Make sure the sound is turned up on your external audio device. I got here because I was expecting the built-in sound to cut off when it accessed the external device but that is not how these work.

PCM mode is a digital audio file that should be sent to the soundbar via an optical or coaxial digital audio cable. The coaxial digital audio cable uses an RCA plug but not the L/R stereo channels of analog audio. The aux input is usually the 3.5 MM cable from a computer, CD or MP3 player or a cell phone or tablet.

First, which type of RCA cable is connected between the sound bar and the TV? Second, are you sure that the TV connection is an audio out? (A number of recent TVs have only one audio output. This means there is only the optical audio out and not even a headphone jack.)

Once you double-check the input at the sound bar, choose the Line In input if you are using the stereo RCA cable. If you are using the Optical input, select that input. Use either the Mode button or the specific input button on the remote. Then double-check that the TV is set for the appropriate audio out.

I hope this helps. Please add a comment with the model of the TV and the sound bar for further information. I looked at the ONB18SB001 documentation for some of this. The manual for this Onn soundbar is available at Manuals Lib. See https://www.manualslib.com/manual/1498038/Onn-Onb18sb001.html?page=12#manual for the list of input modes and the input to which they correspond. Here is the image of the inputs on the back of the ONB18SB001: https://www.manualslib.com/manual/1498038/Onn-Onb18sb001.html?page=7#manual .

TV is ONA43UB19E04, soundbar is ONA19SB002, Cable is 3.5mm at soundbar, RCA at TV in marked audio sockets. Would an optical cable solve my problem?
Cindy Wells Sep 05, 2019

The ONA43UB19E04 has a 3.5mm headphone jack and a digital optical audio out. You'll need either an Aux cable (3.5mm M/M) or a digital optical audio cable. The digital optical audio cable is a fiber-optic cable. The cable will ship with covers on the ends that you remove before attempting to insert the cable in the devices. The ONA19SB002 is slightly different from the ONA18SB001 that I referenced; the lack of the Line In makes a difference. The RCA audio on the TV is an audio input for the component video. The specs, including the connections, for your TV and sound bar are on their respective pages at Walmart. Seehttps://www.walmart.com/ip/ONN-43-Class-... for the TV's specs. The soundbar specifications are here:https://www.walmart.com/ip/Onn-2-0-Wirel... . I hope this helps. Cindy Wells

I bought an optical cable and plugged that in. Still no sound from the silencebar. Am I looking at a defect in the TV?
Cindy Wells Sep 06, 2019

Some TVs need the digital audio output enabled. Check in Settings > Audio to start. On one of my TVs, the TV audio had to be turned off before the external speakers (digital audio output) were enabled. If the TV indicates that the digital audio output is active, then there may be a defect in the TV or the cable. Unfortunately, I can't find a manual for the ONA43UB19E04 online and I don't have that model myself. So I can't positively determine where in the settings to look for the option.

(Note: The headphone jack usually becomes active automatically when the AUX cable is connected.)

Hi probably a silly comment - have you connected to the AV in or Out sockets on the TV? Worth checking? also do you need to select an audio profile on your TV in order to divert from the internal speakers. Worth looking at your sound preferences on your TV

SOURCE: The sound on our soundbar keeps going off and on, intermittently. The soundbar is an Alba 2.0 soundbar SR-30 with bluetooth 50w bought from Argos, had 3 replacements now - all faulty. Thanks.

Check the speaker/s. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis. If you wish to get some details; check the site linked here. Pull up older posts.

I have just bought a samsung soundbar hw h355 and I'm trying to connect it up to my toshiba tv, via the aux cable but I get no sound from it via the tv link. I works when I link my phone up via Bluetooth....

