Have you updated your drivers to Win7 for your audio interface (post #2 - not sure if I missed that you had, but that is important)? Making the jump from XP to Win7 will needs drivers specific to the version you are running (32-bit/64-bit).

Yes, the old XP drivers are not the ones for W7. I did the the update on M-Audio's site for my Windows 7 32bit ser. pack 1 which is 6.0.8.
 
Could plugins being blocked on Firefox have anything to do with this?

I ran that DPC Latency Checker with Sonar off but have no idea what I'm looking at. The DPC Latency Checkers three setting as it runs says:
Test interval    976
Current latency   From 23 to 177 (sometimes higher spikes) High as 1600
Absolute      177 (sometimes higher)
 
In Driver settings looks like both playback and record have the same settings:
Play back timing Master:   1. M-Audio Delta ASIO SPDIF out L Delta 1010  
Record timing Master:      10. M-Audio Delta ASIO SPDIF in L Delta 1010
 
Thanks, al
 
 

I know there is a lot of new stuff to absorb.  :
 
A spike of 1600 in DPC Latency Checker indicates that you have some sort of intermittent process that is killing your ability to handle audio streaming.  
 
These 1600 ms spikes - they are red?
 
And, in the text down below the graph, did it indicate your computer would have trouble doing audio streaming?

Oh, and your input and output devices are listed in Edit>Preferences>Audio>Devices

Bob, I just read the interpretation of the DPC test, Thanks. In device manager I do have a USB device that has problems with the driver not working properly, I tried to update but Windows had problem installing the driver it found. I disabled it and still the static noise over the music playback. I'll go to Gateway support for my PC and try to download the correct driver there.  But if it was causing the problem, disabling it would have worked.
 
OK, I ran the latency checker, Sonar closed. It stayed in the Green for the most, no Red and when I first turned it on jumped up into the Yellow but never high enough to give the reading in the text about problems in the device manager. Once it did in the beginning but just for a second when first started it. As I said above I checked out the device manager and notice that a USB port's drivers were not working, etc. Disabling didn't help but no red warnings for problems.
 
Were do I go from here?  
 
 

Hi:
I was using 3 Delta 1010s up to about 2 weeks ago.  Now I am using something else.
For Win 7, I had to disable Firewire, USB 3 in BIOS, as well as Turbo, and 2 timing factors in BIOS as well.
This was recommended by M-Audio itself, before they got sold out, on their Delta forum.
What I find strange is that why the OP did not go the 64 bit version of Win 7 and Sonar 64 bit as well. Or did you?
Also I always had better luck using WDM instead of Asio.

At first after I loaded W7 and installed Sonar Producer I had no sound, it was on WDM. I couldn't get it to play on WDM. What other settings did you make after you selected WDM?

OK, thanks for going back and checking.
 
I do not at the moment have much in my head as to what is causing your issues, other than that 13.2 milliseconds is a little high for your Total Roundtrip Latency.
 
Please let me know what your ASIO Buffer Size for your audio interface is.  (might also be expressed as number of samples, or something like that - different vendors call it different things)
 
It does not sound like you are having bad enough device driver issues to account for the static on playback - the trick is figure out what else it could be.  When not caused by things like a Wi-Fi adapter or something like that, it''s usually either settings, plugins, or sample rate, driver mode, or bad drivers.
 
It isn't sample rate, and as I understand it you are running in ASIO mode at the moment, and your devices don't seem to be spiking in the red for DPC latency, as measured by DPC Latency Checker, and your Total Roundtrip Latency isn't particularly high - little though.
 
Just for grins, what happens if you run Sonar where you only have a single Delta plugged in?  I just want to try to simplify things until the problem area is found.
 
I don't know enough about setting up 2 of those on a single system (other than syncing up clocks and such), sorry for asking you to try that - but it is just for testing for the moment. :)
 
I will also continue to dig.  Please post back with the requested info, and also if you get a chance, pull one of the deltas and test it out with just one, and post back the results with that.
 
Thanks so much for hanging in there - I wish I was better at figuring out some of this stuff.  :)

I forgot to ask - I believe the Easy Transfer process kept you at Windows 7 in 32-bit mode.  Is that correct?  Are you running Windows 7 in 32-bit mode?  
 
If so, why?

ASIO buffer size I think is 256 (samples), set on the fastest but looks grayed out (the fastest setting only), if I'm looking at the right setting in driver settings, mixing latency.
 
Bob, to pull one sound card I'm afraid I'll have problems getting the two hooked up again. I did this years ago and it took a while to get things right, can't remember exactly what the problems were but if I remember correctly I just have the two cards with one's out going into the others in and then out to the monitors.
 
Remember everything works great still when I boot up that old XP HD w the same sonar although I have just Sonar Producer in the old XP Sonar and the Expanded patch in the W7 HD. I'd have to take out all of Sonar and reinstall skipping the Expanded edition to get just Sonar Producer X1. Could Expanded with W7 be causing a problem...?
 
Just knowing that everything works fine on that XP HD drive makes me think of some kind of conflict with W7. I even tried older drivers, no dice.
 
When you mentioned the most likely culprits, "plugins" is jumping out. Sometimes my you tubes are choppy, and way out of timing outside of anything connected to Sonar. The Firefox's latest update has a plugin setting that I think plugin are off unless you turn them on for each site. But I don't know how that would relate to Sonar. I'm not a PC expert by any means.
 
Bob, I'm running W7 32 bit instead of 64 because my PC memory max is 2 GB, non upgradeable, 64 bit needs at least 4 GB.
 
Thanks, for helping,
