Some defintly wrong in X3 ....check the synchronasition option in audio setting ...i also noticed that the asio latecny doesn't appears ...you have to open the interface asio driver panel for it to appears !!
 
i don't like what i expereinced with X3 since few hours ....
 
check my thread also ./...

I think what people are trying to troubleshoot is whether you have explicitly selected the driver mode to be as ASIO - this is in Preferences | Driver settings. SONAR doesn't default to ASIO, so you must explicitly select that. In the screenshot you posted of X3, from the names it looked like you were in WDM mode.
Now if you select ASIO as the driver mode in SONAR X3 and see *no inputs and outputs* listed when you go to the devices page then there indeed is a problem. If X2 sees the drivers in ASIO mode then X3 should also see them.
 
There is only one change in X3 that was made to fix a similar problem where some M-Audio drivers were not showing up. It would be pretty bizarre but its not impossible that this fix has negatively impacted the detection for the MOTU drivers. If you PM me your email info I will try and troubleshoot some more things with you. Don't bother reinstalling SONAR at this point since the problem isn't an installation issue.

Arrghhh! Isn't that on the Playback and Recording page?

OK, now there are drivers available to choose from. There weren't any other drivers available in the Driver Mode for some reason. It must have been a glitch I don't know. But, my computer locked up and I rebooted it. Then, after that I can select the ASIO in the Driver Mode now. Weird. 
 
Everything seems to be cool now. Thanks everyone for the help!

Cool...  Noel was able to fix your machine through osmosis. 
 

Edited - because you seem to have finally gotten ASIO set as your driver mode, and as far as I can tell you are now OK, so I nuked what I had originally written.

Jack: see you are running this driver there ....  http://www.nvidia.com/download/driverResults.aspx/30520/en-us

Any body know why this ? 
 

 

@Zo - please clarify your question.
 
Also, your input/output latency values are quite high, resulting in a 28.9 millisecond total round trip latency.  Your input latency is 11.8, and output latency is 17.1 - for comparison, my input and output latency values are both 3.7 milliseconds, with a total round trip latency value reported as 7.3 milliseconds.
 
The 'Number of Samples' values Sonar reports for you are: 522 for input, and 752 for output, while for comparison my values are both reported at 176 samples.
 
I see your Sonar Sample Rate is 44100, and am imagining that your audio interface is also set to 44100, which is fine.  Different audio interfaces implement controlling the ASIO Buffer Size differently, but whether or not it is specified as a straight buffer size (like my Presonus AudioBox 1818VSL - set to 128), or if your interface specifies it as a number of samples (sometimes a slider is used, others use a pull down showing several choices for it, that value represents the size of the ASIO Buffer.
 
So, my question to you is, what is your ASIO Buffer Size set to for your audio interface?  
 
If it is set too low you can get dropouts/crackles, and if set too high you will add latency (as seen in your screen shot above), which can really be a pain.
 
My suggestion to you for a reasonable starting point for your audio interface settings would be a sample rate of either 44.1 or 48, and an ASIO Buffer Size of either 128 or if expressed in Number of Samples - set it to some number just a tad under 200 (mine is 176), with a record bit-depth of 24 bits.  Please note that it is recommended that you power-cycle your audio interface anytime you change those settings, in order to get a complete refresh of its associated memory.  (exit Sonar prior to cycling the interface, as well, if audio interface settings were changed).

hi bob .....
 
nope my latency is high (512 sample) i was pointing that i have no infos on that exepte if i open the ASIO panel !!!!
 
is it the case for you too ? or is it my system ?
