Ive tried creating a new sequence. I have Panasonic P2CMS Ive used the last two years. I recently started using an iMAC 3.5Ghz Intel Core i7/8 GB using Premiere Pro CC. Ive been using this system for about a month with no problems, and just today clips im attempting to import and place on timeline dont have audio track attached. Audio and video will play in the source monitor, but once I try to put it on the timeline it only has video track. I've rebooted system, and re-opened premiere and it will work for a few minutes allowing me to put clip on timeline with audio and video, then stop again.
The sequence setting is the same that I've used the past few years, up until today.
