Hello,
 
I am running Sonar 8 on Windows 7 and have been experiencing a strange problem lately.  Hopefully someone else has seen this and can shed some light.
 
When I record an audio track, it plays back with about a 1 second delay.  So if I am recording guitar to a drum track, it does not line up accurately with the drums.  This only occurs when recording live instruments and vocals.
 
I use Presonus AudioBox.
 
If anyone can give me advice or suggestions on how to resolve the problem, I would really appreciate it.  Thanks a lot!

Have you tried going into preferences and adjusting your recording latency to a smaller number?

One second is a very long time. Are you monitoring the guitar through the DAW? If so try altering the mixer on the Audiobox to blend the incoming guitar signal with the DAW output and turn off input echo on the guitar track.

Do the audio transients of the recorded track appear to be that late in the track view or do they appear to be located correctly but aren't heard at the moment the Now time cursor passes over them? Which track is in time with the metronome if you enable it on playback, and is the click in sync with the Now time cursor on both recording and playback? The drum track is audio or MIDI? If MIDI, what synth is it driving?
 
As Steve noted, a whole second is way too long to be a garden-variety latency issue - half a measure at 120BPM!

Brundlefly - The audio tracks themselves are late in track view.  Typically I just move the clip so it lines up with the other tracks.  It's just a bit of a headache to constantly have to do that. 
 
In the meantime, I will try to play around with the latency as suggested.
 
Thanks for the advice so far.

First, I suggest you use ASIO driver mode if you're not already. Then make sure "Use ASIO Reported Latency" is checked in the Record Latency Adjustment section of Preferences > Audio > Sync and Caching. If the playback timing is still off with a new recording, then you'll want to measure actual latency with a tool like the free CEntrance Latency Tester (Google it), and enter the difference between what CEntrance reports and what SONAR detects (Total Round Trip latency on the Driver Settings page) as a "Manual Offset" (back on the Sync and Caching page).
 
Generally the Manual Offset needed to get perfect record latency compensation is a fraction of a millisecond (20-40 samples), and would not be noticeable in a normal listening context. But if the automatic record latency compensation isn't enabled, that might get noticeable if you're running a big ASIO buffer and direct-monitoring your guitar (or playing acoustic?).

Here's a screen shot (from X series, but the setting is the same) to illustrate what bundlefly is suggesting.

"Record Latency Adjustment" is what you're looking for.
When running WDM drivers you have to set the sample adjustment in the "Manual Offset".
HTH,
