I have ordered the adapter times at random, as was described in other reviews, both positive and negative experiences. I first tested the product with a 10m cable from Thomann and a 1m cable of Oehlbach, but to no avail. However, I had at the same time still 2 Toslink cable by Wentronic (Wentronic toslink to toslink) 2.2 mm, ordered 1 m). Combined with the Oehlbach cable Splitter fulfilled absolutely its purpose. It must always be turned on only one of these devices, otherwise none of the signals is detected.
So for me working combination: - Cable: Wentronic 1m & 2m + 1m Oehlbach Toslink cable - Xbox 360 - Panasonic BDP7500-MKII BluRay players - Yamaha RX-V440 RDS AV Receiver
