Question: How does the HDMI in/out work on this? Can you hook the source with HDMI into the soundbar (for audio), and then pass video through to the TV?
Document: Works great, but the optical audio output is dead. Since my TV only has 2 HDMI ports (both being used), I had to resort to using the stereo audio output. Still works fine enough for my needs, but a little disappointed. That's what I get for getting a refurb.
This goes along with my recently purchased 50&#34; TV. Still in the process of installing but seems to work fine.
Makes a huge difference in the sound from my 75&#34; Samsung LED TV, but it was kind of unclear the best way to hook it up and still have just one remote to operate the TV, sound bar, and DirecTV receiver. As it is, we still use the sound bar remote to adjust the volume..
5,000.00 worth of sound for 170.00 I am still trying to pick pieces of ceiling out of my hair from having my head blown off. I gotta get a new TV to go with my Samsung soundbar.
I purchased this soundbar to use as a replacement for the speakers on my Samsung TV. A fancy surround sound setup really doesn't appeal to me; we mostly watch TV shows (comedies and a few dramas) that don't require much sound immersion.
I bought the Samsung subwoofer to ensure compatibility and easy set-up with my new Samsung LED 55&#34; Smart TV. So far regretting both Samsung products! Samsung soundbar not recognized by Samsung TV automated set-up tools! So, have to manually set-up - a very painful process. Further, Samung subwoofer that came with the Samsung soundbar is not recognized by the Samsung soundbar!
When turning on my PS3, the sound bar changes on its own from HDMI to Digital In. I have to cycle through and select HDMI again.
Very easy to hook up, no scuffs or anything. Works as promised at this point. Our living room in our new place is set up a little different, and its a rental, so I didnt want to hassle with wires and putting all the speakers in. This is getting the job done.
The problem with those is they only had red and white cables no hdmi or optical. The samsung soundbar lets u use it for all your devices.

Answer: Yes you can,  it is an auto action if your sound bar is Samsung,  and your TV is also.  But if not just hook up to your HDMI in on the TV and HDMI out on your sound bar.  Or just as easy HDMI 1 or 2,  to HDMI 1 or 2 on each device.
