1 Focusrite Saffire Pro 40 audio dropout after few seconds
Hello,

I just got my Focusrite today in order to track some drums. The problem is, that using the ASIO driver, audio drops out after about 5 seconds.

I can sort of reset the driver by changing the sample rate in the mix app to 48Khz and then start playback again, to no avail.

I also have problems with my Presonus FS Mobile, mainly some stuttering - maybe my TI firewire chip is going bad? I've tried all drivers from TI to legacy, tried different versions of Focusrite drivers, etc. Nothing helps. I only get a moment of audio from my Genelec monitors.

Everything seems proper - sync is OK, lights are green.

Running Windows 7 on an Abit IP35 motherboard.

CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. Also one or more ISR routines that belong to a driver running in your system appear to be executing for too long. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
LatencyMon has been analyzing your system for 0:04:43 (h:mm:ss) on all processors.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

Highest measured interrupt to process latency (µs): 7603,808697
Average measured interrupt to process latency (µs): 4,454490

Highest measured interrupt to DPC latency (µs): 7587,766186
Average measured interrupt to DPC latency (µs): 1,256055

REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.

NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.

Process with highest pagefault count: svchost.exe

Total number of hard pagefaults 2119
Hard pagefault count of hardest hit process: 943
Highest hard pagefault resolution time (µs): 989355,673333
Total time spent in hard pagefaults (%): 4,555217

Hi kmaenpaa,

Sorry to hear that you are having trouble with the audio dropping out on your Saffire Pro 40, maybe I can offer some assistance!

Can you try disabling the following in your device manager:
- All network adapters
- All other sound devices
- Bluetooth
- Any card reader
- Modem
- Any other unnecessary device you might have

Then restart your computer.

Also we recommend Optimizing your PC for audio. The steps to do this can be found here : https://us.focusrite.com/answerbase/optimising-your-pc-for-audio-on-windows-7

The driver you would need for your Saffire Pro 40 can be found here : http://d3se566zfvnmhf.cloudfront.net/sites/default/files/focusrite/downloads/20454/saffire-mixcontrol-3.4.exe

If the problem still persists after attempting these steps, I would recommend contacting a PC tech, or your PC manufacturer to help with your system hardware configurations.

If you should have any further issues pertaining to your Saffire Pro 40 please feel free to contact us directly! Phone support is available at (310) 322-5500, Monday - Friday, 8am - 6pm Pacific Time.

Hi all,

I ran DPC Latency checker and had spikes. I disabled everything and even without restarting the culprit is my TP Link WiFi PCI card. It completely blocks the Saffire Pro 40 from working properly.. a 15 euro part is messing with a 400 euro part. Very annoying. I'll have to try out USB WiFi tomorrow and see if I can get both sound and the Internet on this computer.
