It didn't work because that's not what 3.5mm headphone jacks do. On phones, the headphone jack (USB or otherwise) has 3 channels: Stereo output and a mic input. That's why they use TRRS. If you use a TRS cable with it, you'll get ONLY the stereo output.

Said differently, if you use a TRRS cable with the TRRS headphone jack, you'll only get a mono signal in to record. So why bother? This solution is horrible.

Use a sound interface or a dedicated device.
