Please make smaller screenhosts or simply use code tags for such stuff :#Your code here Or here! :) -
@nero355 I would like to apologize for the photo that is a little too large. If my smartphone hadn't been messing around like that, things would have turned out differently. Let's see if I can get these photos even smaller with the PC.
Hello as you see in the picture no output. But the funny thing about the thing is that their commands only sound the microphone instead of the radio on Merlin. But it's the right direction. An MTK chip is built in, so much we already know. And also the kernel crash is no more. At least that's how it is with me on the Merlin. Thanks for your work.
What does FM radio mean, is it a niche product? Unfortunately for many smartphone owners there is no other alternative to listening to the radio when you are on the go and have no internet. Unfortunately there is no successor to the LG Stylus 2 that Dab + and FM had. I think it's good what the blogger @mardy has done. Maybe you can somehow get the radio to work at the Merlin.

Can you please paste the output from this command?
ls -l /dev/radio* /dev/fm*If you get something, there's hope it will eventually be supported

@mardy Volla OTA-20

@mardy Xiaomi Redmi Note 9 Merlin OTA 20
I have an FM app myself to test it, there comes something with Com from time to time in the log. I thank you for your help anyway. In the Xiaomi Group, I made people aware of their blog. Let's see if there might still be radio at some point. Even if you say there should be something in the terminal. Wait until Focal has been ported, better kernel and so I guess.

It's not a big deal but it's just soo annoying to see any of my monitors suddenly downgraded to one of those old 14 inch CRT monitors with 640x480 resolution!
We have a Terminal app which you can use to copy->paste stuff.
You can do the same via ADB and a PC or Laptop while your phone is connected via your USB cable.Let's not waste screenspace together!

@nero355 Sorry, I'm not a professional with UT yet. Ok, that's good about the Adb and the PC. I still need help with that too. But I understand your objections

@mardy hi, so
/dev/fmdoes exist on the redmi note 9 (merlin) and the redmi 9(lancelot) just like on the vollaphone, however the volla fm radio app crashes the phone whenever the radio is started.according notkit the crash occurs somewhere in here: https://github.com/MiCode/MTK_kernel_modules/blob/lancelot-q-oss/connectivity/fmradio/core/fm_main.c#L242
no idea why at the moment@dpitti hear has been tweaking the volla fm radio app to find a way to have it not crash over at https://github.com/1978Enrico/fmradio-volla
it should be noted that the both merlin and lancelot have a shotwave antenna, i am somewhat hoping to build a check somewhere that the app doesn't prompt for the headset. but perhaps this could be a part of the radio service checks, whether an antenna is available, headset or shortwave.
on merlin and lancelot the presence of a shortwave antenna can be queried withgetprop ro.vendor.mtk_fm_short_antenna_support -
@fuseteam Good morning, or could it be that we see the WiFi antenna instead of the FM antenna? Just as a question because in most cases the headset is used as an FM antenna. If the internal antenna will only bring something close to the transmission mast either way. In the rural region you always have to use a headset or an antenna with a 3.5 MM jack connection.

@dpitti hi, no it is really the fm radio antenna. i have no idea what they did physically but the redmi 9 and redmi note 9 do not need the headset to act like an antenna at all. in cases where does not have that antenna that command returns either nothing or
0i'd imagine -
@fuseteam Thanks for the clarification

@dpitti sorry for the late reply, I missed your message.
If you install the official MIUI, you'll find a sub-group of apps (unfortunately I don't remember the group name, but IIRC there are only 3 or 4 groups, so it won't take long to find it) which contains the FM radio app. It's preinstalled, you shouldn't need to download anything.

@mardy Don't stress I'm back on Lineage OS 19 now. I found your thread about the FM test a long time ago. I will buy a used Xiaomi Redmi Note 7 if I find something else. My Xiaomi Redmi Note 9 lost the imie when flashing, so I'll leave it like that for now. But thank you for your work for FM.

FYI : You can fix that IIRC so check out XDA Developers Forum and I am sure you will find a solution!

@nero355 My device is now running again but with Lineage OS. Can also make calls again where I'm happy. I'll probably get a Xiaomi for Ubuntu Touch again. First of all, I'll take it easy when it comes to FM radio and such.

Hello @mardy
Can you please clarify the status of Volla regarding FM ? Will it eventually be able to support the FM ?
Thanks -
@mardy with the last Devel Update works the FM Tuner out off the Box ( Miatool Xiaomi Redmi Note 9 Pro ). The Porter have fix the FM Tuner

@mardy The Ukw radio for Ubuntu Touch seems to be set too high in sensitivity. There should be an option somewhere where you can change this. So some stations that are below the level do not run at all. I live in the countryside so it would be good to keep the squelch of the app as low as possible. I would recommend the value 10 if the app can do that.
