Is anyone else having issues with the “Sound Mode” settings changing after you turn off the tv? Seems to have been introduced with the new software update. I use Cinema mode which outputs DD sound as intended through my 5.1 home cinema, but since the new tv software update the sound output changes to Multi Channel with dialogue being output through all speakers (although Cinema is still selected). Every time I turn on the tv I have to deselect and reselect Cinema mode to resolve the issue. No other changes to my setup. Just the recent tv software update.
