Why does 5.1 audio have a large gap?
Further, the receiver may lose "synchronization" not knowing what is the start or the end of the frame. As a result of these factors, you hear a larger gap in audio when compressed 5.1 streams are transmitted and data loss occurs even though it is not taxing the link as much. In the case of playing uncompressed CD the lost data only impacts the specific audio samples and not the adjacent bits so the audible gap may be much smaller.
How to test if a toslink is working?
The first test for Toslink is to pull the receiving end out of the AVR and see if there is a bright red light coming out of the end. Shine it on your hand and look for a brilliant red dot. If you have one and the ends are reasonably tightly held by the sockets at each end then it is probably OK.
