Unfortunately, I am really very disappointed with the product because it does not work when one of the cable is longer than 30 cm. Thus, this product is unusable. But what goes well, would be a toslink coax adapter and then use a coax Y-cable and thus can be the the split. Have therefore my Sonos always tripled but work on this product, I have thrown away because a return is too expensive.
pity Amazon should accept such product fakes from the sales list
