Topic: [IMPL] Open source (BSD) C-Media 8738/8768 WDM drivers

Just discovered this website:

http://cmediadrivers.googlepages.com/

This project aims at developing drivers for C-Media 8738 / 8768 based soundcards, focusing on providing a bloat-free, stable and reliable alternative to the official drivers in order to squeeze the most out of the hardware.

A PCI soundcard with a C-Media chip and Windows 2000/XP/Vista are required to run this driver. Due to arbitrary driver signing restrictions, the 64 bit version of Windows Vista is currently not supported although there's a workaround for installing and running the driver. However, they're fully compatible with the 64 bit version of XP and the 32 bit versions of every aforementioned OS.

I hope someone is interested in collaborating with the author to improve them...
I also hope it could be the 1st step to have more open source drivers here...
Last but not least check out my 3ad @ ROS forum

Hope that helps !

For those who are interested in, here's what the Echo Digital Audio Corporation' Software Developer Page claims:

Interested in writing your own driver for Echo’s hardware? Then you need the generic driver code. This is the cross-platform C++ library used for our Windows and Mac PCI and Cardbus drivers.

I did integrate the driver in the test pack and did the necessary changes.

Test it and let me know, great suggestion btw thx again.

Re: [IMPL] Open source (BSD) C-Media 8738/8768 WDM drivers

After some licensing discussion, drivers now included in ReactOS !!!  lol

0.3.3 changelog -Audio Stack
* Port Class (PORTCLS): Minor adjustments so that this now compiles without error. A lot of work still needed (Andrew Greenwood)
*  Kernel Streaming (KS): Again, minor adjustments to KS itself and its headers (Andrew Greenwood)
* Drivers: NT4 style drivers now deprecated, WDM-style drivers to be used instead (Andrew Greenwood)
Magnus Olsen has also imported some open-source C-Media WDM audio drivers (these do not compile for us yet)
* Legacy support: Removed WDMAUD.DRV (pending a rewrite) and also begun clean rewrite of MMDRV.DLL (Andrew Greenwood)

Maybe my "fault" ?  cool
