The Headphone Jack is line level only output it needs amplification.

Though you could be trying to get sound via a USB Sound Card or HDMi ?

Im not shure what you meant by that, but if you simply want to make the jack port output sound, just do the following command:

Code: Select all

sudo amixer cset numid=3 1

I hope I helped you somehow.

is the "speaker" system amplified
amplified means there is a power in port (either barrel jack or microUSB/miniUSB etc), and usually have a volume control knob (optional)

or plain boxed speaker, with just the headphone jack as connector.

you may be able to test the sound output from the audio jack (TRRS jack) using plain headphones (I tested it before and it works)
if you can hear audio from the headphones then the audio jack works
otherwise you need to set the RPi to output audio to the audio jack,
the settings can be done in rpi-config, set audio to output to analog.
you may have to reboot.

if you are using Raspbian Stretch Desktop, you can change the audio output by right clicking on the speaker icon, and selecting analog. You still need to do a quick reboot for it to take effect.

now after confirming that audio does output to audio jack, connecting a plain boxed speaker to it will still output audio, but you will have to place your ear very very very close to the speaker.

that being mentioned, it is better to have an amplified speaker instead

if you still want to use your boxed speaker, then you need to provide an amplifier. An ultra low cost 5V, 3W amplifier module is available in amazon or your favorite shopping site/ local electronics shop.

do tell us what you intend to do.....

Perhaps I can make this a little bit simpler...

To use just speakers with a Pi, they need to be self powered. The typical "computer speaker" sets work this way.
