Premiere pro no audio when dragging playhead

Very recently (the last couple of projects) the audio has stopped playing back when i drag the playhead and for the life of me i cannot figure out what is causing this. If anyone out there can help me figure out what setting to change I would be very grateful! The audio works just fine in playback, no skips and rendering does not solve, it is only when dragging the playhead and I need this function and being without adds hours to my edits! Please help!
