Does this happen on all file types or just MP3s for instance. If it happens on all file formats (PCM, MP3, AAC, ect.), this sounds like (no pun), the Magix Low Latency 2016 driver issue.. removing the Low Latency driver usually fixes it. However you may first want to try updating Sound Forge to the latest build. And/or resetting SF to the factory default settings. In the 'File' menu,. select "Reset all preferences and cached data".. and restart SF.
