Speakers registers as headphones

So, I solved the problem. Apparently, without access to the "microphone" the eqMac2.app will not work AT ALL. So trying to set an EQ filter in any source leads to a complete absence of sound.

This was step one, step to was the output source missing. So apparently, when having headphones plugged in to the outlet they become "Built-in output". So, without "headphones/speakers" plugged in, the "Built-in output" are the laptop speakers. After plugging in your headphones/speakers, this option in the output selection becomes your external "listening device".

So I have a MBP and it only has one 3,5 mm female outlet. I realise that this is likely supposed to be for headphones and not for speakers and I should use something else. However, the actual problem here is not really that my speakers are not recognised as speakers but rather that "headphones" are not getting updated and included as available outputs in apps.

I did plug my speakers in and the EQ app worked, as intended. I left my office for a while, came back and after unlocking the screen, the eqMac2 app no longer recognised the speakers. So the app should be able to apply EQ settings to headphones (as Boom3D does the exact same thing and as this is an advertised funciton) though the "headphones" (my speakers) does not show up as an alternative in the output menu, same thing happens in Soundflower.

So I was just looking for a quick workaround if one could just specify "headphones" as "speakers" quickly in any setting to solve this. I'll just keep looking for a solution, thank you for your input.
