Welcome to the forum!
If I understood correctly, you do the recording with R16 and then import the audio to SONAR. It would be more straight forward to record directly to SONAR, IMO.
I can't think of a reason that prevents the track from running when you hit PLAY, unless it's a 64 bit/32 bit conflict. Even if you didn't hear anything, the track should run. Even if Scroll lock was pressed, you should see the meters moving.
Did you set up SONAR to use the Realtek? Is it chosen in the Options-dialogue for both record and playback timing master?
So you imported wav-files into SONAR, but when you press play, nothing happens? The Now-time pointer does not move, right, but do you see it ( I ask to eliminate the possibility that the audio is imported far from the project start, and now time- runs on an empty part, thus producing no sound)? If the track doesn't even start to run, that does sound weird.
Could it be a 32 bit/64 bit conflict?? Did you install 64 bit-version of SONAR or are you running in 32-bit mode.
I don't know all the details about what can be caused by bit depth-differences, but someone wiser will tell more.
I'd say R16 is your soundcard, not the Realtek. For starters I would disable the Realtek, see that it is not selected to be used by SONAR in the Options-dialogue. You'll never be able to do fluent DAW-work using the onboard sound chip.
Being not simply an audio interface, I think R16 has more tweaks than some other gadget.
You must download the newest ASIO-drivers for the R16 from Zooms site, if you decide to use it.
If you want to stick to Realtek, try ASIO4ALL-drivers (free DL). If it's only mixing you do with SONAR, the Realtek will do, I guess.
Audacity, being a very limited software, is designed to work with lowgrade soundcards and MME drivers (the poorest there is). SONAR and Cubase, being full size DAWs are built to require an audio interface of proper quality, to be able to perform much more demanding tasks than Audacity can do.
SONAR wants to offer all the options a pro user needs. The variety of different setups and tasks is so huge that it's logical to leave it for the user to define. After all, it's the soundcard driver that is the essential unit in making the sound playback/recording/syncing, and it's a third party software, over which SONAR can't have any control.
