[Sennheiser HD 4.50 BTNC] Bluetooth headset not working when selecting HSP/HFP audio profile in Focal Fossa

[Stefano]

After updating the release from Ubuntu 19.10 to 20.04, the bluetooth headset doesn't work anymore when HSP/HFP profile is selected.

With Ubuntu 19.10 the headset was working, there was audio and the mic was perfect for video conferencing.

[Steps to reproduce]
1. Connect headset (used blueman to setup and connect)
1.1. When connected the system automatically selects A2DP profile
2. Start playing audio (browser or other)
3. Change profile to HSP/HFP with pavucontrol (or blueman)
4. The audio disappears and microphone is not working (no input)
5. Optionally switch back to A2DP and the audio comes back

[Expected]
When switching to HSP/HFP the audio should keep playing and the microphone should start working

[Notes]
I tried with pavucontrol to switch between profiles while playing audio from a browser.
As side note there's a led in the headset that still blinks when switching profile.

I tried deleting the pulse folder under user's profile .config without success, also reinstalled packages and did a `sudo alsa force-reload` and rebooting several times.

Note: not sure this is a duplicate of [Bug #1576559], it looks quite different since the profile changes but the headset stops working.

[Stefano (khaos86)]

Just updated Pulseaudio to version 1:13.99.1-1ubuntu3.2 and the problem persists.

[Rob Robertson (rob-rob)]

I'm experiencing this issue after upgrading to 20.04 from 19.10. My headphones are Bose QC35s. Pretty much exactly the same symptoms. Sound works well from A2DP profile. Sound stops working when HSP/HFP is selected. Works when A2DP is,again, selected.

Tried deleting the user .config profile.

There is another confirmation of this happening with QC35s on the Bose forums.

When switching from A2DP to HSP/HFP I get this log message 5 times:

This didn't initially occur after the update to 20.04 but after an update last Tuesday(-ish) (2020-05-26) I can no longer use my Motorola Escape 800 ANC headset in HSP mode. There is no apparent error when switching to HSP/HFP mode but there is no sound through the headset and the microphone does not work either.

[Simon DOUCHY (drub4n)]

Same issue here was working fine until monday for my first weekly meeting ...
Fresh install of ubuntu 20.04 today, same problem.

[Hui Wang (hui.wang)]

Just run sudo apt dist-upgrade on my ubuntu 20.04 and tested with 2 BT headsets (QC35s and harman kardon soho wireless). both a2dp and hsp/hfp worked well, both output and input worked well.

After the headset is connected, it is a2dp profile. I could change to hsp/hfp from gnome-sound-setting, both the output and input worked well with hsp/hfp profile. Or I also tested changed profile with pacmd set-card-profile 1 headset-..., it also worked well.

So for those who have this problem, what are the detailed steps to reproduce this issue?

[Pandu Rakimanputra (maspandhu)]

I also experience this issue with 2 different Brand of Bluetooth Headset:
ATH-CRK75BTH
Edifier W200BT

Problem also appears every time I switch bluetooh devices as INPUT device and OUTPUT using HEADSET Unit (HSP/HFP). Input indicator bar doesn't move and test OUTPUT doesn't produce any sound. When I tried video conferencing with my friend, he couldn't hear my voice and of course I can't hear him either.

This is fresh installation using Ubuntu 20.04 (no prior Ubuntu or other Linux distro in this laptop). A2DP mode works normal. Currently I'm using internal laptop microphone and A2DP combination for video conferencing. Just now, I ran "sudo apt dist-upgrade, some packages were updated. But still not work for HSP/HFP mode output and Bluetooth mic input.

[Allan (allan-2bc)]

I have the same issues with:
- Cowin E7 Headset
- Plugable USB-BT4LE Bluetooth dongle

[Felix Flaherty (foenx)]

Same issues with JBL E50BT!!! :-/
Only the output is working (A2DP-Profil). But that's it no matter what changes I make to config's.

- Microphone is not working (no matter what profil is chosen)
- On A2DP listening to audio is possible

[David Jeffrey (lepoetemaudit)]

I have the same with the headset that was initially reported - the Sennheiser HD 4.50 BTNC. A2DP works perfectly.

[greg matthews (odlaw)]

confirmed that I can't switch between the two modes HSP/HFP and A2DP when using Sony CH-500 bluetooth headset.

Initially it was stuck at HSP/HFP but after some messing with /etc/bluetooth/main.conf I got it to switch to A2DP but now it wont switch back and the mic never shows up.

[Michael Heller (chusti)]

same issue here with a freeVoice headset.
as soon as I switch to hsp/hfp mode audio stops working.
funny enough the beeps while changing sound volume are hearable

[Michael Heller (chusti)]

I fixed the problem for my laptop.
it looks like its a configuration issue in /etc/pulse/default.pa file.
I simply made a diff with a previous ubuntu version aka 19.10 and adjust the config (I copied the config file ) and restart pulseaudio with "systemctl --user restart pulseaudio".
and my hsp/hfp profile now works and I can use the microphone as well.

