new computer - media browser hangs - drive or audio or auto-preview issue?

make sure the drives are all set to NOT go to sleep or hibernate...

Have you looked to see what background processes are running on your machine? 15-20 seconds is seriously long hang time... if you bump up your I/O buffers (Advanced Mode: Preferences->Audio->Synch and Caching) does that help at all?

I recommend caution in building Raid-0 volume sets.  If a bad block on either drive causes the controller to mark the drive set corrupt, you have the real risk of losing content from the entire spanned volume. 
 
If you have good backups of your applications and plug-ins, you may live with the risk.  I suggest you reconsider and recreate your raid volumes as Raid-1 (mirroring) instead.  There is a slight write latency overhead as the LSI controller keeps the two drives synchronized, but read speeds are slightly faster as you now have two heads to fetch data - controller deciding which head is closer to the data location.  And, if an entire drive fails, your volume is unaffected and available.  Once you replace the failed drive, the controller will resync the volume in the background and you can continue working.

Sounds like a complex setup...Why is C:\ a sata 2 state Drive?, and other storage drive sata 3?
Just out of curiosity ...is there some bottle neck in that?...is it a factor?...or are all Drives on Sata 2 ports?
 
Motherboard?
 
For the techies...are there issues with Nvidia drivers causing issues with sonar?
Perhaps turning off something with that cards Performance enhancement settings ? before doing any hard drive reconfig...?
 
Just some thoughts...not saying anything that is a solution...for I do not know...Just asking questions, may bring more to light for others who have technical knowledge in complex setups.
 
I hope someone can help you out there after...
 
Best of wishes.

Make sure that your floppy controller is disabled in the bios if there is one or at least that there is no 1.44 drive selected there, especially if there isn't one connected.  There have been reports in the past that scanning the system from the browser for a non-existent drive can cause this hang.
 
Does this help?

NVIDIA driver updated, lots of new options but I'm not sure what to look for.  All of the "3d" settings are disabled and everything else looks normal.  Took about 10 auditions before media browser hung for the usual ~20 seconds.

Well I had freezing happening with my now retired Sabertooth x58...and I believe a host of issues with that behavior and some other oddness in losing data or tracks from being saved to various HDD from the SSD base OS Drive running the software...when saving, seems it was a issue with the SSD and the on motherboard HDD controllers.
 
So...Some HDD controllers do not play well with SSD drives, and some HDD controllers are buggy...although some older boards have a SSD Port caching setup...it is not recommended to use this for a OS base SSD main drive....If you google the Marvel 91xx or tom's hardware site, you may find that taking this chance with your setup is a futile one.
 
Now what motherboard is asked to seek that info out...or point to it.
Some builders may have put this together not knowing about the issues with certain controllers failing on motherboards with SSD drives connected to them.
 
Also some ssd older drives have had bad controllers in them..which could cause freezing to occur in OS and Software.
 
Nvidia video cards I have no clue, but I remember reading something about them on this forum..So I went with ATI.
Just to remove any problematic Variables...
with which the system I was using had many issues...many, and I was using a crucial M4 sata3 SSD drive for my boot drive on a bad HDD controller now found to be the problem variable with that board...but that is not all...it also may have been, only once I updated the firmware for the SSD, that these freezes/crashes/buggy mouse behavior, and time line movement in sonar occurred, even slow response times after clicking on the play or record buttons, and loss of tracks started to show up...not to mention corrupted projects...most importantly slow boot times with the SSD installed as a boot drive showed something was amess with it, along with usb external drives....and no matter how much I tweaked the system, and bios to try to resolve, and updating the Drivers and windows, the problems worsened.
 
So before you start digging in to this Sonar Business, you should sort out any issues with the system first, if any.
Surely Sonar will help you gauge that performance with your system, but I would not do any real work until it is sorted out...
 
Just saying, and not that anything I say has relevance to your problems or system...Just look into it when other advice seems to not address the issues being found to manifest themselves as they are...
 
Some real good techs and software helpers are here...
 
