Hi i am from germany! The Bluetooth volume on my xiaomi 13t pro (Mediatek, MIUI 14 Android 13) is very low on max setting. I noticed on my car speakers and headphones. I even disabled Dolby Atmos but no fix. Anyone similiar experience or found a solution? I use poweramp equalizer as a hot fix for spotify but this is not a good solution yet as it is annyoing to switch and does not work for all players
UPDATE FIX:
OK i found out how to do it!
Enable developer Options first.
Then type this into your dialer:
Phone Dialer: * # * # 3 6 4 6 6 3 3 # * # *
Then go to hardware testing – audio – volume – audio playback.
Switch to music on the second selector
Then set index 15 to 255 on each of the following selections:
BT A2DP
BT A2DP HP
BT A2DP SPK
Volume should be boosted right away! Cheers! 😗👋
look at the developer options
whether have Bluetooth settings
So i have tried every setting there is but nothing worked. I also tried disbaling absolute volume under the Bluetooth device specific setting for my headphones but still no change. Changing Region to Swiss also did not help. Any idea?
Hast du deine Region gewechselt? Probiere mal USA aus
Ja! Und leider hat auch ein Neustart keine Änderung gebracht 🙁
Ich habe oft gehört, dass es am chip (mediatek) liegt 🙁 eins der Gründe wieso ein mediatek mir nichts ins haus kommt
Das wäre natürlich wirklich schade wenn das so wäre. Ich bin eigentlich sehr zufrieden mit dem Prozessor er ist sehr schnell. Der schnellste den ich bisher hatte.
Habe die Lösung gefunden es war eine geheime Einstellung 🙂 Siehe Post
Found the solution check the post!
good
It is for Mediatek only and my guess is it is only for specific models of it. But i am no expert
You can also disable absolute volume in bluetooth settings
Tried that but it had no effect on this device at least
Thank you very much for this information. Was about to bin this phone😁🙏
You are welcome! 🙂 It’s a great phone i like it
Try and working on Xiaomi 12T via android 14 worst updated.
Muchas gracias por la información, yo dispongo de este teléfono y tenía este problema. Me has ayudado a resolverlo. Ahora todo Genial. 👌😁
🙂
I love you, just know that, you saved my day with this tip!
Thank you
<3
You are Welcome 🙂
Value 255 is fine 🙂 it’s the same for me
Alter hat mich das kirre gemacht 😅 ich dachte ich hab irgendwelche settings falsch eingestellt. Danke für den Tipp
Gerne 🙂
Bro thank you so much! I accidentally rejected the permissions for Engineer Mode and I had to found them and change them manually (Ik I’m idiot xd) but then I finally used your manual and It works! U have my thanks 🙂
And Greetings from Czechia 💪🏼
you are a life saver friend 😀 thanks!
Thanks man ! Really appreciate it. But one question, didn’t the speaker will jump great gap only for max volume if you only adjust index 15? Also, as soon i try your method. I saw the speaker option under all 3 Bluetooth option. Should i follow or copy all value from index 0 until index 15 from “Speaker” option and use it on “BT A2dp SPK” option which means bluetooth speaker option? I don’t know if you understand what I’m saying and im sorry but you really really give me the answer I’ve searching for so long man thankss
You need to change all of the three bt values if you use Bluetooth across different sort of devices. Yes you can also change the values to your liking to make it a smoother transition. But imo it wasnt necessary as the last step wasnt that big of a jump.
Ok so I have this problem on the 13t pro and I did what you said here but it didn’t really change the volume of the Bluetooth, wireless headphones are still super low, car too 😓
Make shure you switch from “System” to “Music” selector before changing the parameters
Te amo meu amigo, eu estava preste a trocar de celular, pois pra mim é impossível ouvir música sem ser no máximo.
Hi, I did change index 15 to 255. Works for me. What i noticed next is the huge gap volume between index 5 and 6 and very low volume from index 1 to 4. already changed the values for smoother transition but nothing happen.
I noticed when connecting to my wireless buds, when playing game, audio is delayed. Does that happen to you?
Very useful, thank you so much, also look for Dolby effects on settings and turn on immersive sound, it worked for me.
I noticed too.
hi please you can a make video show us??
Thanks man, helped a lot! It’s so loud that it even hurts my ears now 🤣🤣🤣
Take care of your ears! Tinnitus is horrible! 🙁
Thank you very much!
Can we change the volume index from 255 to 260 incase if we feel that’s still a bit low and could be more better?
255 is max
i also have the same issue with wired buds , any fix ?
Try to change a different setting. This was for bluetooth but there is likely one for the wired output aswell
i got 11T and 13T pro , sound really good with same settings on 11t , but 13t so low … its irritating when gaming
Hi, i unfortunatelly set these parameters on System not Music can i reset the settings or what are the original parameters for this
Thank you!
maaan, thank you so much. I’m sure this bug is related to “you wearing headphones for too long” feature. It exists since mi 8.
