Windows 7: Computer not recognizing speakers after installing USB3.0 internal hub

Computer not recognizing speakers after installing new hardware

Hi guys,

I recently installed an I/O Crest PCI-Express USB 3.0 Controller Card and after installing it and its drivers my computer wasn't recognizing my speakers. I tried switching to different speakers and headphones in both the front and rear ports but nothing worked.

Next I went through the forums and followed the instructions suggested:
Update drivers (they were already up to date)
Uninstall then reinstall drivers
Disable then re-enable device
Turn off computer, unplug it then wait for 5 minutes then reboot
Uninstall the USB hub

None of those worked so I thought that that maybe my sound card (it was integrated with my motherboard) had just bit the dust so I went and bought an ASUS Xonar DG Audio Device, installed it and the drivers. Now my computer has recognized my speakers, but sound isn't coming out of them. They are currently set to the default device and when I open the playback devices window I can see the sound bar next to my speakers moving when sound should be playing but I don't hear anything. My sound isn't muted and it is set to 100% output.

Hopefully you guys can help me out.

Problem resolved itself after downloading Xonar DG Audio Center and adjusting settings.
