Sound interupts HD (via CI+CAM) via TOSLINK Connection Yamaha AV740
i do get sound interrupts when not using the internal speakers. Connection is via an optical TOSLINK cable to a Yamaha AV740RDS AV-Receiver. It only occurs when displaying encrypted channels via an ASTRA CI+ CAM. Inbound TV Signal is from a Satellite Dish. Any ideas on how to fix it?
TV is a 42PFL7656K/02 with latest firmware 000.014.100.00
The interrupts seem to be less frequent after the Set has just been switched on. Once channels have been switched back and forth they appear very frequent - esp. on channels VOX-HD and Kabel1-HD.
The sound interrupts also seem to be significantly less frequent when the Ethernet cable (connected to a local TP-LINK 1043ND Access/Point Switch, connected to the main gigabit hub) is disconnected.
Easylink is disabled, TV Speakers switched off.
