[Bluetooth] No audio output/input in HSP/HFP mode

[Gavin Lin]

I'm testing with Sony bluetooth headset SBH20, works fine in A2DP profile, but I can't get audio input and output work in HSP/HFP profile.

[Reproduce steps]
1. Scan and pair BT headset in Bluetooth setting
2. Switch to HSP/HFP profile in Sound setting
3. Test sound output/input

Thank you for taking the time to report this bug and helping to make Ubuntu better. This particular bug has already been reported and is a duplicate of bug 1576559, so it is being marked as such. Please look at the other bug report to see if there is any missing information that you can provide, or to see if there is a workaround for the bug. Additionally, any further discussion regarding the bug should occur in the other report. Feel free to continue to report any other bugs you may find.

[Daniel van Vugt (vanvugt)]

This is a duplicate of bug 1576559, even if the error and reason has changed over the years. Everyone experiencing this problem should be discussing it in the same bug.

[Rob Robertson (rob-rob)]

This is not a duplicate of bug 1576559. It is a duplicate of #1878194

[Daniel van Vugt (vanvugt)]

If that was true then bug 1878194 would be a duplicate of this one because this one is older.

[Javier Paniagua Laconich (jpaniagualaconich)]

Correct.
This is not a duplicate of #1576559.
#1878194 is a duplicate of this one.

But all the action is on #1878194, so let's make that one the original bug.

[Daniel van Vugt (vanvugt)]

It's not that much "action". We can make this the main bug...

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

I am getting the same issue with a new device. Everything works fine on one BT USB, but the intel one fails. It is a PCIe card with Intel AX200 Wifi+BT, with BT being passed through a USB header.

[Fmstrat (fmstrat)]

I should also note, if it helps, that when this BT device is installed on the system, using the hotkeys to adjust volume on my keyboard no longer works.

[Hui Wang (hui.wang)]

@Fmstrat,

In your case, It looks like the driver for BT module on AX200 or the firmware intel/ibt-20-1-3.sfi has some problem, could yo please submit this bug to upstream

[yossisynett (yossisynett)]

@hui.wang, how do we submit the bug to upstream?

[Executenor (nicktelindert)]

I found out what the problem is, the wrong firmware gets loaded. It load the firmware for the ax201 instead of ax200.

[Hui Wang (hui.wang)]

@Executenor,

what firmware is for ax201 and what firmware is for ax200?

thx.

[Executenor (nicktelindert)]

version 48 is for AX201 AND version 46 is for ax200.

[Hui Wang (hui.wang)]

Thansk, the hardware ax200 will load ibt-20-1-3.ddc and ibt-20-1-3.sfi, do you mean the ibt-20-1-3 is version 48 or the ibt-20-1-3 has version 46 and 48?

[Executenor (nicktelindert)]

I booted up my laptop today and hsp/hfp mode failed again. So my idea about the firmware seems to be wrong. So i was wrong about that.

[Executenor (nicktelindert)]

I booted a live image of 20.10 and their my bluetooth does work. I also downloaded a version of 20.04.1 which also worked fine.

[Executenor (nicktelindert)]

I have got it working with the liquorix kernel and updated firmware, the biggest issue seems to be that the ibt firmware does not get loaded.

[yossisynett (yossisynett)]

Thanks for the tip, also got this working with the liquorix kernel but didn't have to update the firmware - used the current version in ubuntu 20.04

[Executenor (nicktelindert)]

After booting the liquorix kernel the normal kernel started working too. Although with updated firmware. The difference is that the firmware is loading while before it didn't load at all.

[tim474 (tim474)]

Same problem, liquorix didn't help.

Headset Afresshokz Air.

It works as HSP on Fedora with kernel 5.6

[tim474 (tim474)]

Bluetooth device is 8087:0aaa

HSP works on the same device with ubuntu 18.04 with OEM kernel (as I remember 5.0)

[tim474 (tim474)]

PLEASE HELP!!! ANY WORKAROUND PLEASE!!!

