Thank you for the reply / suggestion. Unfortunately, I don’t have an AV receiver that I can try. The only receiver I have is my old RX-V690. I have been out of touch for a good 12 years and just now getting back. I was excited to finally retire my rear projection TV and step into the HDTV age with this new Samsung but I have not had a chance to update my old components yet. Or I should say my wallet has not had a chance.
Right now all I have is the TV, a new Blu-ray player and the sound bar. I know the sound bar and TV are fully compatible as this it the Samsung bundle that was being offered. If you buy one of their HDTV’s they were giving you the HW-F450 sound bar for free. This is the 2013 version of the sound bar so it should be 100% compatible with the TV. I believe the TV is the issue. Either buggy firmware, I am on the latest update available 1105, or faulty circuitry in the audio return channel. I came to this conclusion based on how I “think” all this works. Mind you I have been running an RX-V690 for the past 15 years with my 1999 Sony projection TV so I am an old F’er and could be way of base.
I have never experienced sound drops when playing DVDs or Blu-ray’s. The source in this case is the Blu-ray player sending the video / audio byte stream directly to the sound bar. The sound bar then has to process the incoming data stream and send the video bytes to the TV and decode the audio bytes for sound. Because this is working fine suggests to me that the sound bar is working correctly and the sound bar processor / CODEC’s are not having any trouble processing the digital feed. When I use the TV speakers only I have not experienced any sound drops. In this case the video / audio source is the cable box so the TV needs to perform the processing. This byte stream comes in on HDIM port 0 from the cable box and since I have not had any issues here this suggest to me that the cable box and TV processor / CODEC’s via HDMI port 0 are working fine. So image / sound data coming from cable box to TV and from Blu-ray through sound bar to TV all work fine. This leaves the audio return channel, HDMI port 2, and whatever processing or circuitry is used here along with the HDMI out port on the sound bar.
When the sound has dropped the control commands still work, e.g. control commands as in volume up / down, mute, connect / disconnect Anynet, etc. I believe the control commands use a different pin, wire, in the HDMI cable then the audio stream so this suggests to me that the sound bar and TV are still in sync leaving only the audio return channel in question. Finally, I replaced the original sound bar with another brand new HW-F450 and the problem remains. I also tried different HDMI cables and still the problem remains. One note to make is that all the HDMI cables I have tried are 1.4a spec having Ethernet, but that should not matter.
Since I have tried 2 brand new HW-F450 sounds bars, changed HDMI cables, tried TV speakers only to isolate the cable box and only when sound is being sent via the audio return channel does this problem occur it must be the TV. Right? (please someone tell me if I am a complete fool in my logic here)
Once you setup your system I would be very curious to hear if you experience any drop outs using the HDMI arc port through a true receiver.
