Once I received 1455, the TV switched back to internal speakers. When it does this, the volume and mute icons change slightly. I change it back to Receiver and it stays that way for a while. A day or two later I find it has switched back to Internal. I usually discover this after turning on the set. Then sometimes the AVR does not power up, but it usually does. But the Volume and Mute functions only affect the TV speakers, not the AVR. The AVR displays as if it is receiving an HDMI signal ('Dolby' if that is what is being received at the time) but no sound (usually). Switching the TV back to 'Receiver' makes it normal.
Anybody else see this kind of stuff?
Yes, sadly I have seen very erratic operation using HDMI/CEC/ARC for sound, and things have deteriorated with firmware 1455. I connected a Vizio SB4051-C0 to my JS8500 back in November. I'm pleased with the sound out of this unit, but getting this thing to behave with the JS8500 has been problematic and things have gotten worse with the 1455 firmware release. Prior to this release, the sound bar would power up/off with the TV about 95% of the time. Since the new firmware, I have a new problems I had not seen before.
-Each morning doing the work week, the TV powers on at 6:30AM using the TV scheduler. Sound comes on for a few seconds and then goes off. The sound bar LED's indicate the sound bar is muted. Using the Samsung remote, it unmutes successfully. This occurs about 50% of the time.
-TV powers up with both sound bar and internal audio. The speaker selection display indicates internal audio is selected. I would guess this issue is in Samsung's court, as they control what ports get the audio, and both is not a legit option.
Other problems I've had with this as well as other firmware releases, but occurring more frequently with the 1455 release are:
-Sound bar does not power up with TV
-Sound bar does not power down with TV
-Intermittent audio dropouts
I know others would recommend connecting the sound bar via optical, but I specifically chose the Vizio for HDMI connectivity so the wife could use just one remote.
Who's to blame for this? Vizio or Samsung? I suspect both or maybe the HDMI/CEC/ARC specs leave too much up to the vendor. Mixing vendors is not without risk.
I have connected the sound bar to another Samsung TV (32H5500), but not long enough to determine consistent operation. Frankly, I liked the earlier model for displaying a numeric sound level for the sound bar as well as titling it "SB4051" instead of just "Receiver". The JS8500 lacks this feature despite costing considerably more. Perhaps it is also evidence that the JS8500 HDMI/CEC/ARC controls have diverged from prior models, and not for the better.
I should also point out I have the Samsung Instant On feature turned off, as it seemed to be the root of many unexplained problems (Picture size changes, source menu stuck on screen).
Yes, the picture is very nice on this set, but frankly, the control functions on this model aren't so great. I've been a long time Sony fan and never had to deal with the kind of issues I'm having on the Samsung. The Sony's just worked.
