Does anybody know of any tricks needed to get audio to go out through an ongoing phone call? Everything in my setup looks good, with all the right devices and settings in bluetoothctl, pavucontrol (including correct headset/handsfree profiles) and I can hear the caller, but they are only getting silence from my end. I am using the pulseaudio asynchronous API, which works well enough playing through speakers but I can't get sound through the telephone (an Android device, which works perfectly well with my car's headset). bluez5: 5.51 ofono: 1.30 pulseaudio: 13.0 debian: 10 (stable) linux: 5.3.0 I'm quite desperate to get this sorted, so if it is an unsolved problem perhaps some pointers to where the issue might be will help me to help you debug the situation? As you see from the updatedness of the packages, I have built them all from source and can dig if necessary. Thanks in advance for any help, Dale
