[Bug 1133165] Re: bluetooth headset pairs but audio input and output do not work


I have the same bluetooth device and just purchased a bluetooth headset,
expecting HSP/HFP to work. I saw bug 1065400, but I've got no idea where
to find the firmware for my device :/

  bluetooth headset pairs but audio input and output do not work

Status in “bluez” package in Ubuntu:

Bug description:
  Bluetooth seems to be working in that I can pair a headset with the
  computer, however, audio output and input do not work via bluetooth.

  When trying, there appears to be NO input at all, and test sounds are
  not heard via the headset (though they do work via the internal audio
  and headphone jack, and the headset has been successfully used on
  other systems without issue).
