Hi, I'm having a issue with my redmi note 9 pro. Whenever i try to make a call, it always goes to speakerphone. I cannot get it to go to the earpiece. WHen i try turning off speakerphone, the audio is still routed through the bottom speaker, and the person on the end of the call notices i sound broken up. WHen i swotch on the speakerphone the sound is clear, and then the person can hear me just fine. I've tried with whatsapp, google voice, and the regular phone app, and all have the same issue. I'm running Evolution X currently as my rom, but i've tried lineage os, and it has the same bug. On stock MIUI I don't remember having this issue, so maybe it's something weird with the custom roms. I'm also rooted with magisk. Anyone got any ideas, or has anyone ever experienced this issue when running custom roms on this phone? Any ideas, or suggestions are welcome. Thanks

Hi, I have this problem too. Of course inside the pubg mobile game. To temporarily solve this problem, first turn off the phone and connect the headphones when the operating system logo is displayed. A hissing sound is heard when plugging in the headphones.
Of course, to avoid this problem, you should use Bluetooth headphones.

Hi, I just tried your suggestion. it doesn't appear to work. My issue is with the earpiece, not headphones. Headphones for me have always worked flawlessly when running custom roms or stock. My issue is when making calls using the earpiece. Making calls using headphones seems to work fine. However when trying to use the earpiece, i cannot get it to work. What i mean by earpiece, is the top speaker of the phone, the one you have to hold close to your ear when making a call. FOr whatever reason calls always remain on the bottom speaker, and never seem to go to the top speaker aka earpiece. This happens in all calls, and in apps like whatsapp. Has anyone else ever experienced this issue? Again, headphones seem to work fine, and yes I'm rooted, and running a custom rom. When i was running stock, I don't ever remember this happening, but now that i'm running a custom rom, i can't get the earpiece to work. I really don't want to go back to the stock miui rom, but idk maybe i will if a solution can't be found

I am having the same problem - BUT on stock MIUI 12.5 - it started happening after I upgraded. If I could go back I would, but am happy to flasha new ROM if that will fix it.

I was thinking of flashing Lineage 18.1 but if that is having the save issue I ont bother. It must be a note 9 pro issue seeing as I only have the stock version..
I wonder if anyone at all has fixed this issue. I even contact xiaomi technical support but they were useless!

I'm having the exact same issue. When I initiate call it's on loudspeaker even though I didn't select that option. The other side can't hear me well. When I select "speaker" then it's still on loudspeaker, as it should be, and the other person can hear me fine.

I had the problem on crDroid (Android 12) and am currently experiencing the same problem on Pixel Experience (Android 12).

Please help someone us :(

I found the solution when I changed sim 1 to sim 2 the problem was solved.
Not quite sure I follow. Are you saying to remove sim 1? Or are you saying to change the default calling sim to sim 2 or something? I should note that I'm using both sims and a SD card. Are you saying I should just use sim slot 2?

I found the solution when I changed sim 1 to sim 2 the problem was solved.
Short version:
OK, so I just tried your advice, and it WORKED.


Long Version:
Ok, so I first removed both sims with the phone off. Then i put one of my 2 sims ONLY in slot 2 like you said. I inserted it into the phone, booted it up, and made a test call. To my surprise, the phone wasn't on speaker. I couldn't beileve it. I tried again, and it worked. I switched to speaker, now it's on speaker. I turned off the speaker and it was back to the earpeice! I tried whatsapp, and same result, the earpiece was working. I then decided to shut the phone down, and put the both sim 1 and 2 back in the phone. Guess what? after booting the phone up again, and making a test call, it still works! I don't understand the rhyme or reason behind it, but I'm not complaining. I'm so happy it FINALLY works.

to recap, Basically here are the steps:
1. Turn Off phone
2. Remove both sim cards.
3. Put a sim only in slot 2
4. Turn on phone and make a test call, it should no longer be on speaker!
5. go ahead and shut down the phone, and put a sim in both slots, if you are using 2 sims.
6. Turn the phone back on, and make a test call. It should still be working on the earpiece!

yes - this worked for me also - I have been looking for so long. A simple and un-remarkab le solution to a serious problem. Xiaomi should have been able to solve this.

All the same - thank you!

Great phone that was hindered for quite a few months by this serious problem

Again - thank you !
