HS70 Wireless not being recognised as 8 channel

Windows 7

my computer only detects my headphones a 2 channel stereo, not 8 channel.

Despite iCUE saying that surround is on. Surround isn't actually working.

8 channel is neither selectable nor visible to select.

Doing a sound test only simulates 2 speakers, left then right. Also EQ settings don't seem to have much difference.

I have tried:

1. uninstalling iCUE and the hs70 driver in device manager

2. restart

3. reinstall iCUE but then only connect the headphones once icue was working (was not prompted to restart)

4. restart the computer again hoping that the 8 channel not being selectable.

5. uninstall the headphones only and get device manager to check for changes. same thing

6. uninstall iCUE and driver, restart,

7. reinstall ICUE

8. restart

9. plugged in device allowed to install when icue running

10. restarted again

Still no go.

if anyone knows how to fix this it would be greatly appreciated.

Also this is a warranty replacement and my laptop broke recently and required a reformat so no longer have drivers that did actually work (worked prior to replacement and laptop breaking). Already running latest firmware image.

Looks like it's not using correct driver despite my best attempts? Driver info says its using CORSAIR driver though...