You are welcome. I think it is not a bug but there to keep up with regulations. Am no expert though…
Goddamn, thank you. Now my Redmi Buds 3 are loud again on my Redmi Note 12S.
any ideas why i cant see the hardware testing option? i use xiaomi 13t pro aswell
Did you enter the code into the dialer?
Thanks man you saved my day
FYI: this does not persist on reboot/update!
For me it does! Update and reboot
Thank you so much brother
Thanskf or this. I can finally play pubg again. Have you got a fix for the battery drain, too?
Not very specific but you may reduce display refresh rate to 60 and disable some features like always on display and varoius other small things that use power. Personally i don’t have issue with drain as the phone charges very fast.
Thanks for the tips. I wish the phone would allow users to swith to 90hz and a 1080 FHD resolution. I only get around 3 to 4 hours of onscreen time. I have only sued the phone for 3 days so maybe the software will optimise further as it understands my usage pattern.
You should get much more!
Either I’m stupid or I can’t find hardware testing
You have to swipe to right twice
Where exactly? In developer settings or what?
You need to type the code into your phone dialer and a menu will appear
Oh, ye I typed that but nothing happened
Correct phone?
I think I have Xiaomi 13 when I type the code the code just disappears so idk
This is only for Xiaomi 13t pro with Mediatek sorry
Sir have you experienced bluetooth audio glitch from your 13T Pro?
Like when playing music through bluetooth and it’s intermittent?
Man, thanks a looooot
Need this but for note 13 plus pro please
I think this is a problem of a chipset. You see, I also have the same issue on my POCO M5, it has a Mediatek chip. I tried connecting Bluetooth to my second phone which has a Qualcomm chip, and everything works fine. This problem probably cannot be fixed.
Does any1 know why the settings don’t save when I press “set”? I switch to music and all but when I press set nothing happens and when I check everything is back to default. Note that I own a 13T not 13T Pro
I assume because this is a different model and processor it won’t work. I can confirm this to be working for 13t pro only
using redmi note 13 pro 4g , meidatek processor .
applied all setting mentioned here or any other mentioned on youtube videos no luck.
i have galaxy buds2 pro blutooh just to update, if anyone can help.
same headphone i sue with my s22 ultra it is boom.
on my asus laptop too high .
only redmi note 13 pro low even half than the other devices
Thanks man Worked on my Redmi Note 13. Noticed right away the volume seems toned down using my OnePlus buds 3. I was using S21 plus before.
Can confirm it worked on my Poco X6 Pro
Thx. Volume was way to low. I could still hear my wife talking while playing Metallica. Problem solved. Lives saved.
It is just called “audio” under “hardware testing”. If nothing is there you might have a different model…. Only for Xiaomi 13t pro
Does anybody know how to do this for Redmi Note 10 Pro? Is it possible? Thank you🙏
Lebensretter
Hi. Is there any solution for poco F5 pro with the same issue. FIX above doesn’t solve the problem for poco (yes, i can read for which phone is provided).
Regards
K
Thank you so much!!!
I have a redmi note 13 pro and I paired it with some skull candy dime 1 , after I saw that it was not giving me good audio (I tested the earphones with a A51 and the audio was perfect) I searched for this problem and I saw your post , I just did that tutorial with the engineer mode and it didn’t work . I also have Xiaomi HyperOS if it helps w/anything
Same to me.
What if I did it and did not change anything ! Is there any other feature to deactivate?
Same here , did not work
I have a Xiaomi 12 5g. Have the same issues playing music so low sound
Don’t have hardware testing option or audio in Developer options . Can anyone help
IT WORKED TYSM
Thanks man, it worked on my redmi 12 with hyperOS. Now my music is actually audible. I still have to use max volume, but now atleast I can hear it through car radio or public transport noises
is there video to this, nothing shows up when I did this with my 13t pro
How i do this with xiaomi 11t i can get the menu but it dosnt get options like that
I think i got it now trying to restart and try 🙂
I got it working man you an og i allmost was ready to broke my phone and buy new phone hahaha
*Need Help* (I have a Xiaomi redmi 13 5G) for the last step, I just have index 1 to 15 and it’s only numbers, I can’t put any letters and I don’t know what I have to do, HELP PLEASE
You are the Greatest. THX. I was going to buy new smartfone because of that 🙂
<3
Thank you 🙏

Thats my steps in the Volume settings and the step 5-6 is in Volume so much louder in my Bluetooth speaker… Ist there anything i can do to get smaller Volume increase?
May have worked on the Xiaomi 11T.
Was on Taiwan region before if that mattered. The value of the first one was 200.
Unsure whatever it helped on the Xiaomi 11T.
Not a massive difference at-least, 200 originally on A2DP.
Ok so I found all the settings but the index 15 is already at 255 on all of the selections? It’s not changing anything?
No you’re supposed to change the category to the letters mentionned, it’s at the top of the screen, then change each index 15 value to 255
What did u guys do then?
