Grumpy

For info after last post. There is nothing else connected to soundbar. Only the tv..

When it displays ARC on the soundbar there is no sound. Scroll through the remote and the tv sound comes on in USB display, Bluetooth display, then get no sound when  HDMI/optical/ARC is displayed. Pull out soundbar plug, it re boots again and works fine.

I think it may the BT YouView set top box that is the problem, so have decided to switch to latest sky q box.  Also,  If I just switch off the soundbar at the wall and take plug out, the soundbar re boots and works ok, if I leave the tv and bt box switched on.

its very frustrating...

Oled55C9 tv and SL9YG soundbar connected via ARC HDMI. Works great. Switch on tv in morning and no tv sound through bar. Have to disconnect all tv/soundbar/btbox from mains elec and restart including BT YouView box startup (takes ages) and sound works ok again.

Changed soundbar and cables, checked all settings on tv. Absolutely delighted with tv and soundbar (when it works)

Any suggestions for a fix?
