Platinum Audio engine going south Win10 - Not playing well with RME UFX

I've had a similar symptom ever since moving to Win 10. All audio goes silent, not just SONAR. It doesn't happen often, perhaps once a week or less, but it's most likely to occur after the machine has been idle or asleep. I didn't have this issue prior to W10. I've been blaming it on the interface or its driver. I do not use the same interface as you, but like yours it is a Firewire connection.
 
I have a simple workaround. When it happens, I change my ASIO buffer size. Doesn't matter what I change it to, the point is to force the interface and/or driver to re-initialize. Sound always comes back immediately and I don't need to restart any applications.

It is definitely Win10. Reverted back to Win8 and no issue with the audio engine sitting idle.

I have not seen this.  However I can't recall leaving my audio system on for lengthly periods of time at idle. My system is set up with audio and MIDI on when I turn on my overall audio and MIDI system. its all on a single switch. The computer is independent of this.  
 
I do know that Windows 10 has power modes that are not ideal for audio. Be sure you set up your Windows 10 to not go to sleep or cut off USB after an idle time. Win 10 is meant to run on tablets and laptops as well as desktops. Right now I have my desktop set to never go to sleep. Also be sure you disable core parking. Further because Windows is always updating you may need to check these settings from time to time. 
 
Most settings are in the settings/system but there are settings you will need to goto in devices in control panel. 
 
I'm not sure this will solve the problem but it can't hurt to try. 
 
 

Just talked to the Synthax support. They have zero reports of this issue. 
 
I updated the drivers and firmware to the Feb release so everything is up to date and I am still having the issue.
 
Is there anything from a SONAR pov that I can do to help them understand the issue? If I can't get this worked out, I am going back to win8 again.

just tried the power settings to performance in Win10. Deleted the AUD.ini, but didn't see any reprofiling. Audio still distorts and then fails to play. The meters still work in SONAR, but TotalMix is not showing any audio activity.

Not happening here with the TASCAM US-20x20 USB 3.0 interface.

I tried leaving an audio clip sitting in Sound Forge and I did not experience the distortion or missing audio. I let it set for 5 hours without issue. 

How can I say this is not a SONAR/RME issue? I don't think I can at this point. Running the test with X3 now.

Thx John. It is a 64-bit standard version and ASIO drivers. WDM doesn't work for my UFX. Just let X3 sit for a couple hours and not exhibiting the issue in X3. This looks like a SONAR Platinum issue with RME and Win10 64bit. Whatever the default update version of Win10 is. 

thx for the reply Dave. I looked at the USB Hub settings and the box to allow the computer to turn the device off was unchecked. The UFX has it's own hub and is high speed.

I've had it happen to me a few times lately and I'm on Win 8.1 and the latest version of Platinum.

I will try to get that info Bob. Again, it doesn't happen at all for me on Win8 and platinum.
 
Noel said he has seen it, but have not heard anything from him since. So it is a known issue.
 
I am back on Win8 for now. I may find some time over the weekend to go back to 10  if anyone has any other suggestions.

I just wanted to report in here and say that it doesn't happen at all with my UCX (also over USB, latest drivers), Sonar Platinum 64-bit and Win 10. I do always make sure to plug my UCX into the same USB2 port (my computer has USB3 too and they do say it's supported, but still). I don't even have the very newest of laptops (quad core i7 2670 at 2.2GHz) but I can run most projects continuously at 64 samples. I know it's not an UFX but it seems close to it in hardware and drivers.

It's been rock solid so far. Only Melodyne related crashes here, as usual.

I have had this happen to me with an LS 56, latest focusrite drivers and ........ W10.

It also happens when Sonar is not open but the machine has been idle for some time.

I need to check my power settings again, i have also heard that W10 updates revert certain settings back to default.

Cheers,
Jerry

I'm using RME UCX, sonar platinum x64, Windows 10.

The only time I have interruptions with mouse, USB hub, or interface seem to be related to update installations.

It would make sense that when idle Windows may attempt an update if update services are running. This could interrupt the RME.

If someone has a pc where the install was repeatedly being attempted and failing, it could maybe cause this case... ?

So, if you check the logs... application... For errors after the problem, do you find anything? Right click my computer choose manage and find the Windows logs. They take a minute to populate.

Hi. I am running a RME Ucx, latest drivers (USB), latest firmware, latest SONAR and Win10 X64 (fully up to date). I do not have any problems with the audio engine cutting out when leaving SONAR for hours, or even overnight. 
All the best.
