This tutorials will teach you how to increase sound volume for earphones, loudspeaker (rear speaker) and normal speaker (front speaker). You can even calibrate sound volume of your Redmi Note to adapt with your hearing. The best part is, you don't need any Ginseng Root for this! It might take some trial and error to calibrate your sound, so you must have the patience to do it.
So here's the tutorials:
Step 1 - Put Your Engineer Cap On
In your phone app, and dial *#*#3646633#*#* to enter MTK Engineer Mode. Go to Hardware Testing and choose Audio.
In Audio, there are a few options. But for this tutorial, we will only use 3 modes.
- Normal Mode - Front Speaker for listening to calls
- Headset Mode - Headphones, Earphones
- Loudspeaker Mode - Rear Speaker for Media and "Speaker Mode" for calls
You can choose the mode accordingly to calibrate your preferance sound volume. There are a lot of type in each mode. To enhance the overall sound volume, we usually tune Sph, Sph2 and Sip type. You can notice thatSph and Sph2 have the same value for each level.
You can see that the Max Volume for Sph cannot be editted. If you insist to increase the max volume, chooseSip type and increase it.
- For Normal mode, sound type consists of Sip, Mic, Sph, Sph2, Sid, and Media.
- For Headset mode, sound type consists of Sip, Mic, FMR, Sph, Sph2, Sid, Media and Matv.
- For Loudspeaker mode, sound type consists of Ring, Sip, Mic, FMR, Sph, Sph2, Sid, Media and Matv.
Extra info about the types:
- Mic = microphone receiving sound volume
- Sid = background noise
- media = media sound volume
Step 3 - Calibrating and Testing
Notes before calibrate:
- Tune one type in one mode per time and test it before going for another. Do not calibrate all at once as you will get confused easily.
- It is advisable to set Value not more than 250 and Max Vol. not more than 150. Setting them to maximum might spoil your phone speaker or your ears.
- Sph and Sph2 need to have the same values for each level.
- Let all values be ascending order in its increasing level. I hope this is a common sense for everyone.
Baby Steps to calibrate on each level:
- +5 for each level and test the sound volume on respective sound system.
- If the sound is not loud enough, +1 or +2 for each level again and test it.
- If the sound is too loud, -2 for each level and test it.
- Increase and decrease the value until you find the volume is clear from noise and satisfactory.
1) Adjust sound volume when receiving calls
If you think your phone has low sound receiving other calls, you can tune in this mode. My advice is you only need to tune level 6. I bet most of us usually put max volume in call. Oher levels can be ignored as we are less likely using them. For this, we can tune sph and sph2 type by following the baby steps above. Increase the value and Max Vol. in Sip if you are still not satisfied with the maximum sound.
In occasion case which you want to lower your call volume, you can adjust the same value.
The following table shows the default values of each level for sph and sph2 for Normal Mode. Max Vol. is 128for all levels.
The following table shows the default values of each level for sip for Normal Mode. Max Vol. is 128 for all levels.
There is hardly people complain about speaking sound when calling. But in case there are people complaining that your voice is hardly heard or too loud during calls, you can adjust the value in Mic type in Normal Mode. Note that there are 14 levels of it. My advice is, tune the value to 192 for level 6 to 14 and test it first. If it is still not loud enough, tune the value 14 only with steps above.
The following table shows the default values of each level for Mic for Normal Mode. Max Vol. is 128 for all levels.
p/s: I wonder why level 2 to level 5 are totally messed up too.
Headset mode where we can adjust the sound volume for our headphones. You can choose to only change the value of level 6 if your ears are made of steel and always put maximum volume on headset. For normal users, it is advisable to calibrate each level using the baby steps above. Adjust the values in sph and sph2 first. Increase the value and Max Vol. in Sip if you are still not satisfied with the maximum sound.
The following table shows the default values of each level for sph and sph2 for Headset Mode. Max Vol. is 144for all levels.
This is the speaker used when we use speaker mode while calling or using messanger apps such as Wechat. For this calibration, we choose Loudspeaker Mode and tune it on sph and sph2 type. Follow the baby steps above and tune this. Increase the value and Max Vol. in Sip if you are still not satisfied with the maximum sound.
The following table shows the default values of each level for sph and sph2 for Loudspeaker Mode. Max Vol. is116 for all levels.
