Already done that, installed from the CD, installed from the site...didn't work.
Plug out the power then then press power 5 times.
After that, plug in power and test the jack(s).
For some people this worked, somehow. If this doesn't work, try this:
Go to Device manager --> Expand "Sound, video and game controllers" --> Right click on the right audio device --> Uninstall --> reboot PC --> Test