Please get a optical cable and run it from TV to soundbar for best sound. If you are using aux input on sound bar that will work but it is analog sound. TV needs to have mini audio out or red/white output on it maybe labeled audio out

I have a Sharp Aquos LC-60LE640X TV and I am trying to connect a Samsung HW-H751 Soundbar to it. I have hooked up the optical cable, adaptor and sub woofer, I have tested the Bluetooth function throug

If you are connecting the soundbar to your TV with the digital audio cable, make sure to select "D IN" using the source button on the soundbar. Bluetooth (BT) is a separate source from another device. (phone, etc.) The TV will need to be set to use the digital audio output and probably PCM format. (?) The subwoofer is preconfigured at the factory to mate up with your soundbar. (See below instructions - your soundbar includes the amplifier:)

Digital audio output setting:
After connecting an amplifier with digital audio input and
external speakers as shown, you should set an audio
output format compatible with the programme you are
watching or the device connected.
Go to "HOME" > "TV Menu" > "Setup" > "Option" >
"Terminal setting" > "Digital audio output" > select
"PCM" or "Bitstream".
NOTE
• When set to "Bitstream", Dolby Digital is output when the Dolby
Digital or Dolby Digital Plus audio formats are received. When
set to "PCM", PCM is output no matter what audio formats are
received.
• When set to "Bitstream", HE-AAC audio formats can be output
as Dolby Digital.

I have a Philips soundbar that I have hooked up to my flat screen tv using audio (red,white) cables directly from soundbar to tv and there is no sound coming out.

Be sure you are hooking up the Audio Output from the TV or satellite to the soundbar.

From the satellite box both Audio Output and Video Output go to the TV, and then Audio Output from the TV goes to the soundbar.
Or
From the satellite box Video Output goes to the TV and Audio Output goes to the soundbar.

Does the Samsung UN50f6300af smart led tv support the Samsung Wireless audio soundbar HW-H450?

Because your TV is not Bluetooth-enabled and you are trying to connect it to a Bluetooth-enabled soundbar via Bluetooth. There are other ways to connect your TV to the soundbar:

1. analog AUDIO OUT (L/R) of your TV to the AUX IN on the soundbar (use a 3.5 mm.-to-RCA audio cable).
2. Optical OUT on your TV to Optical IN on the soundbar.
3. HDMI port to HDMI port (this may not work if your TV is not ARC compliant you have to try).

You get better sound quality with option 2.or 3. (if this one works for your TV)

Here is the link to download the soundbar's User Manual for help with the connections:

Do i need to buy anything extra for my ilive 37' soundbar for my tv? The sound doesnt work with my tv, but the bluetooth works just fine.

You'll need some sort of audio cable to connect the TV's sound or audio output to the soundbar. For the most basic connection, use an RCA-style cable ( like the one found here: http://goo.gl/5F8yLh ) to connect your TV's audio output to the soundbar's input. Most soundbars also have an SPDIF input ( like the one found here: http://goo.gl/2F2rKs ) and most modern TV's have an SPDIF output. Get an SPDIF optical digital audio cable to connect the two devices together. Once you've decided which type of connection to use and have connected the TV's audio output the soundbar, then make sure you select the proper input on the soundbar. That should fix your problem.

Just purchased a Goodman 50 w sound bar connected to AUX on tv and sound bar clicked AUX on remote white light shows no sound just a loud buzz

To the best of my understanding an Aux port is usually an input port. So you might be sticking the sound bar terminals into the wrong connector in TV. The audio signal from the TV is meant to go into the Aux In port of the sound bar. Usually this will mean a pair of RCA cables (white and red) from TV out to Aux In. If you have done the right things then maybe check if soundbar is not in mute. Try some other source as well. Like connecting an iPhone or ipod stereo out to the Line In port in soundbar and selecting LineIn mode.
see page 7 in the soundbar manual. It is hard to know what TV connection you are using. Is it selected on the TV settings? http://www.goodmans.co.uk/support/downloads/user-guides/GDSB02BT20-ib.pdf

Connecting an LG soundbar to non optical digital tv

I'm pretty sure your soundbar has more than 1 input. Check your manual. There probably is AUX input on soundbar and that will allow you to connect to TV, assuming that your TV has any audio out. It could be either white and red RCA connectors or headphone jack.
