I have bought a FP4 in January and since there is no Audio Jack Adapter I bought an USB-C to Audio Jack Adapter (I don’t remember the brand) in order to still use the headphones (I don’t remember the brand as well) I had before my FP4.
It worked well during 4 months. However, since 2 weeks, when plugging the USB-C to Audio Jack Adapter with the headphones the sound comes from the phone speakers and nothing from the headphones … Moreover, there is now a notification (that I didn’t have before) stating “Charging connected device via USB”
I have tried every available charging option but the result is the same in the end.
When plugging only the USB-C to Audio Jack Adapter (without the headphones), I still have the notification.
I have tried to plug the USB-C to Audio Jack Adapter in my roommate’s FP4 and he got the notification as well.
Do you know why I face such issue recently ? Is there a way to fix it ?
It’s not very specific, but I remember that in the past, I sometimes had issues with the charging port (it was micro-USB, but USB-C most likely isn’t dust-proof either ) being reduced to “charging-only” when it was a bit filled/stuffed with dust etc. (Dry) Cleaning the port is worth a try. Back then I eventually pulled out a tiny dust “carpet”.
Other than that, a hardware defect on either the adapter’s part or the USB-C port is another possible explanation, too.
