please check the audio coaxial cable if all tightened well
please check the ST fiber if inserted well
this issue happens often when the ST end face is dirty
For long range application, please check the fiber transfer link-budget, if it is too long, the received optical signal is very weak, and may be out of receiver reclocker capacity and fail to recover the useful signals
