Hi Scott,

I'm not too sure, but I'll see if I can find some suggestions for you.

Thanks,

Hello @Scottmc1980,

if anything the optical comes out of your TV and goes to the soundbar (at least in terms of which way the signal flows).

Did you check which audio format your TV outputs its signal?

Hi there is an option on the headphone setting in SOUND menu to select sub . You could try selecting pcm just to see if you get stereo. Not sure if optical cables give surround sound. You might have to use the hdmi arc port for that

Optical cables do pass surround sound, and the MT-300 does not have an HDMI connection, so this is the only way of getting surround to it.

However, it is only a 2.1 soundbar, so any surround effect will rely on the audio processing within the soundbar to give a psychoacoustic surround experience from the two speakers -

the S-Force PRO Front Surround which Sony tell us ‘reproduces a virtual surround acoustic field for immersive, cinematic, powerful sound of stirring depth and clarity’.

Connecting the soundbar vía the headphone socket set to sub will make it operate in 0.1 mode - not quite what is wanted.

The soundbar audio is Dolby Digital True HD; it’s worth looking at the sound options for Optical Out on the TV to see if this is covered, but if not, your suggestion of PCM may very well do the trick.

@Scottmc1980, if still no sound out, have a dig for the Optical Out Settings in the audio menu.

On my Android set, these were turned down to a whisper, and wanted raising significantly.

There is also a setting in there to choose between fixed volume output to the soundbar, so you would have to control this with the soundbar remote, or variable, so you can control it with the TV remote.

I greatly preferred the latter, in the absence of the CEC/BraviaSync sound control possible over HDMI with those soundbars that actually have HDMI, which this one doesn’t.
