Problem with UA-1G - Clipping / Distortion at low levels

I have just bought one of those UA-1G boxes.
I have a pretty decent computer running atm, Quad Core, 4Gb ram, a Soundblaster X-Fi card,
its running Reason, Cubase and Ableton fine, no problems at all. Oh, and Win7 64bit, but also an XP 32bit partition
I have this box set up as per all instructions and suggestions, the little switches on the back are set all down,
44.1khz, record source analogue etc, the Advanced Driver mode is ON, Guitar/Mic Switch set to guitar.
Believe me, if its in the manual, or been suggested on forums, I think I've seen it.
I plug in a guitar, and I've tried with 2 different ones, a single coil Tele, and a humbucker Gibson, and adjust the
volume till the peak light no longer lights, and that is a LOW setting, were talking less than 25% turned up.
Anything I record with is recording very quiet, like if 100 in Cubase is digital hard clipping, Im getting 25-30....
and clipping. Not the hard edge clip you get at 100, but you can definately see the signal is being clipped, and the
sound is 'buzzing'... like a mildly overdriven amp. Nothing in any DAW is approaching a clip signal. I can turn up the
input, and get a louder sound, definately a 100clip, but the buzzing and clipping is following the volume all the way down.
I've tried 2 guitars, and even tried it on an XP32 bit machine to rule out problems with 64bit, all the same result.
For comparison, I recorded some takes through my soundblaster, and get the familar waveforms, albeit very quiet and
the resulting recordings needed normalisation, but there was no compressed look to them, and definately no clipping/buzzing.
I have of course tried every buffer setting from the unplayable largest to the fastest smallest, and it looks like the computer
will handle the fastest setting, I couldnt hear clicks and pops or dropouts.
It also appears to be doing the same monitoring through the headphones, but my headphones are not the best as it is, but
it definately does it while monitoring back through the speakers (basically, Input Monitoring 'On or Auto')
*edit as I remembered something, using it as the main audio device in my machine, playback of anything is fine*

Any suggestions / help here would be greatly appreciated, I'm posting this now because Cakewalks technical support links
are giving me sql database errors or whatnot.

Many thanks for reading

The Heed

Cubase, Wavelab, Reaper, Audacity, Ableton, Reason. Oh... and the bundled Sonar LE
And yup, I've been unplugging it.
I've even tried removing all other USB devices (apart from keyboard and mouse) and trying other slots.
I'm stumped, because as a soundcard, its playing back fairly complex cubase / reason songs at very low latency,
lower than I was expecting (we'll see how the laptop fares with that tho).

I'm beginning to think its a return job, which is a shame

I am going to endeavour to make a few recordings, and post them somewhere along with screenshots of the waveforms,
you'll see and hear the difference, believe me.

Your latency setting may be too low.  Can you set the UA-1G for a 15-30 ms latency to see if the problem follows?

I got excited when I read another post about a guy fixing his similar
problem by updating to v1.0.1 of the drivers, but theres only 1.0.0 for Win7x64.
So I fired up my XP 32 install and tried the 1.0.4 drivers for it, and its the same.

I'm not in front of my system at the moment. will be in 45 minutes... Have you made any adjustments in the windows control panel- ua-1g-asio? I'll assume you have the same issue using Sonar LE...

In Device Manager -> viewing devices by connection, is the usb current taken by the UA-1G within sensible limits?

Yeah, its sitting on a 2 port bus at the moment, one port is empty, and its taking 50%... saying it needs 200ma...
The only other things I have in are keyboard and mouse, both on a different bus, taking 1% each.
So all looks ok. I had tried it in different ports, and removing everything else thinking it might be a power problem

As it happens, I am setting up the laptop right now :)
Just need to get some software on it to test.

After hooking it all up and recording a few minutes, I too have a clipped waveform.  I adjusted the volume/gain on the UA-1G to 5-8 and the guitar to mid volume and got a good waveform. Latency is set to 6ms @44khz.

I can't seem to insert picture...it's a jpg file about 91 kb in size....












 

Just checking the MIC/Guitar switch there was a difference in levels.  The guitar volume is full. The UA-1G was set to 4.
