SONAR 8.3.1 NO SOUND on UCA222 interface

Uninstall ASIO4all and use the native behringer driver for that device.
After you install the UCA222 driver,  tuen your interface on and wait 10 seconds and then start sonar up.

If sonar doesnt performa a wave profile, go into options > audio and switch the driver mode to WDM and then click the wave profiler.
After it runs the profiler, go into the driver box and check all the ins and outs and then go into the advanced box and make sure the recording and playback masters are set to your UCA222

Just go to your master bus and asign the output to main outs 1/2 and then make sure your main outs 1/2 go to your sound cards outputs.
go back into th eoptions/audio/driver tab and check all ins and outs like i said above adn then go into the advanced tab and do that also. You need to check the settings after the profile

CJ - sorry but you're wrong.  the UCA devices from behringer don't have native ASIO drivers, nor do they have WDM drivers.  behringer's website recommends and links to ASIO4ALL for their drivers.  it's either ASIO4ALL or windows' USB Audio Codec.

lexx - USB Audio Codec is what you're using in this mode.  behringer has no specific drivers for this device, so if you don't use ASIO4ALL then you will be using the windows USB Audio Codec.

at this point, if you chose USB Audio Codec in the OUTPUT of your MASTER and METRONOME buses then you probably will work fine except you'll have higher latency than you would if you went back to ASIO4ALL.
 
and to locate the master and metronome buses, they should be at the bottom of your screen in the track view, or on the far right if you're in console view.  they could be hidden, and if so, click on the bar at the bottom of the window and drag up and it should show the bus pane.  if you can't find it that way, click on VIEWS.  I'm not in front of sonar right now so I don't remember exactly where to go from there, but you can find a VIEW in there which will show the buses.
