please communicate clearly
"even if" - hypothetical meaning it isn't reality yet.....
"even if i have a stereo track selected to record in sonar" - hypothetical meaning you haven't recorded anything yet.....but only set up a stereo track in SONAR (for a mono input)
"i can only playback from the left speaker" - still meaning you haven't actually got a recording in stereo yet so playback must mean you're playing an instrument (mono) to try to hear stereo. That confused the issue right there.
I actually read everything you wrote many times to make sure I was understanding your statements. Now that you've clarified a bit in your subsequent reply, I don't know how the Session IO works or what it even looks like or what it has as outputs. But there's a lot of different places this can go wrong for people which could mean mono cable in a stereo jack (one channel is carried); it could mean you think you have a stereo track with stereo data but only have mono data in a stereo track.
You also confuse with two different things so I'll ask for clarification....
Is your problem that you're only hearing left channel sound through headphones as per "it plays that rhough only one ear also"?
Or is your problem "only "session i/o left" driver available to be selected in asio mode"?
You shouldn't have been talking about playback in one ear if the problem is that the NI drivers aren't communicating 2 channels to SONAR. So, if you can only pick output of one channel then there is indeed a problem with NI hardware and you should go to NI directly with that because that sounds like an issue.
Most of us here try to help when and where we can but sometimes how the question is asked misleads us to try to solve where the actual problem is. In this case now that you've clarified, you're saying you only get one channel exposed from the hardware? That's a driver issue and has nothing to do with SONAR so try going to NI's forum and see if there is anything there for help.
