Edirol UA-1EX - hearing noise on audio playback

I pretend to use the UA-1EX as a USB audio interface between a "Sony VAIO FW-21M" laptop (with Windows Vista 32 bit OS) and a pair of powered monitors "KRK RP6".

I installed the driver and the audio device works fine if the laptop is on battery mode, as soon as I connect the laptop's AC power to a socket (all the sockets were tested and they have electrical ground) I started to hear a loud noise/distortion (like radio static) through the monitors in the audio playback.

I checked all the items from troubleshooting in UA-1EX owner's manual and I can't solve the problem, there's no mic connected, or a microwave or a TV nearby. In the room is just the laptop, the UA-1EX and the monitors.

To test the UA-1EX, I connect it to a "Macbook" and it works fine with clean sound (battery mode or plugged into a socket).

To test my "Sony VAIO", I connect it to a "Native Instruments Audio Kontrol 1" audio interface and it works fine with clean sound (battery mode or plugged into a socket).

So, apparently all the devices are OK, but the truth is when I try to plug my "VAIO" laptop's AC adapter to a socket, the UA-1EX can't filter the static (or whatever is that noise that starts) and passes all that noise to the monitors make it impossible to have a clean sound, consequently it's impossible to produce any kind of work, and the laptop is connected to electrical sockets 99% of the time.

Notes:
_As I said before the UA-1EX worked fine with a "Macbook". Both "Macs" and "VAIOs" have AC adapters, but while the "Macbook's" AC adapter transforms 220V (Europe) into 16.5V, the "VAIO's" AC adapter transforms 220V (Europe) into 19.5V, I don't know if it could be important.

_The only thing I couldn't check in the UA-1EX owner's manual troubleshooting was the item "Advance Power Management Support" and "Don't Poll Power Supply Status", can't find this in Windows Vista Device Manager, only found the battery power management but it's useless.

I really appreciate that you could help me to solve this.

The UA-1EX can supply phantom power to condenser mics so the issue with the noice is a ground loop problem between the UA-1EX and your other devices (laptop/amps in the powered speekers.) I had the same problem so I found a Direct Injection box (D.I.) that allowed me to convert an stereo RCA Signal to two balanced XLR signals or vice versa. Whirlwind is the brand of mine. There should be two grouding switches on the DI that will allow you to ground the UA-1EX and get rid of the noice. Hope this helps.

No solution, but I had the same issue with my old laptop, I tried everything, the only thing that worked, was to use a voltage generator, set it to 19.5 V (this was what my laptop was converting to) and getting a laptop power plug and creating a connection. Because the power pack is a SMPS, it was very noisy and this noise would be transferred to the recording.

Question of my own, where did you find drivers for Windows Vista 32 bit? I can only get my UA-1EX to run as speakers, not a recording device!!! HELP!

    Worked it out, Vista was setting it as a speaker device, once I changed that setting, it now operates as a recording device

When i playback in WDM mode, i hear ckrackles and pops, when i playback in the other mode the ckrackles and pops are gon, but the input and output goes to none. how do i get rid of the ckrackles and pops...


1. check your user manual for clicks/pops.
this could be due to devices connected to the Edirol UA-25 or a television or microwave.
2. this also could be due to the setting in Windows Energy saving settings.
that is the Windows "sleep mode" and power saving mode.
3. this could also be due to the USB cable.
4. you may need an external filter device for the process you are using.
5. read your manual on Troubleshooting Noise ( clicks and pops).

It sounds like this may be a driver related issue. Can you please try downloading the latest version of the driver for your operating system from the link below and installing that to see if it resolves the problem.

UA101 and Blue Screen of Death


try this to make sure that the driver was installed correctly.:

Note: Do not use the “Add New Hardware” Wizard in the control panel. Follow the steps below to install your driver correctly.

1. Plug in the USB cable and power on the device – the New Hardware Wizard will start up (wait for it to start).

2. If Windows asks to connect to Windows Update, click on “No, not this time” and click on “Next.”

3. Select “Install from a list or specified location” and click “Next.”

4. Select “Include this location in the search” and Browse to the folder containing your driver (either on your CD or the folder you downloaded). Click “Next.”

5. Click “Continue Anyway” when the Windows Logo testing screen appears.

6. Click “Finish” when the Completing the Found New Hardware Wizard screen appears.

At this point, you may need to reboot your computer. After restarting, you should check to make sure the driver was successfully installed. Go to Control Panel / Sounds and Audio Devices and make sure your device is listed under “Sound Playback” and “Sound Recording” for audio devices and “”MIDI Music Playback” for MIDI devices. You should also check in the Device Manager to make sure your MIDI or Audio device is listed under “Sound, video and game controllers” with no problems (such as the yellow exclamation point).

If everything is successful to this point, Windows has installed the device correctly and is making it available to any software you need to run. If you can not see your device in your software, you should first try re-profiling the device (different software programs do this differently). If this does not work, you may need to uninstall and reinstall the software. If you still do not see your device, you may need to contact your software vendor for more help.

- Mac OS X -
1. Make sure the Roland/Edirol device and any non-essential USB devices are disconnected.

2. Run the *.pkg installer from the CD-ROM or downloaded driver and follow the onscreen installation instructions. When finished, reboot fully.

3. Plug in the Roland/Edirol device. Ports should now be available in software (you can verify driver availability in Applications > Utilities > Audio/MIDI Setup > MIDI Devices).

- Mac OS 9.X -
Users must first decide if they want to run OMS or FreeMIDI, which can be downloaded from the World Wide Web. OMS is recommended. See the OMS or FreeMIDI documentation for installation and activation details.

Double-click the Edirol installer and follow the onscreen installation instructions.

Note: If you continue to have problems, you may wish to consider upgrading to OS X, as its Core Audio and Core MIDI features make this operating system an excellent base for music applications.

Pop/click/dropout is often a buffer size problem. Be sure to check your Buffer Size setting. You'll find it in the Edirol Icon in System Preferences or in the Control Panel of a Windows machine. Increase your buffer size until the problem goes away.

There are also several settings you will want to make in order for audio applications on a Windows XP computer run optimally.

One of the more detailed websites to walk through these settings is MusicXP.net.

Mic problems: playback works great through interface, microphone isn't being detected


Check in contraol Panel under sounds and audio devices that you are using the Edirol and not an on board sound. It sounds like although the cards installed its not selected as the audio device to record from. You will also have to tel Adobce audition to select the Edirol as you audio card of choice as it to can be changed to select input from other sound devices.
