FM Radio

does not recognize headphones, tuner does not recognize any station
https://gitlab.com/LineageOS/issues/android/-/issues/2272

after plugging in headphones and opening the FM radio app included with LOS,
it should start transmitting (the default status when launching the app seems to be “on” )

The app does not recognize headphones (I’ve tested several, only one was recognized).
Using Lesser AudioSwitch to force the phone to use the headphones by default, the FM Radio App tuner fails to recognize any FM radio stations,
and only transmit sizzles ( the headphones works when listening music, video or internet radio)

When I launched the “search” stations, the app looks at FM radios, but find none, and shows an erreor message : “no compatible station found”
