I've got a Bluetooth headset (Sony WH-1000XM3) which works perfectly with PulseAudio as long as I only use it as an output device. Changing the Bluetooth profile in pavucontrol works for everything (SBC, LDAC, aptX HD, aptX and AAC) except HSP/HFP. PulseAudio outputs the following error when this happens:

I: [pulseaudio] protocol-native.c: Application "PulseAudio-Lautstärkeregler" requests card profile change. card = bluez_card.38_18_4C_6D_C9_22, profile = headset_head_unit

On start also

appears in the log.

I'm on Fedora 31 and have the following package versions

My bluetooth device

Bus 001 Device 002: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)

EDIT: No news, yet (ordered a new dongle, but that one has exactly the same ID and name), but this thread reports the same for Ubuntu.

  • Just to clarify, when you change your output configuration to "Headset Head Unit (HSP/HFP)" is when you get issues correct? I have your setup and I had issues until I did the update to the most recent Sony's Firmware version. From time to time, I need to remove the device from the Bluetooth devices, to be able to connect again correctly. – Nuno Dio Mar 24 '20 at 21:49
  • Exactly. I'm on the latest update, I just checked, but thanks for the suggestion, woudn't have thought of that! Removing and reconnecting doesn't help ... with "connect again correctly" you mean getting a connection at all? Or the same problem as mine? – Daniel Hauck Mar 24 '20 at 22:47
  • It's simply going to Settings>Bluetooth>Click on the WH-1000 Device> Click on Red Button "Remove Device" then, Disable Bluetooth> Enable Bluetooth > Connect to WH-1000 Device. I know this is not a very advanced solution, but sometimes when I got weird behavior I do this and it comes back to normal. Just to mention... I just realized that you have installed the package **pulseaudio-module-bluetooth-freeworld.x86_64 1.3-4.fc31 @rpmfusion-free-update** Do you really need this? I don't use anything from rpmfusion at all. – Nuno Dio Mar 24 '20 at 23:05
  • That's would I did, but it didn't change anything. I need **pulseaudio-module-bluetooth-freeworld** for the LDAC, aptX etc. support. – Daniel Hauck Mar 24 '20 at 23:23
  • I just tried without this package and the normal **pulseaudio-module-bluetooth** instead, but this led to exactly the same behaviour. – Daniel Hauck Mar 24 '20 at 23:25
  • It works on my laptop, so could it be that the bluetooth adapter has to support it? – Daniel Hauck Mar 24 '20 at 23:43
  • I really don't know the answer to your question. My BT device is integrated with the laptop. ```Vendor: usb 0x8087 "Intel Corp." Device: usb 0x0a2b``` – Nuno Dio Mar 24 '20 at 23:58
  • Does this seem related to this bug?: **Sound is not coming out on connected bluetooth device** https://bugzilla.redhat.com/show_bug.cgi?id=1814556 – batisteo Mar 26 '20 at 18:52
  • I have the same problem in Ubuntu 18.04. Any progress on this ? – Paul Praet Apr 26 '20 at 14:22
  • It looks like it's my bluetooth adapter. My laptop with exactly the same software versions works as expected. – Daniel Hauck Apr 27 '20 at 15:02
  • @DanielHauck is there a workaround for it? My brand new XPS 13 (9300) has the same problem. – bluppfisk May 13 '20 at 16:34
  • (If it's any help, I've just dualbooted into Windows where I noticed the same problem. However, a new Bluetooth driver was available and after installing that and rebooting, I could use my WH-1000XM3 with the laptop). No luck on Linux yet (despite kernel 5.7 rc5) – bluppfisk May 13 '20 at 17:28
  • @bluppfisk Not that I know of ... I also just got a brand new Bluetooth (a cheap Logitech one), but no luck with that one either :-( – Daniel Hauck May 31 '20 at 23:30
  • Hello all, you may want to check Pali's work on Pulseaudio. I've been able to use his version to use my Bluetooth headset in HSP/HFP mode even if it's not perfect. https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/merge_requests/288 – bluppfisk Jun 02 '20 at 07:39
  • I have a similar issue in Arch Linux. Pavucontrol says HSP/HFP is unavailable for a JBL Live400BT. The headset specs say it has support, although. Tried `pulseaudio-hsphfpd` from AUR but it didn't work. – paulodiovani Aug 10 '20 at 20:52
  • @paulodiovani What bluetooth adapter do you use? – Daniel Hauck Aug 11 '20 at 21:12
  • I believe it comes with my Wireless card, listed on `lspci` as `Qualcomm Atheros QCA6174 802.11ac` – paulodiovani Aug 11 '20 at 23:14
  • Does this answer your question? [how to use bluetooth device with HSP/HFP profile using pulseaudio >=6 and bluez >= 5.24](https://unix.stackexchange.com/questions/341776/how-to-use-bluetooth-device-with-hsp-hfp-profile-using-pulseaudio-6-and-bluez) – αғsнιη May 23 '21 at 14:58

    The linked page explicitely says "These steps are here for archival purposes only. Firmware errors on Linux regarding the Bluetooth adapter have no impact on Bluetooth functionality in modern Linux distros". And the ["new" solution](https://kb.plugable.com/questions/680389) only updates to a newer BlueZ version. The problem is not relvant anymore though as Fedora now uses pipewire and with that it works. – Daniel Hauck May 24 '21 at 17:34

I have a USB Bluetooth dongle that uses the same chipset and was able to get it working on Raspbian buster. A2DP support seems to be pretty good out of the box, but you need HSP/HFP support if you are using a headset. The following link states something like this:

https://hackaday.io/project/165208-an-old-rotary-phone-as-bluetooth-set/log/162491-setting-up-the-bluetooth

Furthermore, if you find that your headset supports the HFP profile, you will need to install Ofono, as stated in the PulseAudio documentation following:

https://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/Bluetooth/

I've generalized the scripts that I have, and have posted a link to the GitHub repo:

The problem is solved for me by using pipewire (which is used by default in newer Fedora versions anyways).