Worked for me on Xiaomi 13t Pro android 14
after inserting \* # \* # 3 6 4 6 6 3 3 # \* # \* it tries to open Engineer mode but instanlty fails > Permission denied. I cant find ho wto grant those permissions..cnyone can help?
Have you enabled developer options?
Yes, 7 taps on phone info, says dev mode enabled. My model redmi13pro (non-T)
You may have the wrong model. This is only for Xiaomi 13t not Redmi
it worked for me for the Xiaomi Redmi note 13 (5g)
for me it does too, Redmi Note 13.
Actually, after the reboot I also get a quick message saying “Volume is boosted” or someting similar.
The workaround works for my Xiaomi Redmi Note 13 (5g) too.
Now after any reboot, before I even login, I get a message “volume boost is on” the bottom of screen that disappears itself after a few seconds….
Odd, on my 13T the settings are lost even before I reboot the device.
Bonjour je suis arrivé au mode test matériel mais après pourrais tu être plus précis pour les manipulations je suis perdu. Merci
Definitely isn’t enough if it helped at all on Xiaomi 11T.
What’s the easiest way to get global ROM?
Had missed the music step and only adjusted for system.
Now it seem to work.
Is there Something similar for the 12 T Pro?
FINALLY a fix for low bluetooth Volume, THANK YOU SO MUCH! redmi note 13 pro plus.
works! got the 13 pro plus
I have to update myself as I figured it out – this **might** get undone on a **region change**. So if you change regions to get updates sooner (Ireland FTW), you might lose these settings and will have to redo them.
Anyone with a 11T Pro that solved this problem? Thanks!
I can’t use this code man, any other option?
Vielen Dank fürs Tip, made my day man
Hello I have one same phone but I can’t see hardware testing option..
how to increase yt videos volume? it worked for geberal audio/music but if i use yt music/music videos they’re much lower over bluetooth speakers then if i play music over my music player app
is it possible for someone to share their default or working settings? when i go from audio level 4 to 5 their is such and high increase in volume, but i dont see anything wrong in the developer settings as shown above. and its only when i connect to bluetooth speakers or headset.
i have the same thing, did you find out why perhaps?
hola en mi Redmi note 12s no se guardan los cambios que puedo hacer
Jai le même soucis, impossible de le régler, quelqu’un sait faire??
Wata actual sht it actually works!!! Thanks mate
Hi could someone share the default values for the 15 index? With some BT Devices the sound is distorted so i prefer to reset to its initial state.
Thanks
not working on Xiaomi Redmi Note 13 5G.
I was using a s21 FE before my my earbuds are too quiet on my Mi 13 lite
perfekt👍 läuft auch no h genau so mit dem hyper os 2.
Milles merci pour l’info🙏
Thank you so much.
Hello this is very good but dont put it to 255 i putted it and had to decrease them because i could voltrol volume (had zero volume incmy phone but still keeps blasting 100%
Ça fait 3 mois que je suis embêtée avec ça j’ai acheté 2 paires d’écouteur pour 300 euros le tout j’avais toujours un son faible , jai appeller xiomi qui m’ont dis que je devais renvoyer le téléphone exprès . J’allais le revendre ce matin même car j’en avait marre et cherché une dernière fois un miracle pour éviter ça et grâce à ton poste ça m’évite de revendre des affaires pour racheter un téléphone je te remercie énormément 😀👃👍
I have the problem with my x14 ultra but not working ?
Can someone help me pls i changed these settings and now i cant controll my bluetooth volume anymore (very loud even when media sound muted) ive tried to lower The 15 to 52 in the 3 bt thing but it didn’t resolve :///
THANK YOUUU!
Cara nem te conheço mas eu te amo, estava arrependido já de ter comprado este poco x6, as configurações mudam um pouco mas o processo é basicamente o mesmo.
Vida longa mano!
Can this damage the headphones/earbuds due to high distortion?
Komisch, bei mir geht es nicht, aber jetzt gibt es nurmehr zwei Stufen, nämlich “mute” – also stumm – oder “voll”, aber das höchste Audiolevel ist immer noch wie vorher. HAt jemand vllt eine Idee, woran das liegen könnte? (Xiaomi Redmi Note 13 5G)?
1000 Dank fürs Denken!
Thank you, great job. What was the defaults? 😁 Or, is it possible to rollback completely set to the audio defaults? Regards..
irgendwie komm ich nicht weiter…geh mal davon aus das man \* # \* # 3 6 4 6 6 3 3 # \* # \* dort wo man auch telefoniert eingeben soll…passiert aber nichts…und in der einstellung für entwickler optionen selbst finde ich auch nicht diese einstellungen…pls help
I also had this issue but managed to fix it.
Enter ur values under “music” and “BT A2DP” First should be 0, second index 88, then keep adding 12 on the number prior to itself until u reach 255. That will fix the jumping between step 5-6 and generally stay even between all steps 🙂
0
88
100
112
124
…
Etc.
Hope this helps!
Merci !
THX dude 🙂
Thank you so much. Just worked! Just did it now! Thank you dear redditor. Bless you!
