I recently bought the UR12 interface. I’m experiencing the same audio dropouts that many users have described on this thread. I’ve been reading through this thread carefully as much as I could. Despite not reading everything, I believe I managed to get some good idea of what’s going on and see most relevant info and success stories.
As far as audio dropouts go, I can tell that there are at least TWO different types of dropouts described.
At this point I believe the two are unrelated and caused by different problems.
1 – audio dropouts – occurring specifically during hi-performance ASIO playbacks. (Short interruptions lasting milliseconds, ASIO driver specific cra*p , clicks and pops and spikes)
2 – big A** CUTOUTS OR USB SIGNAL INTERRUPTIONS – occurring during any type of playback (windows or DAW) LASTING MUCH LONGER.
I’m in the second category.
This is the description of the problem briefly:
The audio cuts out for periods up to 1 seconds. The interruptions are never short (IE. milliseconds).
During these cut-outs, the UR12 USB light FLASHES as if it lost the USB connection.
The cut-outs occur randomly but ALSO on any type of screen activity, IE: scrolling the audio timeline, zooming audio timeline, moving a window, dragging/selecting audio or even moving the mouse cursor. The USB light would start flashing and audio would disappear for up to (or around) a second.
Every time when pressing start on the DAW transport, DAW meters start straight away, the USB light on UR12 flashes and then sound from UR12 comes in roughly a second later. The DAW/driver appears to do their job while UR12 looses connection briefly.
This scenario occurs also when using WINAMP or any other music player or DAW (I use Mixcraft and Reaper and tested on the Cubase AI that came with the interface) on any driver scenario – ASIO, ASIO4ALL, Core Audio, Wave out etc.
All of the above happen regardless of CPU load, file complexity, VST instruments used or indeed DAW 64 or 32bit or Windows sound or whether there’s nothing else plugged in the USB ports and all possible hardware being disabled.
System:
Dell Inspiron 9400
Core2 DUO 2Ghz
3Gb Ram
Ati Radeon mobile X1400
UR12 – driver version 1.9.10 latest firmware 1.07 (haven’t tried older driver versions).
Windows7 64
Mixcraft 32bit, Reaper.
What I did trying to address the problem:
- Updated all drivers (Chipset, Network etc) except for the Radeon (no new drives avail. due to discontinued support from Dell/ATI/AMD for Inspiron 9400/ Ati Radeon mobile X1400), running anything except Windows XP.
- Disabled everything (including WiFi).
- Set Windows to work in high performance mode, favour background processes, Processor min/max 100%, Made sure core parking is disabled using the Utility, - I even temporarily disabled Speed step in the system BIOS making the system run to 1Ghz.
- Tried lots of different USB cables (different lengths and ferrite blob too).
- Tested using Latency Monitor – no lazy drivers – the only warning is in regard to CPU throttling (although CPUz reports system running always 2ghz flat).
NO LUCK WITH ANY OF THE ABOVE
Other interfaces I used on this laptop succesfully: RME Fireface (old one), MOTU Traveller MK1 (through the built in firewire port and pci express firewire card) – worked perfectly well.
The funny thing is that Mixcraft works perfectly well (with some latency) with the inbuilt soundcard in “Core Audio (Windows)” or with the Generic low latency Asio driver mode.
For now UR12 is unusable for any kind of playback let alone music making. Shame because it’s got overzealous built quality and is as heavy as the laptop!
I suspect that this is an USB Power problem or some serious hardware conflict.
I’m yet to try powering the UR12 from an independent 2A source using the mini USB connector (I tried briefly using a phone charger, problem was still the same) or to buy a PCi Express USB card AND a 2A power supply to power the ports.
I have a Desktop Workstation which is in storage at the moment as I moved house. I will try the UR12 on that at some point. However, if it works well there won’t mean much to me because I use the Traveler on that setup and I intended the UR12 for the Laptop\Mobile setup.
