Title: Many problems with optical output, Poor customer support
Review: I use it to connect my PC to a receiver via the optical link, but I find the mute button, the volume control, the headphone all stop working. The PC flashes the message "invalid speaker configuration".I then called the customer support. The guy had no clue, keeping saying "maybe", "yes", "possible"... In the end, he concluded it was supposed to work that way (of malfunction).
Is the review positive or negative?