But me personally...
I would clone the SSD to a nice 500gb or 1tb reliable HDD 7200rpm drive for a test run (WD Black ), if other solutions prove to be unhelpful...Just to say you checked all the balances and benchmarks to solve for.
 
I hope you put more info out for us, when asked...and hope we come to a solution for you.
 
But seeing into things as in "assuming", two E type xeon cpu chips may mean a server board....?...and after looking into those for my own setup and requirements ...I found none had sata 3 controllers of merit if any for proper SSD sata 3 Drive as a OS state of blissful with those tooted performance enhancement....So I went with Asus x58, but did not research the tooted sata 3 support on the board...and so I had issues...as do a lot of other people trying to use such a setup on older built boards using these faulty or buggy or problematic controllers...and some SSD drives also using certain controllers in themselves, also had in my past researching info based knowledge to be buggy...Some times that sort of thing only becomes known after the complaints, and RMAs come in...SO builders sometimes only look at specs...The real test is to make sure it works 100% with all installed or used gear and software...and chipsets, and I do not think builders have that luxury to test for long periods of time a build.
It only gets real work testing after market sale close....with you being the tester....not that this is true for all, as complaints and RMAs usually clear up the confusion when it happens...the bug is usually found, and corrected, and made known to builders through various means of communication....but sometimes it goes under the radar for some periods of time.
 
Just saying, and take it with a grain of salt, and pepper lightly, to be mindful, and do not overlook any variables, by saying the builder made it right....But look into it, make sure is prudent advise of merit...if you feel nothing else is solving your issues....and you have them, then someone didn't do their homework in the build, or something is not gelling with something else, a driver is not working with latest OS updates......or the software is at fault.
 
Cause you will lose hair, and sleep, and such, and possibly more...I believe, if you do not find the route cause and solve it out correctly ...and that will take time, and lots of questions need to be addressed.
 
Be well
 
Sir Les
 

Sir Les thanks for the response I will look into all of it with my builders.  Obviously we are trying to fix the issue but if it happens to be anything sonar-related I figure this is the place to ask.
 
I can recreate the issue on any drive including the system drive (C:) and non-ssd and non-raid drives.  I have not tried running Sonar from another drive is it worth trying to re-install?
 
I updated MOTU 2408 to the latest drivers... there was a very tiny update like .0001 to the version.  At first I thought this had fixed the problem but I got the browser not responding after about 30 auditions.  It does seem like maybe it's "better" but that's a very subjective thing from a small sample size.  And anyway it still will eventually hang.
 
The files are not corrupt, at least that I know of.  I have about 800GB of acid files that I'm trying to use and they hang seemingly at random.  After 20-30 seconds of hanging on a file, when the browser comes back to responding again I can audition the same wave file that caused it to hang with no issues.  It will also eventually hang when I try to audition standard 44.1 wave files like final mixes on my audio drive.
 
By the way I was blown away when I realized it was playing back my non-acidized standard wave files at project tempo.  This is new since 8.5.... very cool.  Though I turned off that option and it still caused the hang.

I'm confused, you are telling me a plugin screwed up playback with the media browser?
Well that's something new...!
 
Cheers..

Hehe... so can I chalk that up to a "background process" from #4 above??

I should add: new computer, new OS, new sonar software.   With these bugs I run into I have no idea where to begin looking.  Clearly upgrading all three at once is a horrible horrible idea.  I was forced to, just in order to go from running Kontakt 5.2 to Kontakt 5.3.

Sampled orchestral libraries are like the "King Kong" of drive-intensive demand. How big is that library? Despite the speed of ethernet, you are including other piece-parts in that daisy chain, and I would be much more inclined to seek a solution that fits in the same box as the DAW. Will they fit on an SSD? However....
 
Even saying that... I am sort of curious why that didn't have isues on an older machine... seems almost like the server/client in the new system is not set up "properly." I have no clue how that plug-in works, but now that you mentioned the server part, the 15-20 seconds seems like a "server sync" issue?

Could it be something as simple as the plug-in on the other computer not having samples loaded? SONAR may be allowing that plug-in to "verify sync" before SONAAR does its thing (hence the hang). Just a thought there, but at least you know that plug-in can do this to you!
