    Dear all,

        
        I've managed to solve my Bluetooth issue. My headset is now
        working both in HSP/HFP and A2DP (LDAC) mode. I did reinstall
        all dependencies of my bluetooth setup:
    ```

      sudo apt-get update

        sudo apt-get purge bluez libldac pulseaudio-modules-bt # Remove packages

        sudo apt-get autoremove # Cleanup

        sudo apt-get reinstall -y libfdk-aac-dev libavcodec-dev
        libpulse-dev libdbus-1-dev libsbc-dev libltdl-dev
        libbluetooth-dev # Renistall as some
          of these cannot be purged

        sudo apt-get install bluez libldac pulseaudio-modules-bt

        sudo reboot # Might not be nessecary

        ```
    And changed settings in `sudo
        gedit /etc/pulse/default.pa`
        according to the manual of `pulseaudio-modules-bt`.

        I have a single remaining question, how to reset all audio
        related configuration files? I tried

        ```

        sudo apt-cache pkgnames pulse |xargs -n 1 sudo apt-get -o
        Dpkg::Options::="--force-confmiss"
        install --reinstall

      ```

      
    But apparently I did not reset all my
        configuration files, afterall `/etc/pulse/default.pa`
        did still have some edits afterwards.

        I cannot `purge` pulseaudio either, as it is a prerequisite of
        ao gnome (ubuntu flavour).

        What is the best way of resetting al user and system config
        files?

      
    Kind regards,

        Bram Lagerweij

      Dear pulseaudio,
      I've, for year's, been happily
        working with pulseaudio on ubuntu. Recently an issue appeared
        with the combination with my headset Sony WH-H900N. It used to
        work in the following two profiles:
      
        HSP/HFP mode with microphone & sound

        
        A2DP for high quality sound only (I combine this with an
          LDAC profile)
      
      I'm not sure since when, but I'm profile 1 is not working any
        more. The microphone is, but the sound does not come through. I
        do hear more static when it switches to the HSP/HFP profile but
        nothing that I play gets to sound from the headset. The exact
        problem, and the related issue search is documented as askubuntu.
        Do you know what is wrong and how to fix it? Did anything
        regarding HSP/HFP change on the pulseaudio side. Or could you
        help me getting to the exact cause of the problem?

      
      Kind Regards,

        Bram Lagerweij
