This is for Windows 8.1 Pro but it is likely to be the same for Win 7. 
 
You'll find the config files in C:\USER\Your name|Appdata\Roaming\Cakewalk\Sonar Platinum\ aud.ini

Delete your aud.ini file.
 
Sonar will create a new one on boot up
 
This has solved a number of problems in the past

ok I reset the file path now...what now???????
 

It appears you have already been told. Rename aud.ini and start Sonar.

Audio (recorded) jumps a measure (bug)
 

 
Don't know if this is your exact problem but, I have this happen if I have a section looped (doesn't matter where in the project) and I hit record and snap is on, then the audio will be two beats behind (or at least a quantized value). If no section is looped, then the audio is where it's supposed to be. I just have to make sure looping is off before recording.

The resetting of the ini.file may have worked as I have recorded and the audio did not skip but I will test it out properly tomorrow as it is late in the UK.

I had this happen (audio moved right) a few times about 2 weeks ago. Hasn't happened since.  No problem with preferences.

I add a audio track and record vocals where I start singing lets say measure 2 when I stop recording and the sound wave is rendering it would have moved the audio two steps to the right. It happens every now and then no matter how I try to change the settings in the preferences once the preference box is closed then reopened the settings go back to its default setting.

This happens to me as well on occasion. I'll do a take and when I stop recording, the file mysteriously moves a couple of beats to the right...never the left. It seems like something in my system creates this lag. However, upon re-recording, this lag is rectified and usually doesn't happen again for that session. It also doesn't happen every time either, so it's nigh impossible to re-produce...I just live with it, since it doesn't continue with the next take. I just want to acknowledge that it occurs from time-to-time.
 
Preferences don't usually reset, although it has happened on occasion. EQ settings in Pro Console will also go flat on occasion. Open the same project up in X3 and settings are back. This one is of more concern and frustrating that the other 2. 
 
 
 

Sorry for duplicate post. Slow internet in my hotel in Turkey...

Hi. Could this on a project created in earlier versions, that used the Sonitus EQ? The newer versions of SONAR uses the Quad curve EQ, and not the Sonitus. I had this happen to me before I knew about the different EQ's in PC.
Best of luck.
