My sound bar doesn't emit sound. I have a Vizio model SB3630-E6 sound bar. It is connected via HDMI cable to a Portta 3 port switch. What do I need to do/change to have the sound bar work?

Your sound bar can be connected to the UA40C500QF. Get an appropriate audio cable based on the sound bar. You'll either need a optical digital audio cable or an analog audio cable with a 3.5 mm plug on at least one side. (If your sound bar has an AUX input, then a 3.5 mm to 3.5 mm M/M audio cable is appropriate. Otherwise, you may need an RCA (M/M) to 3.5 mm audio cable or some sort of RCA to 3.5 mm adapter (F on one side, M on the other).) Connect this cable to the audio out on the TV (headphone or digital audio) and the appropriate audio in on the sound bar.

Set the sound bar source to the chosen input (Aux or Digital In (D.In on some systems). Next, set the TV to use External speakers. This is in the Audio sub-menu. The volume will now be controlled by the sound bar volume control.

You can still use the HDMI cable (HDMI out to any HDMI in on the TV) if you want to use the TV screen when changing the settings on the sound bar. Just change the TV source to that HDMI port with the Source button on the TV remote or on the TV (the left-most button on the front panel). Then change your source back to the video signal for the TV to view items connected to the other HDMI ports. If your sound bar has an HDMI input, you would similarly use set the TV to the sound input to watch that source.

I hope this helps. See the manual for the UA40C500Q for the details on setting the speakers to External speakers. The manual is available on the support page: https://www.samsung.com/au/support/model/UA40C5000QFXXY/ .

Optical leads have a red light that shows even when unplugged. If that is not on the socket is switched off.

Hello. Your Mitsubishi doesn't support HDMI ARC (Audio Receiver Channel). You will have to use the AVR or the Digital Audio output to connect your sound bar. Sorry.

If you have newer models with HDMI, just plug from sound bar HDMI port to TV HDMI via HDMI cable.

I suspect that the TV you have does not support the ARC function that the sound bar has. What you may have to do is use the Optical In from the sound bar to the TV and you should be good to go. You may have to change the TV's settings to use the Optical In though. So you should end up with the BluRay Player connected to the TV via an HDMI cable, the sound bar connected to the TV via the Optical In using a fiber optic cable. Hope this helps.

the details you provided were very vague, however from my experience when a device is connected to another device via and audio capable hdmi cable, that device renders it audio output to the device its connected to and normally turn off all other audio outputs beside optical- I would assume there is an option in the blue ray player to turn off hdmi audio, which will in turn activate other audio outputs- you may also look for audio out port on your tv, it is ideal to connect the sound bar directly to the tv set audio out ports. To sum this up,
if you plan to use your player via hdmi cable you need to turn off hdmi audio output on the blue ray player and the plug an audio cable from your blue-ray player to your sound bar
you may also as i said connect your sound bar directly to your tv, the issue is most tv sets now a days do not have an audio out port, if you do then everything you play thru your tv will have audio via sound bar
there are several way to go here but unless your sound bar has hdmi av switching capabilities (im sure not) this is one of the most simple--Good Luck.

Try connecting a optical audio cable out from your TV to your sound bar and directly connect your 722 to your TV with HDMI.

HDMI has both Audio and Video (High Definition Multimedia Interface) and should carry both. However, I had this problem with a client just the other day and it turned out that the firmware on his TV needed to be up[graded. Different model TV, but I believe you may need to download the latest software/firmware update via your PC and put it on a flash drive and then flash the firmware on your TV to get it to work. Sorry I don't have the specifics; I was stumped and the Time-Warner guy ended up doing it. I hope this at least sends you in the right direction.

I would venture a guess that the HDMI cable itself is damaged. Try using a different cable.