[tim474 (tim474)]

It seems that I have found the workaround. I copied /lib/firmware/intel/ibt* from ubuntu 18.04 to 20.04

[lima (lima25)]

Above workaround with older ibt* files does not work on Ubuntu 20.04.1 LTS on Elitebook 840 G6, Bluetooth devices:
Samsung HM1350
Sony WH-CH700N

[Iain (ironpants)]

HSP/HFP does not work on Ubuntu 20.04 with Sony WI-1000X. A2DP does work (output) but as soon as I switch to HSP/HFP then I loose bluetooth audio (input and output). Ran Ubuntu 18.04 from a live USB and HSP/HFP did work so something has changed between 18.04 and 20.04.

[newsworthy39 (newsworthy39)]

Same problem here, Sone WH-1000MX2, ubuntu 20.04.1 LTS, Linux 5.4.0-45-generic. AD2P works, however as soon as i switch to HSP/HFP then i loose bluetooth audio. Worked in Ubuntu 18 LTS.

[Executenor (nicktelindert)]

I use a Sony WH-1000MX2 too, and after an update my bluetooth broke again.

Status changed to 'Confirmed' because the bug affects multiple users.

[Luke Renaud (luke-renaud)]

From what I can gather this is not a function of the headset or Bluetooth device, but it's a function of firmware differences in the host side Bluetooth adapters.

For example, I have a Sony WH-1000MX3.

I have a USB dongle adapter that does not work in the HSP/HFP mode. When selecting the mode the active profile throws various errors then returns to the "off" PulseAudio/ALSA profile.

I also have an Intel Bluetooth/WiFi 802.11ac card (Bluetooth is on the USB bus), that does support the HSP/HFP mode, abet with noticeably reduced audio quality. I think there is a separate bug in launchpad tracking the audio quality issues of that mode though.

- Dell XPS 13 7390 Developer Edition
- SteelSeries Arctis Pro Wireless

[Executenor (nicktelindert)]

Ok, all these devices have intel wireless and use btintel together with btusb. And i am also pretty sure it has something to do with the firmware not loading. Also this bug has been reported on April the 9th this year and i don't see anyone working on this. And we already have a point release. Why is this not getting any attention? At least give us a status update. Many people work at home now and use bluetooth headphones for Slack or Skype etc. We bought company laptops with 20.04 LTS preinstalled and we all had to downgrade them to make them usable for working at home.

[Javier Paniagua Laconich (jpaniagualaconich)]

I'm on 20.10 Groovy Beta and, after today's kernel + linux-firmware update, HFP/HSP is working on my dell xps 13 9380.

It stopped working since 20.04, it wasn't working with all previous kernel/linux-firmware versions in 20.10. Today it's finally back.

That is weird that laptop does not have a intel bluetooth/wifi chip? I own one too as a private laptop and it has a qualcomm that should not be affected by this bug. Can you please post which chipset is has? Maybe Dell released one with an intel chipset too.

[Ranjan (ranjan-purbey)]

Yes, on 20.10 beta the bug seems to have been fixed

[Javier Paniagua Laconich (jpaniagualaconich)]

@nicktelindert

you're right. I was so happy that I misidentified my own notebook. It's the one that came right after the 9380: the 7390 (not the 2-in-1) with the dreaded intel bluetooth/wifi killer ax200.

[Executenor (nicktelindert)]

@Javier Ah ok that makes sense, i hope it is really fixed with ubuntu 20.10 then it could be used with the a new hwe for ubuntu 20.04.

[smurf (luca-dgh)]

I have the same problem with a fresh 20.04.1 install, kernel 5.4.0.52, Huawei laptop with Ryzen 5, Realtek BT (I tried as well with a tp-link dongle).

Bus 003 Device 002: ID 1358:c123 Realtek Bluetooth Radio

In my case A2DP is working, but I can't switch to HFP/HSP from Bluetooth device manager, nor from pulseaudio.

[Marco Giovinazzi (marco-giovinazzi)]

Same problem using Aeropex by AfterShokz (AVRCP) headset on 20.04 (xps9310).

