Thankyou.
The cable worked fine before and works fine with other phones. My headphones are also quite on this phone and were previously ok. I do not have an amp nor another speaker but this speaker worked well with Sailfish 2.x and 3.x
I tried audio output switcher as suggested and going through all the choices it did not help in this matter, though playing through the phone speaker and “headset” external speaker the phone speaker drowns out the small sounds from the external speaker which should be much, much louder.
I cannot connect via bluetooth to test as bluetooth isn’t working anymore in 4.1
