No stereo with FM Radio after marshmallow update

[OvanTanaka]

Hello there, I have a m4 aqua e2306, everything is fine and perfect after marshmallow update, but I have an issue with the fm radio app, stereo is not working, all stations are in mono mode, and everytime I want to open this it takes like 12 seconds to open it, i tried to delete the cache/data but it didn't worked, i noticed today that the stereo mode will work only if someone send me a chat via whatsapp, notification sound starts, pauses the radio and it resumes automatically in stereo mode.

Sorry for my bad English and I hope you guys can fix it, i can see this issue was on the Xperia z series after marshmallow update a few months ago.

Thanks

I am tempted to ask you to do a software repair but let's save this as last resort.

Attempt 1) Settings, Apps, All: search for FM radio, tap it and tap Clear Data. Does it works in stereo?

Attempt 2) Settings, Apps, all: search for FM radio, tap it and then Disable, it will ask you to confirm. Do so. After it finish reading enable the app and check if it works.

If the two methods won't work, try to reboot the phone in safe mode and check if it works, if it doesn't... Software repair with XC.

If in safe mode it works I stereo, you have an app interfering with the FM radio app.

Hi @OvanTanaka,

@YoGem has some good suggestions so please do try them, but something stuck out to me, that it will work if you receive a notification via whatsapp. I am wondering if there is a conflict with a third party app that is causing the issue. Could you also please test it in safe mode and see if the issue persists?

Hi guys thanks for the reply

YoGem this is what i did before, i disabled the app and cleared the Data but its still not working in stereo.

CameronT I've tried it in safe mode but I have the same issue :(, i can't do a software repair right now again because i already did it in the new marshmallow update, my phone got stuck in the blue waves booting up after upgrading it from lollipop to M.  

The stereo mode is working not only when notification sounds is starting, It's anything that can automatically pause the FM radio and then it resumes in stereo mode, i.e using ok google, or sending a voice note in whatsapp.

Thanks.

Ok so I got this weird idea, but you know in order to use the radio you have to plug a headphone jack? Is it possible that somehow your jack is damaged and recognize it as MONO hence it try to broadcast only in Mono? Can you try with a different headphone?

[OvanTanaka]

Yeah i pluggued in 3 different headphones, but im sure its not a jack issue, Music app is working perfect with equalizer

Oh.. So the radio don't work in stereo but the Music app does... You know what, I never ever used the radio app lol - gonna try it right now to see what can be the issue..

Ok this is embarrassing, I think that the radio app is a very nice designed, app.. Some channel show the RDS and are all mostly in stereo but hey... The output is mono for sure!!!! And just the radio, I tried Spotify, YouTube RED.. All is stereo except the radio app.

CameronT, buggy App?

[OvanTanaka]

Haha yeah everything is fine except the radio app, rds is working better than it was on loll but stereo is not

So now I guess Sony had decided to stop supporting this phone, in other words this bug will be on this phone for ever...
