I have frequent (random, but at least every minute) and momentary (1-2 second) losses of audio out from the Comcast Motorola DCT3412 box using the optical connection. I currently run the optical cable from the cable box to my sound system, and use the HDMI output from the box to the television.
I do not experience these audio losses when using the Bluray DVD either when watching downlad or discs.
Any recommendations on how to correct would be appreciated.

I have an older DCT-6412, and see this on at least two channels (BBC America HD and WTTW [Chicago PBS station]). Oddly, if I review back, it does not repeat. So far, it's only those 2 channels, at least of those I regularly watch. It has done it with two receivers (I recently replaced mine.) It is connected via optical. My 6412 is an older P2 version and has DVI, not HDMI, so the only digital audio is through optical or coax.
The TV is connected to the cable box via a DVI/HDMI cable. It may be some slighly weird sync issue, although I don't understand why it's only those two channels.

For me it's every channel and it's worse in the evening (more people accessing the service?).
I will try to feed the box to the TV and then feed the TV audio out to the receiver. Maybe that will work. Haven't tried optical cable yet, although from what I've been reading, it's not a solution either. I also went into the DVR menu and switched the "HDMI advanced menu" settings to PCM and Pass Through, set the stereo settings to "light" for compression and "Matrix", etc. nothing helped.

But the hiccups are still random. I will try to feed the box to the TV and the TV to the receiver. It's just odd that if I hook up the box to the TV and listen to the TV speakers that problem doesn't exist.
