Hey guys I want a 3.5mm audio switch. Plug in 2/3 3.5mm audio input to 1 3.5mm output. Want a physical button/remote to change inputs. Sound will be 1 input only, no mix.
I want something like this but for 3.5mm.
There are DIY options but want something that just works.
Does this work for your use case

My bad I think you need reverse of this
If you don’t find any desirable solution you may use this cable with link you posted in your post.
Think this is what you are looking for

This is what you are looking for, but remember there might be a ground loop/ noise issues. To fix that you have to buy ground loop isolator , at least one.
Basically we are switching analog signal. So it is very likely you will get some hum or noise.
A solution is to convert all your analog inputs to digital then convert it back to analog on the output signal. This will remove all the ground loop/hum issues.
You can DIY this using a single board computer like RPI, and multiple USB sound cards for input and one high quality USB sound card for output. But this will be a lot of work and coding.
From amazon search
Something like this without the knobs.
Use case is laptop screen with 2 inputs, no sound built in. Use 3.5mm audio to speakers. Switch to toggle.
I can use the switch from my original post with 3 of these
I actually want this but with 3.5mm audio instead of the HDMI.
Somehow thought this should be cheap today?
A good quality switcher won’t be cheap, because of the analog nature of the input and output signals on 3.5mm.
Where as the HDMI one will be cheap because it is just switching the digital 1’s and 0’s. This has no noise issues to counter in the first place.
Thank you for the suggestions.
@Heisen Thats exactly what I want but 4k makes no sense.
Leaving hum aside for now. It can work with the switch in my OP and 4 rca to 3.5mm convertors. This is 300+200+200+200+200=1100 from amazon. If all this was in 3.5 mm form, it would be small size and presumably cheaper. I am amazed the chinese have not built this already.
Some DIY options but I don’t want to go this route if I don’t have to.

I have bought a driver board for a spare 11.6 inch laptop screen. Will arrive in 5 to 10 days. The board has 2 HDMI inputs, 1 usb and no audio out (I could be wrong and would solve the problem). The 2 inputs will be a mi box 4k and a broken screen laptop (both have 3.5mm audio out). Will connect usb powered speaker to the usb port of the board, if power works with screen on/off. Switchable audio input remains.
The speaker is either powered from laptop, mi box, driver board or 1.5a power adaptor.
Yes, try this setup first. It should work, I am little hesitant about the noise.
