I Have the 46 UE46ES5505 Samsung Smart tv with 1021 firmware.
Problem is that I have external loud speaker and it all worked fine for few weeks
Now suddenly if waiting 10-20 mins it just loose signal to the loud speaker.
When if i go in the menu and click up and down it works again..
I tried the loud speaker on a PC and no problems what soever.
So it is like the samsung tv loose the signal?
Don't wire your sound through your tv?
It happens after new 10.21 firmware and exactly after 30 mins..
I even called the samsung support, poor service..
they just keep saying use a samsung external speaker and trying to say my device is not compatible even it worked for few weeks before upgrade.
Then I ask if I can downgrade and they say no.
