Re: Bluetooth headset HSP/HFP sound not working but microphone is

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


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/` 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/` 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:

  1. HSP/HFP mode with microphone & sound
  2. 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
