Sony TV sound output

[Easternlight]

I'm struggling to get the sound from the TV out to my hi-fi.
I'm using an optical out and it works fine when using the internal digital tuner or when playing dvds via a dvd player on an HDMI lead.
The sound comes out of the TV and the hi-fi.
But if I play back recordings from the same dvd player which is also a hard drive recorder there's no audio out on the optical out.
Also if I playback media from the USB input again no output on optical out.
I've tried every setting I can find for sound TV/ Audio out and all it does is turn off the Tv speakers
Anyone got any ideas?

You seem to be saying the bluray optical out doesn’t work? Ie nothing to do with the tv. Swap the optical out cables (you must have 2 I presume, one from tv to bluray and from what you say one from bluray out to HiFi?). Does bluray also have a coax out

No blue ray.
It's the audio optical out from the TV to my hifi amp.
Has output from normal telly or from playing DVD via HDMI to TV
No output from USB media input or from HDD recorder which is the same unit as the DVD.
Just doesn't make sense.

Oh I see what you mean, yes strange. Can you run optical direct from dvd to HiFi and then does that work when playing hdd or usb?

Only other thoughts are that stuff about set sound settings output as PCM - maybe you need to make that setting on your dvd player settings

I've always had the quirk with the HDD playback
A friend has given me a load of films on a USB and it's very annoying that I can't get the sound from the hifi.

Does your hi-fi and TV have either an ARC or an eARC socket?

[Easternlight]

No
Just don't understand why the different inputs don't all output via the optical out.

Not even the TV? try this video - if no good go to his part 3 video







And part 3...............






The HDMI ARC is by far the best route if at all doable. Hope you sort it

could be a Dolby Digital vs PCM on the inputs not being compatible with the optical out. You will need to google your TV and DVD manuals to get the audio stream setup completely.

I know nothing about this but also have a Sony TV and I am using optical out to an Onkyo AV amp. The audio does "sync" particularly easily. Sometimes I need to restart the TV and amp, mains off for 20 seconds etc etc

For me I just dont switch the amp off once its working and its all good.

The only thing I notice is PCM appears on the amp display when it's working. Not sure if switching that off on the telly would help you OP?

[Easternlight]

Cracked it.
It was the Dolby/PCM setting in the AV settings
Set it to PCM and the sound works on the optical out for the USB movies.

Thanks for the help all.

Anyway it’s good when you fix it

It was on the TV but maybe I need to do the HDD player also
