We will need quite a bit more information to help you, like btmon, journal of the components involved (bluetoothd, pulseaudio and ofono). If I got it right that is the audio path of your mic -> loopback -> bluetooth-src -> sco socket -> hci -> usb iso endpoint that is not working? There can be quite many things wrong actually, for the mic being muted to the usb endpoint not working, the later is not uncommon but you did hear the other side of the call so maybe that is not it. > Thanks in advance for any help, > Dale > > -- Luiz Augusto von Dentz
