Apple EarPods use a special/different type of connector layout called CTIA.
Your Macbook works perfectly with CTIA headphones because they are both Apple products and implement CTIA. Your ubuntu setup most likely uses OMTP.
Here is an image depicting the mismatch:
This incompatibility will prevent you from using your Apple EarPods
You headphone has a TRRS (tip-ring-ring-sleeve) connector. Which can be seen below.
Black rings separates the signal contacts. Here we have 3 black rings and 4 signal lines (contacts). These contacts are used for;
So, we must have 4 different contacts in the host device's connector (for example you laptops audio jack) to be able to use all of those signals.
You are telling that "I can not control volume via using the headphone's buttons". In this case we have to ask these questions;
If you can say "yes" to all of the questions mentioned above but still Pc is not understanding the buttons, then;
You don't say what device you are using but most modern laptops with one socket of that type will , when correctly setup, prompt you to select what type of device you have plugged in and configure the port appropriately.
That this is not happening suggests that you have not got the right profile loaded for your computer's (laptop ?) particular chip layout.
