Question 10mm speaker cuts off microphone on Dell Inspiron

[BoodaGazelle]

I have a Dell Inspiron 15 3000 laptop running Linux Mint (Linux Mint 20.3 Una):

Linux mitch-Inspiron-3558 5.4.0-131-generic #147-Ubuntu SMP Fri Oct 14 17:07:22 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

Using Zoom with the built-in speakers and microphone, the sound level is very low, even with
all volume controls all the way up.

I can put in an external 3.5mm speaker which works fine, but this somehow prevents the
microphone from working.

I have also tested this with Skype and it behaves the same way.

I am guessing this is expected behavior somehow based on the hardware specs. Is that true?
If so, should a standard combo headset and mic work okay?

Thanks,
Bood

Most laptops have headphone/mic combo jacks.
one plug with left/right/mic contacts.
So yes a mic/headphone combo with one cable will work fine.
