With the X3 and now 2015, opening a web browser nukes the audio in sonar.
 
So I am still using 8.5.3 to record from the web, and dubbing tapes.
 
And it is very inconvenient when opening the web-help file.
 

usb root hubs in device manager under universal serial bus controllers...each hub is a port...sorry for the confusion...properties, one of the tabs has always on...just to make sure, when opening your Sonar, things are not being turned off by windows...to save power...yah power management tab, de select allow computer to turn this off...that one, on all hubs.

Do you have onboard audio chip on the motherboard?..is it enabled in device manager?...try making that your windows default....then try again to play back in Sonar with the usb audiiobox....trouble shot the ghosts is hard, but you gain so much experience on the ons and offs...to get things into bliss...if this does not work for you, try with it as set, and reselect  main outs again in sonar console, and check preferences, try unselecting asio, and reselecting...just to clear any locks windows may have had or other app...then...driver update, still with it not as MS default...if that does not work...then consider reinstall?...or someone else might find something to help...so be patient...baby steps!

I have found Firewire in my setups in past ranglings to make all work impossible to do, to cause much issues with nic cards or chips onboard running, when needing audio and Sonar...yah open up the help, and all is toasted in the project!...but since I moved to thunderbolt 2 interface for my audio desks, on firewire adapter, internet works fine...do not ask me why...I can also turn on wi fi...and it works....just saying through my experience so far...but I do turn off the wi fi any hoot...why test faith and tech when one does not need to pull out any more hair than necessary?....Just saying.

I do have onboard audio but I no longer have that speaker system hooked up... this system has been working for me for a long time and I haven't changed anything so something must have happened within the software... it is clearly something catastrophic, I'm out of ideas.

..note..using onboard device for MS default audio playback...using a cable form onboard audio out, to external ins into external audio device, can be recorded..and play back web content through onboard device, through that cable,..into external device... into your daw with next to no issues, when setup is done to allow it...and there are issues with video HD HDMI audio...so one might want to disable that....wink.

I know you had it working, but as I said MS updates might be behind this...so letting your audio solution be free...might help solve any locking to odd sample rates, or just hogging the device exclusively for MS or other third party player or user installed that does not let go of the driver.....thus your audio goes grey...locked out..or not available to Sonar...but...I think, if you fiddle that out of the varrible, it leads to a reinstall of either latest drivers, then Sonar lastly...because if one does not root it out as hardware, and you just reinstall...it may be it does not solve the problem....Just saying.

Check power settings to make sure the USB item is set to never save power.
Do the same with every USB device in the Device Manager:
 start from the bottom: USB Root Hub /  Power Management tab: uncheck and OK
 
I suggest disconnecting the audio device, power off and pull the plug to discharge all caps.
Power on, at the desktop, connect the audio device and test.
 
If no joy,  download the latest drivers, uninstall all stuff for the audio device, unplug, shut down and unplug the computer, restart and follow the instructions for installation.
 
 
 
 

I seem to be back. I uninstalled and reinstalled Sonar, then had to unselect the Audiobox drivers, apply that, and then reselect them... then I got sound again. I hope it holds... thanks guys.

Seems to me, it was the driver being held by MS win or other app not letting it go....So think about making your external usb audiobox not the default play record for windows OS, use the onboard sound for that...might clear you from future lockups?....have fun.
