So lately my Onkyo HT-R640 has started making a strange clicking sound, audio drops out for a few seconds, and then comes back. It's the same clicking sound it makes when I switch video inputs, but when it does this, only the audio drops out -- video stays put.
It's very strange. Sometimes it does it every couple of minutes for a few hours, and others it just does it on an irregular schedule. I am not really sure how to go about debugging this.
My setup: Comcast -> Tivo HD XL -> Logitech Google TV -> Onkyo HT-R64 -> Samsung UN32D4003
It only started doing it this past week, and I haven't messed with my setup in months.
Any ideas?

If its a digital receiver it could be having "timing" issues, where its occasionally failing to keep the audio in time with the video.
In pro-audio gear, there is something called a "word-clock" which ensures that all connected devices in the signal chain all use the same timing. So for a simplified example, if you are playing a CD, those are encoded at 44.1k sample rate. The clock would make sure not only that all your gear is also running at 44.1k, but that they are all taking samples at the same time.
Sometimes cheaply made gear has a poor quality clock where it doesn't take perfectly even samples. That can introduce little clicks and pops as well.
