You are not alone regarding the glitches during playback....I stopped updating SONAR since 2016.10 - glitches started from 2016.11. Didn't improved in 2016.12, so I also rolled back to 2016.10 after trying that (I need to finish a project very soon). This was when WASAPI support was introduced btw...
I haven't experienced any corrupted projects though.
yes ... and win10 had a number of changes right about the same time ... but still I can't let Sonar off the hook, as fairly recently I did again have one odd situation where a simple piano scratch recording (only one stereo audio track plus MIDI) was completely broken i.e. the audio files could not be played back, hitting record again resulted in the same garbled mess (i.e. "digital noise") but restarting Sonar without any other changes immediately fixed it ...
