Hello,

It sounds like you may have to optimize your computer a little. Check out these tips:

There are several reasons why you may be getting pops, clicks, and hum with our USB devices. Here are some things you should check first.

1. Fill out your support profile at http://line6.com/account/supportprofile/

2. Ensure that you have tested all cables to make sure that they are not defective (USB, audio, etc.)

3. Ensure that you have all cables connections set up properly

4. Adjust the Buffer Slider in the Line 6 Audio MIDI Control Panel. (Windows Users: Start/All Programs/Line6/Tools/Audio-MIDI Devices; Mac Users: System Preferences/Other/Audio-MIDI Devices)

5. Adjust Sample Rates and Bit Depths in the Line 6 Audio MIDI Control Panel and ensure that the Sample Rates and Bit Depth settings in the Line 6 Audio MIDI Control Panel also match the project settings in your DAW/recording application

6. Ensure that you have the Line 6 device set up in your operating system as the main input/output device (sound card); disable internal sound card in your operating system’s Device Manager control panel

7. Ensure that your Line 6 USB Device is not connected to a powered USB hub; direct USB ports are required and please try ALL available direct USB ports during the troubleshooting process

8. Remove all non-essential USB peripherals from the computer (not the mouse or keyboard)

9. Disable any wireless cards on computer in Device Manager

10. Set Power Schemes on computer in Control Panel (PC Only) to Always On

11. There are also several other tips and optimizations you can make on your PC. Please refer to the following document for more information:

Hi,

This is a known issue we are working on with the HP DV series w/ AMD & Vista. Beyond the optimizations mentioned above, you can try getting the AMD USB Filter Driver from HP. Also, while we do not support the use of USB hubs, a user in another thread resolved this same issue: http://line6.com/community/message/51817#51817. So you may try these at your own risk, but beyond that we are currently working on a resolution.

Thanks

Hi, tried the "powered USB hub" solution and nothing... The UX2 wouldn't even work. I'va had moderate success using TWO usb devices (my UX1 and an EDIROL Midi), but still some crackling comes up.

Come on Line6!!!! Your reputation is on the line!

Hi,

I got the same issue and fixed it (at least for the time being ) by disabling my Wireless interface (and setting the power mode to "Max performance").

Laptop is an Asus X52J, Windows 7 64bits.

I had the same issue and I found that it went away by 1) plugging it into a 2.0 usb port then in podfarm I went preferences>hardware>tonedirect settings and changed the bit rate from 16 to 32bit and buffer size to extra large. Give it a shot!