[David Jeffrey (lepoetemaudit)]

I can confirm that Michael's solution also fixed it for me. I didn't have the 19.10 config to hand so I extracted default.pa from the .deb from 19.10 as found here https://launchpad.net/ubuntu/bionic/amd64/pulseaudio/1:11.1-1ubuntu7, ran the diff, restarted Pulseaudio and the HSP/HFP profile worked immediately.

Thank you Michael!

[Corey McCandless (cmccandless)]

I am experiencing this issue as well, but don't know how to extract the 19.10 default.pa from the .deb package. Can someone who has successfully applied this solution please post which lines they changed/added?

[Michael Heller (chusti)]

@David is it sustainable in your case and works also after a power down of the machine?
unfortunately, in my case it only works when I first boot ubuntu 19.10 via live iso and reboot into installed ubuntu 20.04.
however, after a complete power down my 20.04 fails back to not working hsp/hfp mode.

[Olivier JUDITH (gnulux)]

Finally, i have the same problem on Vivobook S15 and Headset QC35 II that worked perfectly before upgrade to 20.04.
It's very annoying issue in this period of containment and remote calls.
Don't push me to switch on Windows

[Hui Wang (hui.wang)]

Maybe different machines have different root cause for this issue, for my case:

I have 3 laptops: 1 dell laptop with intel BT 8087:0aaa, 1 dell laptop with Atheros BT 0cf3:e007 and 1 lenovo laptop with intel BT 8087:0029. I have 4 BT headsets: 1 QC35 II, 1 harman kardon soho wireless, 1 sony wl-1000x and 1 plantronics Go2.

After freshly installing the ubuntu 20.04, those 4 headsets work well on both Dell laptops, in the hsp/hfp mode, both playback and recording work well.

But on the Lenovo machine, I reproduced the issue, all headsets could work in A2DP mode, couldn't output and record in hsp/hfp mode.

I ran $sudo btmon, found after switch to Synchronous connection successfully (HCI Event: Synchronous Connect Complete), the dell machines could receive the sco packets from headsets, while the lenovo machine couldn't. The difference between Lenovo and Dell machines is they have different BT host controllers. Then I debugged the bt kernel driver, found on that lenovo machine, the btusb driver could not receive the usb_isoc packets from headsets (length always equals 0).

So on my LENOVO laptop, it is highly possible this is a kernel driver or BT firmware/WiFi firmware's bug.

So if possible, you could plug in an external USB BT dongle to redo the test, let headsets connect to that dongle instead of BT hci on your laptop. Or you could run sudo btmon to check the log, if it is a synchronous connection failure or TX/RX on SCO packets failure.

This is a example log captured on my Dell machine (without hsp/hfp issue), starting capture when manually switch to hsp/hfp mode:

@ MGMT Open: btmon (privileged) version 1.14 ...

[Hui Wang (hui.wang)]

And I just did a test on that Lenovo laptop. Disable the on-board bluetooth host controller via BIOS, and plug in a usb bluetooth dongle (CSR8510 A10 0a12:0001), now the hci0 is the external usb bt dongle. And all 4 headsets could work well in hsp/hfp mode now, both playback and recording work well. And through hciconfig, I could see the sco packets number is not zero anymore.

So for my case, it is kernel driver or firmware issue instead of pulseaudio issue.

[David Jeffrey (lepoetemaudit)]

@Michael unfortunately, the fix did not persist for me through a reboot either.

[alcachi (alcachi)]

I replaced default.pa with the one extracted from the deb mentioned by @David but, in my case, it did not fixed the issue, so as @Hui said there can be several underlying issues causing the same problem.

In my case (Dell XPS13 7390) the kernel module used is btintel with device firmware: intel/ibt-20-1-3.sfi.

I have verified with btmon that when I switch from adsp to hsp/hfp it stops showing packages coming from the headset.

@Corey to extract the file you just have to run something like:

    dpkg-deb -x pulseaudio_11.1-1ubuntu7_amd64.deb pulseaudio

[Hui Wang (hui.wang)]

@alcachi,

On that problematic Lenovo machine, the kernel module used is btintel with device firmware: intel/ibt-20-1-3.sfi too. Let's wait for firmware or driver update from upstream.

[Hui Wang (hui.wang)]

It probably is a kernel driver or firmware's regression, could you run the 19.10's kernel + 19.10's firmware under 20.04 to test?

[Olivier JUDITH (gnulux)]

Hi all,

It works for me on Asus Vivobook after have applied firmware linux-firmware_1.183.2_all.deb on Ubuntu 20 on kernel 5.4.0-42-generic . Don't know how.