Quick-and-dirty workaround:
- download the 1.190 firmware package (http://mirrors.edge.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.190.tar.gz)
- copy the relevant ibt firmware and parameters (sfi, ddc) to /usr/lib/firmware/intel (ibt-19-0-4 in my case) - backup of the old files highly recommended ;)
- reboot, reconnect.

My headset is now working both in A2DP and HFP/HSP modes.

[Hui Wang (hui.wang)]

@Marco,

What the bluetooth module on your machine? Could you please upload the vendor ID:device ID like #49?

Hi all,

throwing in my experience:
Sony WH-H910N,
ThinkPad P1 Gen 2,
Bus 001 Device 007: ID 8087:0029 Intel Corp.

Worked under 18.04
When upgraded to 20.04 rcX (before it was released), still kept working. Not much later - already on released 20.04 - with a fw/kernel/whatever upgrade it stopped working in HSP/HFP mode.

Since there were errors in dmesg related to the FW loading, I downloaded upstream FW from git, put them under /lib/firmware, and added a dpkg-diversion for the package provided versions, so that it survives an upgrade:
dpkg-divert --list | grep ibt
local diversion of /lib/firmware/intel/ibt-20-1-3.sfi to /lib/firmware/intel/ibt-20-1-3.sfi.dist
local diversion of /lib/firmware/intel/ibt-20-1-3.ddc to /lib/firmware/intel/ibt-20-1-3.ddc.dist

Headphones Sony WH-H910N do work out of the box on a different system with the same distro - with BT HW 8087:0a2a.

[Hui Wang (hui.wang)]

@Marco,

I just have a lenovo laptop with the usb bluetooth module 8087:0026, I will test if it could work on my laptop.

@Istvan,

Yes, most of this kind of issues are in the bluetooth firmware or kernel driver, and nearly has nothing to do with pulseaudio.

[Hui Wang (hui.wang)]

For those who are using the laptop with Intel BT module 8087:0029:

The firmware in the current 20.04 is: md5sum 8cadd1fa93ab9790f61165f384466b0d ibt-20-1-3.sfi

The firmware in the current 20.10 is: md5sum a2ebb8594804b5230a406b536804988c ibt-20-1-3.sfi

The hsp/hfp could work in the 20.10 but couldn't work in the current 20.04 due to the firmware difference.

There are 3 new commits applied to 20.10 firmware:

@Marco

On my machine with BT moudle 8087:0026, I reproduced the problem, and replaced with 20.10 firmware ibt-19-0-4.sfi, but still could not work in hsp/hfp mode.

What I found is the bt driver can't receive the SCO packet, the returned packet length is always 0.

And if the bt headset can't work in the hsp/hfp mode, please run hci config, if the output like below (RX bytes: sco:0 TX bytes: sco:1), that means the bt driver can't receive SCO packets, as a result the headset can't work in hsp/hfp mode since hsp/hfp mode depends on SCO link.

[Benny Prange (bennypi)]

@Marco and Hui Wang

My Dell Latitude 5411 also contains an Intel BT Module 8087:0026. I can also reproduce the problem with my Sony WH-CH700N headphones. A2DP is fine, HSP/HFP is broken.

I also tried Marco's fix and copied the newer firmware (https://launchpad.net/ubuntu/+source/linux-firmware/1.190) for ibt-19-0-4, but just like Hui Wang the problem still exists. I can also confirm the hciconfig behaviour, every time I switch to HSP/HFP, the TX sco counter increases by one, but the RX sco counter stays at 0.

[Hui Wang (hui.wang)]

If the bluetooth module is 8087:0029 or 8087:0026, the firmware in the 20.04 has some problem, we need to update the firmware, and I found the most import is *.ddc instead of *.sfi,

For 8087:0029, please update ibt-20-1-3.sfi and ibt-20-1-3.ddc from 20.10 or latest upstream

For 8087:0026, please update ibt-19-0-4.sfi and ibt-19-0-4.ddc from 20.10 or latest upstream

After update, please poweroff the machine (not reboot), this could guarantee the bt driver will reload the firmware (sfi and ddc), then power on the machine, test the hsp/hfp mode.

