Sonar X2 Pro : Plugins Management 32bit/64bit

The search path is just a string of places for it to look for the target of the search.  I keep my 32-bit plugins separate from my 64-bit plugins because I do not want to have 32-bit plugins in 64-bit Sonar, as a rule.  The select few that I allow to be present are placed in a dedicated folder that is made available to both my 32-bit Sonar install and my 64-bit Sonar install as well.
 
If you are having noises, such as pops and crackles and such, that is a different matter.  You may have to increase your latency a tad to make them go away, and it is also possible that the nature of plugins that you have loaded into your projects may also be introducing some extra problems, such as plugins that are either CPU-intensive or that use look-ahead processing.
 
You may need to go through the process of isolating which one or more of the plugins is causing these problems, and see what the nature of that plugin is - possibly swapping out for a different one.

I don't have anywhere NEAR the number of folders specified as you do.
 
Sonar will 'see' the sub-folders, so if you specify C:\\Program Files (x86)\VST Plugins, in your path for the Plug-in Manager, Sonar will find all of the plugins that live in any sub-folder underneath the VST Plugins folder.
 
On MY system, I have a 32-bit Sonar installed, as well as a 64-bit version installed.  I almost always work in the 64-bit Sonar, but do sometimes work in the 32-bit Sonar if I am going to use a lot of 32-bit plugins for a given project.
 
My 32-bit plugin folder structure is set up in a main folder:
 
C:\\Program Files (x86)\VST Plugins
 
The above folder is where I place all 3rd-party 32-bit plugins that are not part of an installation process, such as ones I download directly (MinimogueVA, etc).  I also sometimes set up multiple sub-folders within the above folder, if a plugin has other associated files or documents, so I have things like:
 
C:\\Program Files (x86)\VST Plugins\JXPlugins, and that plugin's multiple files all live there.
 
The other thing I do for my 32-bit plugins is decide which ones I want my 64-bit Sonar installation to 'see'.  Those all still live in the 32-bit VST Plugins folder, BUT I move those plugins into another SUB-folder, called:
 
C:\\Program Files (x86)\VST Plugins\Shared (will explain further down)
 
I also own soft synth collections, such as Komplete 8 Ultimate, and it has its own installation process, and for that I let it add its 32-bit plugins to the C:\Program Files (x86)\Cakewalk\Vstplugins folder, and they all go there.  I do the same for any other 32-bit plugins that get put on my PC through an actual installation program.
 
BUT, I do not need to specify all of the sub-folders in the paths in either Sonar 32/64).  The plugin path for my 64-bit Sonar is simply:
 
c:\\program files\cakewalk\shared utilities\internal
c:\\program files (x86)\vst plugins\shared
c:\\program files\cakewalk\vstplugins
 
That's IT for the 64-bit Sonar's search path for plugins.  Again, Sonar will find any plugin within any folder that is subordinate to a listed parent folder, so any folder within the 'shared' folder is searched, and all 32-bit plugins in any folder that is under the 'shared' folder will be found.  All of my plugins for Komplete 8 Ultimate are found within the vstplugins folder specified above.
 
In my 32-bit Sonar, the simple inclusion of the c:\\program files (x86)\vst plugins path pulls in not only the 32-bit plugins that are not seen by the 64-bit Sonar, but also all of the 
shared' ones, because all of the shared ones live in a folder that is contained within (subordinate to) the VST Plugins folder.
 
I don't know if any of the above helps or hurts - I looked more closely at the list of folders you have specified, and you have installed a bunch of things in a bunch of places.  I approached my installations a bit differently, as explained above, and for me, my plugin paths are quite simple.  
 
They are that way for me partly due to choices made in altering installation paths for some things, and partly because of setting things up to take advantage of the way Sonar looks at folders within folders as it is searching.
 
For your paths, you could simplify it a bit by listing parent folders where possible, as Sonar finds the ones underneath anyway.  So, if you have the following paths listed:
 
c:\\program files (x86)\steinberg\vstplugins\e-mu
c:\\program files (x86)\steinberg\vstplugins\flux
c:\\program files (x86)\steinberg\vstplugins\soundtoys
 
You only had to specify:
 
c:\\program files (x86)\steinberg\vstplugins\
 
And Sonar would still find the plugins found within the flux, soundtoys, and e-mu folders underneath the steinberg folder.
