Android Question Playing sounds through speaker even if earphones are plugged

[Alessandro71]

I need to play a sound with the phone speaker even if the earphones are plugged in.
Currently I'm using the SoundPool Play function, but sound get played into the earphones, when the connector is plugged in.
I've found this thread

media player (and text to speech) output to phone ear speaker instead of loudspeaker

hello, i need to improve my program, a sort of to-do-list since now, my prog does this: plays ringtone to the loudspeaker through media player and the fake green and red buttons are used to redirect the user to other app pages. the user must read. now, i want the user to answer the fake...

but it seems to deal with actual phone calls, since it sets the MODE_IN_CALL parameter.
My use case is about playing sounds with no calls ongoing.

That example is not related to a phone call.

That example is not related to a phone call.

it does not seem to work: sounds are still played in the headset instead of the phone speaker: i'm going to play a little with the different modes

 

[Alessandro71]

the code in the first thread does not work (anymore?)
this thread has correct code

To me they work fine with both JavaObject and Reflector library. I attached an example.

Having a few more details and a piece of code would help us understand the problem.
For example, what version of Android does your device have?

 

[Alessandro71]

yes, because your code is

    Dim rr As Reflector
    rr.Target = rr.GetContext
    rr.Target = rr.RunMethod2("getSystemService", "audio", "java.lang.String")
    rr.RunMethod2("setMode", "3", "java.lang.int")
    rr.RunMethod2("setSpeakerphoneOn", value, "java.lang.boolean")

and it works correctly

the original thread code was

   Dim r As Reflector
   r.Target = r.GetContext
   r.Target = r.RunMethod2("getSystemService", "audio", "java.lang.String")
   Dim mode As Int
   If Value Then mode = 2 Else mode = 0
   r.RunMethod2("setMode", mode, "java.lang.int")
End Sub

and this version is not working on a Samsung A20e with Android 11

different mode and lack of setSpeakerphoneOn

Maybe a change of Android 11

 

[Alessandro71]

it looks like a change of android 11

that was my guess also

the code in the first thread does not work (anymore?)

 

[Star-Dust]

that was my guess also

I can add that I have done the tests on my XIAOMI smartphone with Android 11 and the code works correctly. I did a further test on a REALME device running Android 11

I guess it's not a change from Android 11
