Still looking for a solution as to why I'm having constant pops and clicks during playback or recording since my Foxboro update two weeks ago. Cakewalk support couldn't figure it out the first time I called them, and since then I've installed a new solid state hard drive, thinking maybe the issue was there. Of course, the first we did was uninstall/re-install the interface drivers, which made no difference. The only thing that alleviates the problem is setting my ASIO driver setting two ticks higher, but that leaves the system borderline unusable for overdubs with a latency ready of 28.9 ms. Here's a couple of screen shots of how things were set before the Foxboro update and what I have to use now. Maybe the update timing was just a coincidence, but something happened.
The computer has no anti-virus software installed, as it is only connected to the internet when necessary for updates, etc.. Ran LatencyMon and it says I should be able to handle streaming audio with no problem. Any thoughts are appreciated.

Hmmm. can't seem to get the screen shots to upload. No matter what I try, I can't seen to get a.jpg of my screenshots to load. Any help is appreciated.

The images must be hosted on another site and the links posted. I upload to http://imgur.com/ then click the BBCode option and paste the result in my post

Thanks, I'll see if that works for me!

The easiest way I know to rule out a particular release of SONAR as the cause of a problem is run another version of the software. If Foxboro appears to be a problem, roll back to the last version which worked as see if the problem is still happening. If the installers are in the download cache the roll back takes seconds.

What is LatencyMon showing exactly, and how frequent are the clicks/pops? And what do your CPU core loads look like in a typical project? 96 samples should be okay if DPC latency is low and stable (most important), but intermittent spikes could still cause an occasional pop, especially if your CPU load is high at the same time. Sometimes a particular plugin can put a lot of load on the first core and blow the whole deal.
 
The non-ASIO-buffer related driver and hardware latencies are on the high side which is not helping keep total latency low. Will you lose interface channels if you increase the sample rate to 96kHz? If not, that might let you get more reasonable total latency with the larger buffer size.

DPC latency is under 100 . Crackles and pops are very constant at my 11.9 ms setting - like a garbled bad radio transmission. Better when I move up one slide setting, goes away, pretty much when i go up two slider settings. My CPU load shows about 45% - which seems high, given I have a project loaded up with just a piano track and a vocal. FWIW, track count and larger plug-in counts don't seem to make the problem worse.
 
Maybe I'm wrong about the CPU thing - in the performance tab the icon of the disk drive shows about 45% - the icon of the chip or whatever below it shows about 10%

Do you get the same using WDM? Or are there no WDM drivers for your interface? Do you happen to have ASIO4ALL installed on your system (long shot, but it caused me a lot of trouble). Any other recent audio/video stuff installed?

I remember Craig encountered an issue where disabling his graphics card's HDMI audio devices in the Windows Device Manager significantly improved his latency. Maybe your graphics card got an update that made things worse for you?

No WDM drivers for my interface and not using ASIO4ALL. Rolled back to the version before Foxboro (Everett or whatever it was) with the same results. Tons of drop out, crackles, distortion in general. Then, I updated to the Gloucester version released yesterday and had a major improvement, although not the performance I had previous to this mess. Called tech support again today and we're all still scratching or heads a bit. Good thought on the graphics card audio drivers, but disabling them made no difference.
