Yes, it plays after a restart. It pays through all any of the voice or music that I am playing on my computer or from any website,. It's sporadic but constant. It's playing more frequently now while I am typing this message. The company (Sound Blaster) support have not idea what it may be. They feel it may be a conflict with the Win 8 upgrade. I have re-installed, custom installed and I have exhausted deleting other software on my computer. It plays totally involuntary. If I join a webinar it plays. I would appreciate any advice you can offer.
