I am trying to pass audio from a laptop to a desktop via a headphone jack from the laptop to a line in on the desktop but it provides constant static. I have tried two different aux cords (new). I currently think I might need an USB to Audio Jack Sound Card Adapter but don’t want to buy this too and have to return both if it does not work. Do I need it to be a line out and not a “Headphone Jack” or a sound card?
Thanks
Just in case: what about my question (1)? You are plugged in to a line in and not a mic in, right?
I’m pretty sure ground loop can’t occur on a laptop when it isn’t plugged in to the wall for power. From a quick search, this seems to confirm that:
I’m seeing that, beyond ground loop, noise like this is probably some other form of EMI (electromagnetic interference), often from bad capacitors. I don’t really have experience there.
I’m sure enough that the ground loop isolator won’t work that it will probably work. So try it!
If that doesn’t work, I think a USB audio interface is the next solution. Since you were still getting hum (albeit less) when plugged in to the the monitor, a new interface from the laptop should work.
Yes it is plugged into the line in
And I will most likely try that ground isolator thing just in case who knows but also try and see if I like the network solution if there is little lag that will work but if not I will look into an interface.
Thanks for helping me troubleshoot and let me know if you think of anything else.
