The following article addresses general connection, noise and input/output audio issues. If the issue continues, it's recommended to test on a different computer (if available) to see if the issue is with the Rubix or with the computer.
USB CONNECTION
-
Connect directly to your computer via USB. Do not connect to a USB hub while troubleshooting.
-
Be sure that you are connecting to a USB 2.0 port on your computer; or a USB 3.0 port with backwards compatibility. Check the USB 3.0 specifications of your computer to determine if there is complete support for USB backwards compatibility.
- Is the included USB cable being used? Some commercially available USB cables do not meet the requirements of the USB standard, and this may prevent the Rubix from operating correctly.
DRIVER AND OPERATING SYSTEM
-
Be sure to log on as a user with administrative privileges on your computer.
-
Close/turn off system monitoring/anti-virus software when installing the driver--such as the Norton software you have installed. If system monitoring software such as anti-virus programs are installed on your computer, close them while troubleshooting.
- Did the computer enter standby (suspend) mode, hibernate mode, or sleep mode while the Rubix was connected? Connection issues can occur with an audio interface (such as the Rubix) if a computer falls asleep while connected. If the Rubix does not work correctly after resuming from Sleep mode, exit all applications/software, and then disconnect the USB cable of the Rubix and reconnect it.
To avoid this occurring, it's recommended to not put the computer in sleep mode. - Be sure to not play or record audio for a minute or so after the computer restarts--to allow the system to fully "wake up" and communicate with the Rubix completely.
- Is another program using the Rubix? It is recommended not to use more than one program at a time and exit all programs not in use.
- Was the Rubix connected to the computer while the computer was starting up? With some computers, the Rubix cannot be used if it is connected to the computer while the computer is starting up. In this case, the Rubix will need to be connected after the computer has started up.
- Raise the buffer setting of the audio software (DAW) being used.
(Windows Only) If the problem continues, raise the buffer of the Rubix according to pages 16 and 17 of the manual:
Rubix22 / Rubix24 / Rubix44 Reference Manual -
(Windows Only) Try disconnecting the Rubix from the computer, downloading the driver, running the uninstall program that comes with the driver download, restarting the computer and then installing:
Rubix22 / Rubix24 / Rubix44 Driver for Windows -
Install the latest version of Windows or Mac OS X. Contact Microsoft or Apple for proper update procedures.
-
If you're using Windows, install the latest Service Pack for Windows.
POWER
-
Be sure that the USB port that the Rubix is connected to is supplying 5 volts with at least 500 mA of power.
-
Check Power Management Settings (Windows only):
a. Click on the Windows (or Start) icon on the bottom left of your screen.
b. Select Control Panel. The Control Panel window will appear.

f. Click [OK] to close "System Properties."
ADDITIONAL TROUBLESHOOTING
-
Did you install a device, install software or a plug-in, or make a change in Device Manager just before the issue appeared? If so, it's possible that the change you made caused the connection or noise issue.
Undo the change or uninstall the driver or software (if you can), restart your PC, and then troubleshoot. Depending on the changes you made, some solutions might include:
- Remove or reconfigure the newly installed device.
- Roll back the driver to a version prior to your update.
- Use System Restore to undo recent changes. - Scan for viruses or trojans with any antivirus and/or antimalware software installed.
-
Contact the computer manufacturer and see if the computer is running the latest drivers for the following:
- Internal chipset
- Graphics card
- USB driver/controller
- LAN hardware (wired and wireless)
New versions from the manufacturer may resolve USB issues with the computer being used.
