There is 32PFL7685H/12 with FW v0.140.47.0.
Seems that ALC ( dolby or smth) working bad during playback of any mkv, avi files from USB flash. Sound loudness is floating down especially when women speaking. Is it possible to switch off or resolve? Sound is OK during playing at PC.
Another problem is that http://www.ivi.ru/ at NET TV become almost unusable. Earlier there were many playable movies. Now after pushing PLAY appears: This video is not available for your platform even for movies played without notifications earlier.

Thanks,
Vlad.
