Also your system appears to be having trouble which may be attributed to SMI routines, CPU bugs or unexplainable CPU stalls. Also one or more ISR routines belonging to a driver running in your system appear to be executing for too long. One or more DPC routines belonging to a driver running in your system appear to be executing for too long. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. Your system appears to be having trouble handling real-time audio and other tasks. All the values are far beyond the 4000 µs!! according to that I have serious problems. Please, tell me about any procedure, application or anything to solve the problem, since I've ran out of ideas. I've even formatted the computer and now I'm running only with Win, the motherboard drivers, the graphics accelerator drivers and the most recent RME drivers/software.

It is not a 'last generation' system, but it exceeds the minimum requirements to use this interface. no problems with video, memory, processing, etc. Apart from the problem with the FF400, the computer runs well. The user guide says there is no problem with this cards and in fact is the recommended solution in this case. The motherboard had no FireWire port, so I installed a PCI-card. As I've said the system runs Win7圆4 and other main features of the computer are: IntelCore2 Quad / 8GB DDR3 RAM / Gigabyte Geforce GT440 (1GB DDR3). I think the problem could be the computer. Using headphones the problem keeps going on, but using the device as a stand-alone there is no problem, so I think we can discard the own unit and the monitor system. I've followed every step in the user guide in order to avoid this problem: I've increased the buffer size from the default option to each one of the values above since I've arrived to the maximum allowed (1024 samples) but the crackling goes on, making difficult to hear music (or even the own Windows sounds) and impossible to work with daws or similar programs. Hi guys, I need some help from you, since I'm having problems avoiding crackles in mi FF400.
