Connect pc speakers to tv without 3.5 jack

[nomoresonys]

Currently trying to connect pc speakers to 2015 vizio tv, tv has no 3.5 headphone jack. Does have rca audio out, tried connecting thru a Y rca to 3.5 cable but getting odd results(probably just need a dac for decent audio, not sure?) not too educated on audio. With that hookup I'm getting 2 problems, can't get the speakers to increase in volume so it's very low even when turned up and when using both tv and pc speakers the pc speakers only put out the music part of the broadcast and not the vocals/talk of the program. Have you run into this before or know what it might be, Thanks.

Sorry bout that, should have mentioned that I'm trying with this adapter, it has the red, white and yellow rca to 3.5. I was probably wrong thinking I could just use the red and white to make it work?: https://www.amazon.com/Auxiliary-Ste...09VK9VP31?th=1

That depends how your adapter is wired
It can be either
Tip - audio L (white)
Ring1 - audio R (red)
Ring2 - video (yellow)
Sleeve - GND

Or
Tip - audio L (white)
Ring1 - audio R (red)
Ring2 - GND
Sleeve - video (yellow)

Can't trust this type of adapter/cable without measuring with multimeter, same issue with old camcorders and some other devices which use a similar cable (4 pole 3.5mm to 3 RCA), depends on manufacturer which pinout they used...

You can try thIS, short the tip and sleeve on the yellow RCA plug with a piece of wire , that way you're getting the GND connected

This type of adapter should work

Tried with tv speakers set to on and off also with speakers set to both fixed and variable, same results.

rca/scart outputs are not amplified - you need to add a small amplifier.

[CapLeaker]

Yep. The audio level is different and is not adjustable.

[nomoresonys]

So a dac won't work for this? Which kind of small amp, can you link an example, Thanks for replies.

[stj]

how many watts are the speakers?

[m1ch43lzm]

There's also S/PDIF Digital Optical audio to analog RCA converters, plenty available on Amazon/ebay, if your TV has optical audio output
Assuming your PC speakers are powered either by USB or mains power (have an internal amplifier, with a volume control) the RCA to 3.5mm adapter should have worked

You may hear a similar effect to what you describe if for some reason the GND is not making proper contact (only the L and R signals), the wire is internally broken, or when the 3.5mm plug is not fully inserted into the jack

Check the wiring on your adapter with multimeter, or make your own, like this:

I'm trying with these Cambridge SoundWorks Creative GCS300 Computer Speakers, it says 300 w in one ad but 5 w in another so not sure. Plugs into outlet and has volume control and power on/off button.

https://www.ebay.com/itm/17737459809...DKT7M52K50KGQG Ok, have a dac adapter ordered, hope it works or at least gives a little better sound. Had same issue with 2 sets of speakers guess they are ok. Only have the one Y adapter, will try checking the Y and connections. Thanks for help and for the illustration of adapter.

You can try thIS, short the tip and sleeve on the yellow RCA plug with a piece of wire , that way you're getting the GND connected

I checked continuity, here's what I have, not sure the terms so I'll call the tip 1 and the next 2 and 3 and 4: so tip-inside white: 2-inside yellow: 3-red, white, yellow: 4-inside red. I had red and white thinking that yellow was for video but might be wrong. You think it would blow something if I tried different combos like yellow and red or yellow and white? Thanks.

Going to try the short now.

To add to the confusion, more pinouts, all incompatible with each other
https://pinoutguide.com/Audio-Video-...k_pinout.shtml

Assuming tip is 1, then your cable is wired as Sony/Panasonic pinout from that list, so tip is white, 2 is yellow, 3 is GND, 4 is red
Use the yellow RCA plug as your right audio channel (red), then short the red RCA plug from that adapter

More examples of the confusing non standard pinouts

Best to make your own adapter with a 3 pole 3.5mm jack, or buy the appropriate one

THANK YOU SIR, you are right on, shorting tip and sleeve of yellow/inside to outside did the trick.

[nomoresonys]

Thanks I'll get the correct Y cable, Your grounding solution worked like a charm, it sounds fine now but looks a little funky with my wire and alligator clip rig up, lol.
