Here is an official driver for the CMEDIA 6206. It is packaged for windows 10 and includes an example INI file in the ZIP (\WIN10\SoftwareDriver\INI\cm106.ini) which disables all the unneeded features and enables only 6 and 8 channel modes.
https://app.box.com/s/kif4vmtg6sahqeml80ylbp39nmw7j8l9After install you still have to open the windows sound control panel and set the card to NOT default and 7.1 mode. I have tested this driver with the EZAudDac.dll and it works fineI have also tested with 6 channel laserboy waves, Spaghetti and LFI player.
The INI file should be saved to C:\Windows\cm106.ini if its not automagically installed.
Just unzip the above file, run the setup, open windows sound control panel set the driver to 7.1 mode and NOT default, reboot. if the CMEDIA control panel still has extra features (like karaoke mode effects) simply overwrite C:\Windows\cm106.ini with the one included in the zip, uninstall the sound card in the device manager and reboot. The sound card will be reinstalled with the new INI on reboot.