[Pelayo Méndez (pelayo-mendez)]

As workaround a mix between Oliver's solution and this in the duplicated thread (https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1871794/comments/25) worked for me on Ubuntu 20.04 / kernel 5.4.0-42-generic / MSI Prestige 14

I removed from my system /lib/firmware/intel/ibt* and copied /lib/firmware/intel/ibt* inside linux-firmware_1.183.2_all.deb (http://archive.ubuntu.com/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.183.2_all.deb)

Didn't have to make any changes to /etc/pulse/default.pa but reverted the audio configuration to default by removing ~/.config/pulse

[Mikko Pohja (mjpohja)]

Same issue here with Bose QC35 II and Thinkpad X1 Extreme (2nd gen).
Audio profile works just fine, but headset does not play any sound and the microphone does not get any input. It was like this already in April and currently on a fresh install of 20.04.

I tried @Pelayo Méndez's solution on my MSI Prestige 14 A10SC:

1) replaced the ibt- * drivers of version 20.04, contained in /lib/firmware/intel, with those of version 18.04
2) cleared ~ /.config/pulse

without success.

I tried to replaced /etc/pulse/default.pa too, and reboot, but without success

[dgoosens (dgoosens)]

Hard to believe there is no kernel developer impacted by this issue... Am about to have to buy a wired headset just to make calls on Teams.

[Olivier JUDITH (gnulux)]

D'ont know if that c

[Olivier JUDITH (gnulux)]

Don't know if that can help but i moved to 5.8.1 kernel . It works well with my previous workaround :
remove ibt- * from /lib/firmware/intel then copy all ibt-* from linux-firmware_1.183.2_all.deb

It works fine until an apt-upgrade installs the new latest linux-firmware 1.187.3 .

This time i do the first step again but nothing work . So i reinstalled linux-firmware 1.187.3 and i deleted all ibt-12* then update-initramfs -u -k `uname -r` .
It works now, until the next update i suppose.

This time no firmware it loaded at boot for bluetooth

Hope someone smarter than me will figure out which package did unlock the HSP/HFP profile...

This is also happening with my JBL TUNE120TWS on Ubuntu 20.04.1
Can not switch to HFP/HSP profile in a GUI-settings menu.
Sound works fine, but have nothing to pick up from in the list of inputs.
Hope this could help.

[Ben O'Steen (bosteen-gmail)]

Noticed that I couldn't use my headset mic on any apps in the past month, but the above reports are describing the same behavioural issues as I am seeing soI think I am hitting the same problem.

Using Sennheisser HD 4.40BT headphones on a System76 Gazelle. Connects default audio through headphones with the A2DP profile as expected when connecting through BT, but the Internal Microphone stays selected for input. Trying to select the HD4.4 microphone setting does nothing, and no signal of any kind comes through the input.

Switching to the HFP/HSP profile also leads to a break in audio, and after the A2DP setting is shown as unavailable until I wipe the userland pulse configs. It cuts off the audio through the headset and ends up in a bad configuration where I have to turn BT off and on again to reconnect and when it does, the configuration is stuck on HFP/HSP and in mono.

No audio through the headset mic can be picked up through any pulseaudio-enabled monitors, all showing zero input with whatever configuration or set-up I can muster.

Running Linux pop-os 5.4.0-7642-generic #46~1598628707~20.04~040157c-Ubuntu SMP Fri Aug 28 18:02:16 UTC x86_64

[bluppfisk (bluppfisk)]

Same issue. Had some promising results with pali's branch of pulseaudio which contains fixes for HSP/HFP profiles. But then a pulseaudio/kernel/idk update borked it all and I don't have the mental bandwidth to try it all again.

[jbradi (jbradi)]

Hi

Same problem with:
Ubuntu 20.04.1 LTS
HP Elite Dragonfly i7
Plantronics PLT V5200 Series

When I active PLT V5200 microphone from config window, it change HSP/HFP sound and sound stop working, micro do not work neither and if some video/audio was playing, it also stops till I change again to A2DP sound and disconnect microphone.

So, micro becomes unusable.

Regards.
J.B.

Problem has been fixed for my setup:

- Kernel: 5.4.0-55-generic
- OS: Xubuntu 20.04.01 LTS
- Machine: Lenovo ThinkPad T14

So far I haven't been able to hear how they sound with this profile and it sounds awful. So now since I did, I do not recommend using it for good quality calls.

I was able to have a workaround by following this answer and setting up ofono: https://askubuntu.com/a/1236379/295477. However, I expected it to work out of the box...

[Michael Davis (medavis)]

I'm experiencing this issue as well. On the HSP/HFP profile, the audio output comes through crystal clear, but the microphone is lost. On the A2DP profile, I get the microphone back, but the sound quality on the headphones becomes terrible... sounds like I'm on a copper phone line or bad cell signal.

[Michael Davis (medavis)]

Correction to #81, I meant to say on the A2DP I've got no microphone (as I understand it this is expected as A2DP is unidirectional) and on the HSP/HFP profile I have access to the microphone, but the audio quality is very poor and unusable.
