I had the same problem with Samsung DVD recorder HR757 and Samsung TV ue40es8005. The DVD is connected with HDMI cable to the TV.
Problem: DVD playback had no sound, HDD TV recordings has no sound.
I got a DVD message telling me "HDMI AUDIO NOT SUPPORTED"
The fix is only via the DVD setup:
1) change Audio output to PCM
2) disable anynet+ (set it to OFF)
It works perfectly now! DVD playback, HDD playback, HDD TV recordings playback. I never get this error message again.
Goodluck
