5.1 sound problem

[CatalinStefanel]

Hello,

KDL-50W755C - Firmware PKG3.179.0100EUA

Samsung HT-J5150 5.1 Home Theatre System - Connected via HDMI 4/ARC

I'm having sound problems after new firmware update. It did not happen using the original firmware. The sound on the HT simply stops randomly. To make it work again I have to set ON TV sound and then re-activate sound on HT. 

Sometimes it feels like it's buffering .. sound off/on .. like it's trying to sync out the sound. It mostly happens while watching TV (direct cable, no setobox or anything).

Tried TV factory reset and HT factory reset. It doesn't fix the problem.

Is there a known  problem ? Saw a few topic while on optic cable but nothing for hdmi.

Thanks.

Hi, I have the same problem when audio is going through HDMI cable connected to Yamaha home cinema receiver but I have audio without on/off when I am using optic cable connected to receiver.
