I have a relatively new Premiere XL4. A month ago I suddenly lost audio through the HDMI connection (Pioneer AV Receiver, 18 mo old). Video is fine but audio just "pops". Tried a new HDMI cable, no effect. Switched to a different HDMI input on my receiver, problem resolved. Now, a month later, problem comes back. Same result- switching HDMI inputs fixes the issue. I have a cable box, blue ray player and xbox 360 all connected to the same receiver with HDMI and no issues at all. I realize that I can switch to component video and digital audio but I really shouldn't have to. Things ought to work! Any thoughts?