I have tested, after update the ddc, hsp/hfp could work with 8087:0029 and 8087:0026 now.

[Benny Prange (bennypi)]

@Hui Wang

After I powered off the machine instead of a reboot, the HSP/HFP mode is now working.

However there are two things to note, that might be related to this problem:

1. In the sound settings menu (I'm using Linux Mint Ulyana) I cannot play a test sound in HSP/HFP mode, only in A2DP mode.
2. The sound quality is significantly worse when using HSP/HFP. It really sounds like using a telephone / landline connection. As soon as I switch to A2DP, the sound ist normal again.

[Marco Giovinazzi (marco-giovinazzi)]

@Hui: thanks for the update :)

@Benny: the issue with pulseaudio and bt sound quality is a neverending story... e.g.:

https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/issues/776

https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1838151

I'm considering an USB audio adapter (as someone is suggesting in the other threads) since it's almost impossible to have a decent conversation using my laptop and my bt headset...

[smurf (luca-dgh)]

Ok, Intel hardware has a solution, but other hardware?
I have Realtek, has mentioned above, and the problem persist.

[Hui Wang (hui.wang)]

@smurf,

After you switch the bt profile to hsp/hfp mode, please run hciconfig, let us see if the bt driver could recevie the sco packets?

And BTW, what is your WiFi module's name (BT and WiFi usually co-exist on a physical module), I will check if there is a machine with the same module in our office.

[KT (arsenalis)]

I would like to report back that on Ubuntu 20.04 with Intel AX200 network card (8087:0029), I resolved this issue by following @Hui Wang's instruction

ibt-20-1-3.sfi and ibt-20-1-3.ddc from 20.10 driver

HSP/HSF was greyed out before but is now available and functioning after powering off and on again.

[smurf (luca-dgh)]

@Hui Wang,
actually I can't switch to hsp/hfp mode.
In BlueMan device window, if I try to switch profile I receive an error (the red bar at window bottom) and in Pulseaudio I don't have the option to switch.
Furthermore, in Blueman window manager, when I connect the headphone I see an orange button with an orange bar above, a green button with no bar above and a blue button with a blue bar above.
If I use a tp-link dongle I see the green bar as well.
On the same laptop I have windows 10 (dual boot) and there the headphone microphone works fine.

Here lspci and lusb output,let me know if you need some more info.

[Hui Wang (hui.wang)]

@smurf,

OK, got your wifi's type, it is rtl8822ce, I will check if I could find a machine with this Wifi chip in the office.

BTW, you could raise your issue to https://github.com/rtlwifi-linux too, and I found there is a driver specific to 8822ce: https://github.com/rtlwifi-linux/rtk_wifi_driver_rtl8822ce

[smurf (luca-dgh)]

ok, but what about that "Maxxter wireless receiver"?
I don't understand: my laptop has 2 pieces of hardware to manage the wi-fi?

[smurf (luca-dgh)]

@Hui Wang,
I tried to access https://github.com/rtlwifi-linux, but I didn't find where to report my issue.

[Hui Wang (hui.wang)]

I don't know, maybe it is a wireless mouse receiver?

[Hui Wang (hui.wang)]

https://github.com/rtlwifi-linux/rtlwifi-next/issues

[smurf (luca-dgh)]

ok, got it, thx a lot.

[mistrani (mistrani)]

solved from me upgrading from 20.04 to 20.10

[smurf (luca-dgh)]

@Hui Wang,
about the new driver in git repository.
I downloaded the source and compiled it, but the readme file is empty and I don't know the steps to install it and insert in dkms. I wrote an issue for this in git repository.
Could you help me?

[Hui Wang (hui.wang)]

@smurf,

What is generated after building? If it is *.deb file, just need to run 'sudo dpkg -i *.deb; reboot'

[Raknu (santiago-azpiazu)]

Also solved upgrading from 20.04LTS to 20.10.
I have a JBL TUNE500BT working now.

