I’ve had this problem in 5.5 and CC, and just figured out what’s causing the problem for me. I’m on a quad core AMD PC, but the issue is related to my audio card. I do high end audio production, so i have many different audio drivers. Every now and then, after closing VLC after watching a movie, I have no system audio. Or various things cause it in my audio program. But lately, i’ve had it creep into Premiere. MY problem, has to do with my audio driver. My quick solution is this:
Right click on the speaker icon in the system tray. Choose Playback Devices, which pulls up my Sound window. By the way, I have Show Disabled Devices on. This helps me in the big picture of things. But anyways, find the driver you use for your audio output, which in my case is an external preamp that acts as my sound card. Right click on that driver and choose Disable, then re enable it. This solves the problem for me. To prove it, you can right click and choose Test. You should hear no sound. After disabling and re enabling the driver, run test again, and you should hear audio. Premiere then continues to work like normal. I racked my brain for days to figure this out. And again, this works for me with my crazy setup. Hopefully, this might work for you if nothing else does. Good luck and happy editing. Thank you all for these forums.
