USB Aux Sound Port

[Papacraft]

I just got a Galaxy S20FE and realized I had no headphone jack. I tried plugging in a USB dongle that had an AUX sound port. The audio out works as expected. However, I don't have a microphone connected to my external speakers. Is there a way to use the built-in microphone (on the phone) while using the USB AUX sound out (to external speakers)?

You can use omni mode in the camera on pro mode but for regular use oneui 6.1 has different settings for microphones has to be pro video my bad