[smurf (luca-dgh)]

@Hui Wang,
no is not a package, the Make generated *.so or something like that

[smurf (luca-dgh)]

Please please, I'll apreciate a lot any kind of help.

[Michael Heller (chusti)]

Nice to see it works for 20.10.
however, I'd like to keep on the LTS version and expect to get a fix soon.

[Anton Viktorov (latonita)]

ubuntu 20.04, kernel Linux 5.4.0-52-generic
samsung galaxy buds, cant switch to hsp/hfp
thinkpad x1 carbon. laptop has intel BT 8087:0a2b,
/lib/firmware/intel/ibt-12-16.sfi is used.

tried to get "new" from here https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/intel but it has same fw file as i have on my system

[smurf (luca-dgh)]

Ok, I upgraded to 20.10, but in my case there are no changes, I see exactly the same behavior than in 20.04 .
I would appreciate a lot a bit of help.

[Hui Wang (hui.wang)]

@smurf,

I heard this wifi+bt module needs to install a dkms. I will ask my colleague about it.

[Hui Wang (hui.wang)]

@smurf,

My colleague told me that: sudo apt install rtl8821ce-dkms;reboot

if it doesn't work, you could remove it by sudo dpkg -P

[smurf (luca-dgh)]

@Hui Wang
Thank you so much for your help.
Unfortunately now I got another problem. I upgraded to Ubuntu 20.10 with kernel 5.8.0-28 and now the driver doesn't compile, there is a fatal error, on 20.04 with kernel 5.4.0.53 there was no errors.
I opened an issue here https://github.com/rtlwifi-linux/rtlwifi-next/issues/18 , but honestly I don't know if someone reads that forum.

[Hui Wang (hui.wang)]

The Intel bluetooth firmware will be upgraded with this bug #1905214

[Kenneth Koski (knkski)]

Thanks @hui.wang. Upgrading to Groovy didn't fix the issue for me with an AX200 card, but installing rtl8821ce-dkms made it work great.

[smurf (luca-dgh)]

@Hui Wang
sudo apt install rtl8821ce-dkms didn't the magic in my case.
hsp/hfp is still not working. I disabled Secure Boot on my laptop, I hope is not a problem.

[Hui Wang (hui.wang)]

@smurf,

after you change to hsp/hfp mode and it fails, please run hciconfig -a > hcilog.txt and upload it.

[smurf (luca-dgh)]

@Hui Wang
hsp/hfp mode doesn't fail, because it can't be activated.
In Blueman it says that it's impossible to switch the profile.
In Pulseaudio I have no options.

[smurf (luca-dgh)]

Anyway, this is the output of hciconfig -a after I tried to switch to hsp/hfp mode from BlueMan Manager.

I had to reinstall Ubuntu 20.04 with kernel 5.4.0-56 because on 20.10 with kernel 5.8.0-28 the wifi was very unstable.

[Jonah Libster (jalibsterattucows)]

Cannot use Microphone at all because when I switch to HSP/HSF mode the Microphone has no input and the speakers stop working. I tried installing Ofono which resulted in the Microphone working as a "speaker" (got sound levels) and the speakers not working at all when attempting to use HSP/HSF mode.Here are the hardware/Os basic details.

[Sherebyah Tisbi (sherebiahtishbi)]

Confirm this issue with my Logitech H800 headset and also with Bose Mini II Soundlink. I hear audio successfully on both devices irrespective of A2DP or HSP/HSF. But microphone doesn't work on either mode.

[Vedprakash Upraity (vedupraity)]

I am facing the same problem with Ubuntu 20.04.1 LTS, using Sennheiser HD450 BT. I can switch between A2DP and HSP profiles, A2DP works great for music. When I switch to HSP, it reduces audio quality and sounds like a telephone and the mic is not working at all.

Same issue for me: A2DP sink, sound is clear. If it set it as HFP, no sound and no mic.

Also I notice that the main volume control doesn't affect the volume (it remains the same and I have to change the volume by using the minus/plus in the device)

PipeWire didn't solve my issue.
