Honor's FM Radio

Hi, testing "FM Radio" app embedded on my Honor 200 lite (Android
 14) it requires to plug in audio jack or adapter to go.  This
 Honor doesn't come with a jack port. So when I plug in a "usb-c
 to jack" adapter I get a "wrong port" warning from FMRadio app (
 ...although the adapter works fine playing any other
 multimedia).

According to Termux there is a FM chip and it's running, isn't it?
getprop | grep -i fm
[init.svc.fm_hidl_service]: [running]          
[persist.vendor.connsys.fm_chipid]: [mt6631_6635]

It doesn't seem an hardware issue but I can't uninstall this
 (bugged?) FMradio app rootless.

How to fix it?
