I have a QN65Q70RAFXZA with 4 HDMI inputs connected. Also have a Q80R sound bar.
The latest TV update has caused issues with the communcation between TV and the sound bar.
When the BlueTooth is working there are audio dropouts, about 300-500mSec, every 10 to 120 seconds.
First question, why can you combine optical for the data, and BlueTooth for control? It would solve a lot issues.
Secondarily, before the drop out issues started, there was often a 20-100mSec audio lag between audio and video.
Samsung, a bit more flexibility and accuracy in your firmware would be appreciated.
