* Upgrade to X3E (you are running X3C according to your footer).
* Run windows update several times, get most of the optional updates installed as well.
* Update firmware and drivers of X32 to latest (I know you appear to have ruled this out but would do this anyway).

More importantly...

* Update your motherboard BIOS
* Run Intel driver update, get your chipset updated:

Thanks ... but apart from the footer everything is up to date (Sonar X3e, Win8.1, X32 firmware) ... as new as it can get & put through extensive testing before the show ...

from what you've posted, i think i'd be looking at the environment differences - power supply, networking etc - any way you can get back to the venue and try and reproduce?

yeah ... that might be the thing to do ... same rig, plus UPS to see if it would solve it ... and if, not at least get some Guiness on draft for further inspiration :-)

Sorry to ask again but...
 
What about motherboard BIOS and Intel driver update?
Make sure you have the latest chipset drivers.

Thanks, Bob for trying to help :-)
 
Yet this is probably none of the issues you have spoken about ... as Sonar did not crash (it was the audio interface that was receiving something from Sonar that it didn't like and hence decided to reboot) ...
 
It also happened with the tablet PC in airplane mode i.e. all external connections / adapters turned off (blue tooth, WIFI, ...)
 
Sample rate is at 44.1 kHz, no 32 bit plugs installed (there isn't even a single plug-in used as Sonar only plays back 2 - 8 monotracks and sends them unprocessed to different channels of the mixer) ...
 
Anyway, any suggstion that will make me think about something I haven't thought about yet is much appreciated.
 
Thanks, Rob

Hi there,
being a pc technician, I have seen this happen quite often, esp. with laptops that don't have the power to fully power the usb ports and was wondering, this usb hub you said you are using, is it passive or powered.....if you are using a passive hub(not powered by a actual ac adapter) then I would suggest swiping it out to a powered usb hub.
It sounds like to me, the mixer is not getting enough juice to stay powered up through the usb and by what Robert said, try plugging it into a usb 3.0 which has more of a power output than the older speced usb 2.0 and below....
I hope this helps...

no worries, mate ;-)
 
just checked with the Intel Driver Update Utility ... all up to date (only lists an available HD Graphics Driver Update ... which I may run later ... but that can't really be of importance in my particlular problem ...)

So I'm guessing you won't be able to give this all a real test until your next gig but if you remember I'd be interested to get an update as to whether you get it working and what you changed. Also I guess if the problem is somehow being induced by the venue power or something I'm wondering if that will be a constant in the equation (as in if you try this stuff out in the same club using the same power source).
 
Anyway to continue the USB train of thought (and this may have been covered)... you have optimized your USB ports to use the highest performance settings within the Windows Power Management options, right? Windows by default is usually set to power down USB ports and all sort of other crap which can cause these types of dropped signals when doing streaming tasks like audio and video. Laptops especially have these power saving schemes going on. Check the hard drives to to make sure they are always staying powered on. Not sure if that is even a problem with SSDs because I've never used one but perhaps.
 
Cheers.

Bertl : when you posted : just checked with the Intel Driver Update Utility <   A red light went off , your support for that unit is not at Intel its here :

Note : its not the latest chipset driver or other drivers... you require  ..but in fact the right ones !

Notwithstanding there are from 2012/13 they are the correct drivers known to be stable on your unit

In fact it's both. Acer simply copies the Intel drivers from the Intel site to their site so often it isn't up to date as Intel.
Intel driver update website should have the latest Intel drivers inc chipset (assuming it is an Intel chipset).

Acer will also have drivers for other third party peripherals which are often more up to date on other third party manufacturers website (again Acer just distributes them). The only thing unique to the Acer site as far as downloads concerned is the BIOS as often it is custom built for the machine's motherboard. You don't get BIOS downloads via Intel autoupdate.
 
As long as you use automatic detect on the Intel site you shouldn't go wrong and you will have the latest Intel stuff. Acer may supply additional drivers (may not be the latest) and is the best source for getting the latest BIOS.
 
Cheers..

Once again, thanks for all the help :-)
 
I meanwhile also did the BIOS update just to be on the safe side ... and verified agains Acer website that the rest is indeed up to date ... thanks for all those links to guide me where to find the right drivers
