No output signal

Recently purchased a Tascam US 2x2 interface which came with Sonar LE
I have sound working from my computer  i.e Youtube and Bias FX stand alone (Windows 10)

Input signal  is shown in Sonar (guitar -> us 2x2 -> Computer -> Sonar), but no output signal on  the master channel  or any sound at that matter from Sonar

Its probably a simple fix but I haven't found anything that has addressed the issue.

Help would be appreciated

- Make sure your devices is selected in preferences.
- Check the routing on your audio track (This means input from your 2x2 and output to your master bus).
- Turn on input monitoring (Good advice from Syphus)
 
Then you should be good to go.
Also make sure you have speakers plugged in to the 2x2 output section or use the headphone jack.
Remember, once your 2x2 device is plugged into the USB port, your PC speakers will not be used.
Sonar/Your 2x2 uses separate speakers.
 
I only mention that last part because im not sure how much you know about digital audio and im trying to explain every small details. Welcome to the forum and Congrats on the New unit/Sonar LE

By this I think your saying they should use the Tascam's direct monitoring and not turning on input echo on the audio track in sonar. 

 
Im sorry, how do you possibly confuse Direct monitoring with input monitoring ?
 
""Each audio track has an Input Echo button that turn’s that track’s input monitoring on or off.""

That's why I mentioned it , of course we understand the difference but the OP might not. 
And in my world I would never turn on input echo on a audio track, especially with a lower end interface like a Tascam. In my world you will have a digital delay to the monitoring of anywhere between 7ms and as high as 30+ms depending on buffer settings. 
This is why all interfaces have direct monitoring so your hearing the music playback of the all ready recorded tracks ( computer) and then your new audio your recording ( input) which is direct monitored so there is no latency. Turning on input echo will result in hearing your latency. 
My comment was not to state you where wrong but to make this very clear to a new user. So sorry if you took it wrong not my intent ever. 

Yes 100%  that's the one instance you have to use input echo- when your using guitar sims. 
Personally I don't use any of that. I use outboard hardware.  As in,  I use my pedals and an amp, not biggy, I'm just of the old school camp who has no interest in digital processed guitar tone.  And as far as effect go I sing dry so I can hear what's going on without masking it. For client who needed reverb to sing, I have outboard gear. 
 
And my interface, a Scarlett and a Tascam, will be very close to the Tascam 2x2 performance wise.  So best RTL is 7ms . That's at a low buffer setting that will be on the edge of dropouts so I'm usually set at about 12ms RTL.  That results in a digital delay and annoying to listen to while tracking.  As you know there are hundreds of workflow situations , nothing is right or wrong if it results in a finished recording that you can enjoy. 

Got it working.
Knew it must have been a newbie mistake.

I hadn't clicked the Input listen on the channel. I also have Bias working. Had to find where the VST folder was; Once found, I just used it on the FX input under VST2.

Thanks for the fast responses.
