Sound Bar

MJ 02 120 36 December 30, 2015 at 01:07 PM
I recently got a sound bar and tried to hook it up to my tv via digital optical audio cable. I go into the TV settings to change my audio source, but it won't let me select PCM.

Does anyone know why it's not giving me the option to switch sources?

When I plug it in via the optical audio, a terrible repeated static noise emits from the sound bar. The same thing happened when I tried it w/ the aux cable. I connected my phone via bluetooth, and it sounded pretty good, so I can't figure out if the bar, the TV, or the cable is bad.

Please help!

Please start by telling us the model of the TV and Sound bars you have. Also make sure the end caps are off your optical cable. They are really easy to leave on.

It should be as simple as connecting the Digital audio cable to the TV and sound bar, turning on the sound bar and setting the TV speakers to external on the TV menu. You should not need to change the audio source for the TV as that remains I assume your HDMI connection from your STB or audio visual receiver. It is most likely not showing the option to switch the source because you do not have any other source connected as such.

Sorry, I didn't have this info earlier!

TV: Toshiba 32AV500U
Soundbar: Insignia NS-SB314

I did take off those little caps; the wire seems to go in just fine.

Sorry, I don't think I explained it correctly. I didn't try to change the source, but the audio output. I tried to change from internal speakers to external, but my TV won't give me the option. I attached a picture that shows that the PCM option is greyed out. Doesn't make sense!

grayed out could mean selected. There are plenty of tv's that can only output PCM audio (or only support other options when the tv's internal tuner is the source).

Do you have cable? If so, you need to connect the sound bar to the FIOS or Cable box.

Are there only "On" and "Off" settings in speaker?

Procedure
With the TV’s power off, make sure that the optical cable is securely inserted in both your TV and audio receiver.

After completing the previous step, turn your TV on using the power button.

Once the TV is fully powered on, press the MENU button, on the remote control.

Once in the menu, use the left or right arrow to open the audio menu.

Next we will use the UP or DOWN arrows to highlight Audio Setup, as illustrated in the previous picture and press “ENTER”. Once again, using the UP or DOWN arrows, we will need to select Optical Output Format and then use the LEFT or RIGHT arrow keys to select Dolby Digital or PCM.

After completing this we will use the DOWN arrow key to highlight DONE. If when you arrow down it highlights Reset simply press the RIGHT arrow key and highlight DONE. After DONE is highlighted please press the “Enter” button to save your settings.

You need to go to the TV/Ant setting to change the optical out format. I have a Vizio TV that's like this. The setting should carry over to the other inputs. Info is on p28 of the manual. Then just make sure that your soundbar is set to optical input as opposed to the other options.

Enjoy the new soundbar!

You don't have to, but it generally improves things.

I do have cable, but if I connect the sound bar to the cable box, then it won't work with other sources right?

Thanks for the info. I tried it just as you said, starting with the tv off, and no luck. It still won't let me select PCM and a static-y noise comes from the speaker.

I'm at a loss! Confused

Do some basic tests:
1. connect the optical cable to the cable box (hopefully it has optical out) or directly to a cd/dvd player. If you still get static it's the cable or the soundbar, if the static stops it's the tv and you have to try to figure out if it's a setting or if it just doesn't work right. If it's intermittent it's probably the cable.
2. try a different optical cable

The PCM line is grayed out in your picture because the next line in the menu "Speakers" is selected. I suggest you give the TV's manual a read: http://cdgenp01.csd.toshiba.com/c...u_om_e.pdf

The only digital output options are pcm and dolby digital... pcm is selected. your soundbar only works with a pcm input.
