It turns out that tonight was the first time after I upgraded my FP4 to Android 12 where I needed to play media over the phone loudspeaker. It does not work.
This is has worked fine on Android 11 and it still works if I play the media over Bluetooth (so it is not the media players that are at fault). Also, the phone can still ring so the loudspeaker works.
Edit: making phone calls also works.
But media sound is gone. I will greatly appreciate any help on this.
First off: somehow this problem has disappeared overnight, I suppose I should be happy now
Is the speaker working for hands-free phone calls?
I don’t know as I almost always use a BT headset or the BT in my car when making hands-free calls.
Which app are you using to play media?
I have tried the following:
Tidal (streaming from the Internet)
PlexAmp (streaming from a local server)
Poweramp (music on MicroSD card in the phone)
Various pitch pipe apps (for singing in the right key)
None of these worked yesterday evening. All of them work now.
My phone has been not been turned off or rebooted in the meantime (well over 11 hours).
And although some apps have been updated early this morning, none of those have anything to do with media sound.
