Question regarding TV set audio output.

[avz]

Maybe my question is not exactly for what is the forum about but I'll take my chance. the question is about a domestic tv set. of course it's a Chinese label product. I need to have an audio output. of course it has a 3.5mm earphone socket but as you know, if I insert the 3.5mm plug into it, it mutes the internal set's loudspeaker and I want that the loudspeaker will keep playing while the plug is inserted. is there a possibility to withdraw the audio from the HDMI port on the tv set? is there any other idea/possibility to do it? I would like to mention that it has an optical port as well.

The mute is done by mechanical switches in the jack. Of course, you might not want to do this but if you remove the rear cover, you can join the terminals to prevent this.

You can buy devices to extract audio from an optical output, and even from HDMI - but only if it's an HDMI-ARC port, most modern TV's should have one that's specifically labelled ARC, if nit then there's no audio output (HDMI on a TV is obviously input only).

Easiest way is to simply stop the earphone socket muting the sound - but (depending on how it's done) this may not be possible. I've converted many sets over the years, but many modern sets do it in a completely different way (the switch on the socket sends a signal to the microcontroller, which then disables the speaker, and enables the headphone socket), and so it can't be done.

If you don't want to try modding it, then buy an optical to audio converter, freely available on Amazon etc.

As I've just mentioned (at the same time as you were typing) that's how it used to be done, in later sets it was often not done that way.

The tv has a HDMI-ARC port but if this option is chosen - will it enable the internal speaker to keep on playing?

Thanks, but I don't wish to make such an change unless there are no other options.

Another way to have a headphone feed and an open speaker at the same time is to use a 3.5mm splitter to feed the headphone and an external speaker.

It would almost certainly need to be a powered speaker though, as headphone outputs are usually power limited.
