New DVR broke Soundbar connection to TV

Jun 5, 2015 12:57PM PDT

My new Samsung TV and new Soundbar have been working perfectly using the TV ARC connection for 8 months. But a few days ago when I swapped an older DVR from the cable company for a new enhanced DVR, suddenly I have no sound at all. The cable company's technician was able to get the Soundbar to work, but ever since I turned off everything that night the Soundbar won't connect with the TV. I've tried calling the cable company and Samsung, but they haven't been able to help me. Does anyone have any idea what I can do to fix this? I have not changed anything about the cable hookups; I only swapped out the HDMI cable and the coaxial cable from the back of the old DVR to the back of the new DVR. The DVR works and the video on the TV works, but there is no sound on the TV.

Samsung TV Model # UN46EH5300F
Samsung Soundbar # HW-H450
Samsung Blu-ray Disc Player # BD-E5900
Arris DVR # DCX3600-M

All hookups are via HDMI cables. TV & Soundbar are wall mounted.
Troubleshooting I've tried:
When I first paired the TV and Soundbar, I had to turn off the TV speakers (or else both Soundbar & TV speakers were on). Since then I have had to turn on the TV and the Soundbar separately, but mute, volume, and power OFF worked with just the TV remote. I was even able to pair the (old) DVR remote to work mute and volume after turning on TV and Soundbar.
In trying to troubleshoot, I tried to find the TV menu for turning back on the TV speakers but Speaker Settings was grayed out (not clickable) on the TV Menu. (I thought if I turned back on the TV speakers then something might 'reset' and I could start over with pairing the Soundbar to the TV.)

I tried turning off the TV and the Soundbar, then disconnecting the HDMI cable between them. Then I reconnected the HDMI cable to the Soundbar 'HDMI OUT' port and to the TV 'HDMI IN' (ARC) port. I set the Source on the Soundbar to 'D. IN' and then pressed the 'Anynet button on the Soundbar remote to toggle the Anynet function to ON. I was following the instructions here, but still have no sound.
When turned on now, the Soundbar displays 'D. IN' but never connects with the TV. When I look on the TV Menu under Anynet Devices, only the Blu-ray Disc Player is shown. When I click on 'Refresh' under Anynet Devices, it does not find the Soundbar.
I appreciate your help!

Jun 5, 2015 update for TV.
Jun 5, 2015 11:22PM PDT

While I would try the connections like this:

BD player -> HDMI in to soundbard, HDMI out -> HDTV ARC PORT

I see an update dates Jun 5, 2015 at

ASK SAMSUNG to walk you through this update. I don't do that for reasons such as I can't take responsibility over what it does or the end result. Samsung owns that area.

So my advice is the update and maybe a change in hookup. I've found ARC to be hit and miss.

Samsung TV Firmware Upgrade

Where did you see the date of the update? When I unzipped the compressed file to a USB drive, the file dates were all 3/9/2015.

On their web page.

The file date is older since it takes them time to test, committee meetings and then put on the web.

"Upgrade File(USB type) (Firmware) ver.2004.0 - All OS (EN, 141.38 MB) ?
Jun 5, 2015 "

I don't mind questions but to save this question I shared the link where I found it.

Your DVR is to blame

This isn't a problem with your soundbar, it is 100% a problem with your DVR. I just got TWC, and I am experiencing the same thing. In fact, there are multiple threads about it. See here:

and there's even talk of a Class Action Lawsuit due to that, and other bugs:
