The clue here to me is "the audio was coming out of my phone normally;" This sounds like the jack in the phone didn't switch off the audio to the phone's speakers. There are many reasons for this from a too small jack, wrong jack to a failed jack in the phone.
At no point does this tell us exactly what it is but I do try a headphone to see if the headphone works next. If the headphone work I look at the plugs and pull out my micrometer to see if the one that works is fatter and count the rings on the plug.
I admit this won't be taken as helpful by a few members but I'll try anyway.
Hello, I'm using a usb adapter, which has both mic and headset 3.5 jacks, and with a male to male aux cable, I connected one into the phone, and one into the mic usb jack, then on the computer (windows 10) I went into the audio settings, and then recording, then enabled the microphone usb adapter, then clicked properties, and selected "listen";
Then I played audio on my phone, but the only thing I heard through the laptop speakers was a high pitched beeping noise, and the audio was coming out of my phone normally;
Then I tried plugging in a headset on my phone, and the sound came through fine on the headset, so I tried my other phone, which is a microsoft lumia 640, and it worked straight away, and the quality of sound was perfect too;
Can anyone give me any tips on solving this problem, why one phone works and the other phone doesn't work, the android phone is a nokia 6.1 updated to pie, one version, with the latest updates
