Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.

Sorry to hear you’re having trouble.

Can you tell me how everything is connected?

What is the model of the soundbar?

Customer: replied 11 months ago.
Model of soundbar is IT153Bv821-03
All is connected through the cable box, HDMI
Expert:  Nathan replied 11 months ago.

So when you try to watch apps from the tv, you only get buzzing, the audio isn't still playing from the cable box, correct?

Customer: replied 11 months ago.
No, the audio is still playing , how do I play from the TV bypassing the cable box?
Expert:  Nathan replied 11 months ago.

Can you please recheck that soundbar model and tell me the brand as well?

Customer: replied 11 months ago.
Brand is iLIVE.
Expert:  Nathan replied 11 months ago.

Okay that is a very basic/generic product. The hdmi port on it is an output only, this type of soundbar does not support hdmi ARC (audio return channel), so it will not work with your tv apps via hdmi only. That only serves to pass video from the box to the tv. You'd need an extra connection here, meaning an optical cable from the tv back to the soundbar (then set the soundbar to the optical input mode): http://amzn.to/1Z6fNsK

The soundbar is connected to the TV set at optical input.
Expert:  Nathan replied 11 months ago.

You mentioned only hdmi before.

Change the soundbar input so it is at optical,

then go into the tv setup menu and change the audio output format to pcm/stereo.

You may need to do so in the individual apps as well.

This Smart TV is very SMART! (smile) It is beyond pcm/stereo. The settings require more info.
I have to go before we fix this, I will call again.
bye Marylee

What specific info do you need? You're looking for pcm/mtc/2ch/stereo (basically anything but dolby/digital/surround).
