 10-band Equalizer and surround control to C-Media 8739 audio
Posted: Thu May 26, 2005 9:07 pm
My MediaPC has an onboard C-Media 8739 audio chipset. This is a great chipset, but it lacks any kind of equalizer controls (not even a treble and bass control in the audio mixer) HOWEVER the ability is there with the right software.
Did some Googling and found this interesting hack for the CMedia 9739 drivers that allow them to work with any C-Media 8739 chipset sound hardware, and it works well. It adds an SB Live-type environmental control panel with surrond settings, environmental audio controls, and a 10 band equalizer.
Only thing I did different than the following instructions was that AFTER I installed the driver using the Device Manager wizard, as recommended, I rebooted and then installed the driver and apps using the SETUP.EXE file that comes with the drivers (just installing the driver alone doesn't give you the EQ and environmental audio controls). After rebooting again, you have a taskbar icon that opens the audio control panel.
The EQ has a full 10 band equalizer and a dozen presets, plus you can add your own presets.

Instructions:
Download the new CMEDIA 9739 drivers from the following link :
http://www.cmedia.com.tw/download/e_UDA039.htm
Download JUST the driver - no need for the Audio Rack crap.
Then modify the CMVIA.INF file , adding the following lines under the [C-media] paragraph :
%CMI8738.DeviceDesc%=AC97, PCI\VEN_13F6&DEV_0111&SUBSYS_011113F6
%CMI8738.DeviceDesc%=AC97, PCI\VEN_13F6&DEV_0111&SUBSYS_011013F6
After that , uninstall the older cmedia drivers and install these with the "device manager" way ...
After the installation , reboot your computer and enjoy the new drivers with built in equalizer with alot sound themes to choose from , new 5.1 virtual mode and God knows what else ...
I have tested them and they work absolutely fine on my rig.
NOTE: I have tested the mod to the CMVIA.INF file only , because i have a motherboard with a VIA chipset. The drivers have other files for the other chipsets , but i haven't tested the mod on them. So BE CAREFUL if you risk the mod to these files...
