I am trying to get a fix on this for several weeks since I have this device. Whenever I play a movie or listen to music on SPDIF, no matter what player I use, the sound stops from time to time for half a second or so and gets back.
This doesn't happen on the headphones output so has something to do with SPDIF only (although at first I thought the USB is faulty and changed the USB port countless times).

Possible problems:
- Windows 7 driver
- Receiver decoding Dolby Digital. My receiver is dolby compatible so can decode dolby digital sound whether direct from the player's AC3 or Dolby Digital Live from driver. I also use my tv's SPDIF out and works ok with the receiver, but who knows...
- SPDIF cable....this is almost impossible.

Any other idea?
