I recently bought a USB-C to headphone adapter so I could use my phone with the Aux input in the car. It’s going great except the phone mic doesn’t work when it’s plugged in.
I semi-frequently use voice messages while driving to avoid looking at my phone and this isn’t an option now without unplugging the USB and replugging it which is distracting so defeats the purpose.
Is there a way to force the phone mic through settings or similar?
Lesser AudioSwitch sounds like it would do the trick but doesn’t seem compatible with my device
It sounds like the adapter is trying to provide the mic in on your phone.
Test by seeing if the mic is suppressed by having only the adapter plugged in but no aux. If the mic works appropriately with no aux, how many black lines are on the aux you’re plugging in? If there’s three, then that aux cable is a TRRS 'requesting" mic control. If you can get one with 2 (TRS), that might resolve it.
If the mic doesn’t work with just the adapter, then it’s the adapter’s fault.

Nice one. This sounds like a good option. I’ll check in a bit.
Update:
There were only 2. I unplugged the aux cable but left the USB to aux in and the mic is still tied to it unfortunately.
Thanks for your help. Looks like I’m a little goosed.
