I recently bought a Samsung UE55M5512AKXXH HDTV. I previously had a Samsung UE47F6200 HDTV.
With the older TV, the sound was set to the optical audio output with PCM. The optical cable was then connected to a small digital-to-analog converter, which in turn was connected via standard RCA cable to the input of an analog receiver. On the imput side, in addition to live TV, I used an nVidia Shield connected to the TV viad HDMI dable. I did not have any problems with this setup.
Now, fast forward to a few weeks ago when I got the new TV. Old TV is removed. New TV is dropped in to the existing system. Everything else is exactly the same. nVidia Shield connected to TV via HDMI on the input side and optical audio output using PCM to the DAC, then analog audio from the DAC to the receiver.
Now, with this new TV installed, I'm experiencing audio dropouts, but only on content from the Shield - Netflix and Amazon streaming, local video files and even audio / music files. Live TV does not produce any dropouts, and so at first I could have something to do with the HDMI link between the Shield and the TV, maybe some HDCP handshake issue. But then I tried listening to the audio through the TV speakers, and there were no dropouts, even with input from the Shield.
And so now I'm wondering if there is some incompatibility between the TV and the DAC. But again, this all worked before - the nVidia Shield with optical audio to the DAC - with the old TV. And at the same time, the optical audio is OK with live TV. It's just with the Shield that I have this problem.
The only thing that has changed is the TV.
This does not make sense to me. Does anyone else have any ideas?
