I'm having the same issue.
I have wireless surround headphones with a transmitter which works like an hdmi hub (sony mdr-hw700ds) .
In order to use as few cables as possible, my blu-ray player and a modem with tv service are plugged into the transmitter using hdmi inputs and the hdmi output of the transmitter is plugged into the hdmi input of the soundbar.
Then the hdmi output of the soundbar is plugged into a videoprojector.
The aim is to either use the soundbar as the main speaker when watching movies or the headphones when someone sleeps in the bedroom next to the living room.
When using the soundbar, everything is fine as the transmitter can work in passthrough mode even in standby.
My problem is when I use the headphones, it seems that only the video signal is sent to the soundbar, as the audio signal is sent to the headphones only (apparently).
Meaning that after 15 minutes the soundbar automatically switches off and the video signal received by the projector is lost.
As a consequence, every 15 minutes I have to power on again the soundbar in order to retrieve the video signal, which is really really annoying!
If only the soundbar could work as my headphones transmitter, so even in standby mode the signal could still pass through it...
So please samsung techs, release a firmware update to remove this time limitation or allow signal transmission in standby mode, I want to watch a movie longer than 15 minutes!!!
I'm at my wit's end with this thing. Every single time I want to watch TV, I need to enter the setup to switch back to the sound bar.
Unless I can find a quick fix, my next tv and sound bar won't be a Samsung. Why even bother with help apps and community boards when you clearly don't monitor them and monitor customers with deal-breaking defects?
excuse my english. i got the same problem with digital cable connected to my tv.
i finaly solved the problem by setting the Audio format (it's a samsung tv) my output tv to PCM instead of Binary train (free traduction...). Hope it will help.
This is so ridiculous. I have the Apple TV 4k connected via HDMI to MS650 connected again via HDMI to the Samsung KS8000 TV. And after 15 minutes the thing turns off. Why on earth is this the case??? I never ever want it to turn off. Just leave it on!
Nope, made the setting change. It didn’t help. Samsung- would you please look into this? All we want is the option to actually disable the auto-off. It’s supposed to exist, but choosing to disable it doesn’t work. In our minds, that’s a bug that needs addressing in a firmware update.
Do this 2 things if you want to stop auto power down:
- Auto Power Down function, while in “AUX” mode, press and hold the play/pause button for 5 seconds. “ON - AUTO POWER DOWN” / “OFF - AUTO POWER DOWN” appears on the display.
- Activate the tv HDMI-CEC ( SIMPLINK for LG, Anynet for Samsung) and HDMI Auto Power Sync
After I performed this two settings my soundbar (HW-K950) stays open.
I Have The Auto Power Down In AUX Mode Set To OFF (OFF - Auto Power Down Scrolls When Play/Pause Button Is Held Down), The HDMI-CEC Anynet+ Is Turned On In TV Settings, And The HDMI Auto Power Sync/Auto Power Link Is Turned On (Auto Power Link On Scrolls After Holding Down Left On The Circle Pad) I've Read It Doesent Work If HDMI-CEC Anynet+ Is Enabled?. It Still (MS650) Turns Off After 5 Mins With No Sound With HDMI ARC Connection Usually When Watching Netflix Through The Netflix Smart App On The TV When Paused Or On Menu With No Sound. It Does Not Do This Using The Wi-Fi Connection It Stays Turned On At All Times. Am I Missing Something With The Settings? I Have Read There Is No Fix For This. Thanks.
