I have Samsung UE46ES7000 and after change it to UE46ES7000 i still have posibility to change to line out.
The output level on jack is constant (independend from tv vol).
I have the question - are You create this xls manualy or You have some tool to create it automaticaly? - it could be useful tool for me.
I have found a workaround for line audio output in my ES5500, I guess it is also applicable for ES6xxx series:
After unlocking the Advanced menu, go to Control/Config Options: Change Num of HeadPhone from 1 to 0
After this you have audio both on jack headphone port and TV speaker at the same time. The problem is, that now both levels are controlled together with the remote controller, but you have to set the volume very high (around 50%) to get a good level of line out on the headphone jack. But in this case the TV speakers are way too loud. To sort this out, you can play with the TV speaker amplifier setting:
In Control/Sound menu you can change the Amp Volume to a lower value. For me 0xa0 works pretty well. Changing this value means, that with the same volume level set, the internal speaker volume will be less, but the jack out volume will remain the same. After reboot sound works both on TV speakers and jack port at the same time, and both can be controlled together with the remote!
