HD audio !!
front audio speaker works when i remove my rear connector for speaker ,both don't work simultaneously !!
Go to your Control Panel, search for Realtek HD Audio Manager, go to Advanced settings, check front and rear output devices to play simultaneously. I think that should solve the problem.
In case the option is not in the Control panel, install the latest drivers and try.
BTW, nice cable mgmt. Both you and Gamma deserves kudos. Its the best cabinet at its price range. And interior is black too
Something even pricier models of Lian-Li don't have.
