Hi everyone, small progress report :
I tried the pipewire trick and it didn't work out for me, while it initially seemed to work: auto switch to the HSP/HPF profile didn't work and after a manual switch the headset would drop out during a conversation. I reverted to pulseaudio and invested a bit more time, now I am _almost_ there : I had to add the following to ~/.config/pulse/default.pa .include /etc/pulse/default.pa .nofail unload-module module-bluetooth-policy .fail .ifexists module-bluetooth-policy.so load-module module-bluetooth-policy auto_switch=2 .endif .ifexists module-bluetooth-discover.so load-module module-bluetooth-discover .endif to get the autoswitch to work. I am happy to report that in slack (from snap) the audio now behaves just right and friends tell me I no longer sound like a robot. Unfortunately this still doesn't work with zoom and there seems to be multiple issues. They probably come from zoom itself but I am unsure what to report to them. according to https://gavv.github.io/articles/pulseaudio-under-the- hood/#autodetecting-properties it should be possible to make pulseaudio understand that it has to switch profiles by changing /usr/share/applications/Zoom.desktop and adding Telephony to the categories. I have not been able to make this work without auto_switch=2 Here are two scenarios that fail: after a fresh boot (so all the stars are aligned), start zoom, create a new meeting, start the recording, say a few words, stop the recording, stop the meeting, open the resulting audio or video file the sound is bad when it is expected to be good. After a fresh boot (so all the stars are aligned), start zoom, go to settings-> audio, after doing this my headset is non functional and I must shut it down and start it back up to restore functionality. can someone help me determine what zoom is doing wrong ? I will also try a few other apps in the coming weeks -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1838151 Title: Poor quality audio with modern Bluetooth headsets in HSP/HFP. Missing wide band speech support (Bluetooth A2DP codecs). Status in PulseAudio: Fix Released Status in bluez package in Ubuntu: Fix Released Status in linux package in Ubuntu: Fix Released Status in pulseaudio package in Ubuntu: Fix Released Status in Arch Linux: New Bug description: Bluetooth HSP/HFP audio quality is poor on Ubuntu comparative to all other major platforms (Windows, MacOS, ChromeOS, Android, iOS). Modern Bluetooth headsets (such as the Bose QC series headphones, many others) are capable of using HFP 1.6 with mSBC 16kHz audio encoding. As it currently stands, Ubuntu defaults to only supporting HSP headsets using 8kHz CVSD, and is incapable of supporting HFP 1.6 at this time. The ChromiumOS team recently tackled this issue - https://bugs.chromium.org/p/chromium/issues/detail?id=843048 Their efforts may assist in bringing this to Ubuntu, however it appears that there are quite a lot of differences considering they have developed their own audio server solution etc. The Bluetooth Telephony Working Group published the HFP 1.6 spec in May 2011 - https://www.bluetooth.org/docman/handlers/downloaddoc.ashx?doc_id=238193 Patches have been proposed in the past for this issue to the kernel and PulseAudio: PulseAudio: https://patchwork.freedesktop.org/patch/245272/ Kernel: https://www.spinics.net/lists/linux-bluetooth/msg76982.html It appears that the Chromium OS team applied the same kernel patch: https://chromium.googlesource.com/chromiumos/third_party/kernel/+/77dd0cb94c1713a8a12f6e392955dfa64c430e54 ProblemType: Bug DistroRelease: Ubuntu 19.04 Package: pulseaudio 1:12.2-2ubuntu3 ProcVersionSignature: Ubuntu 5.0.0-20.21-generic 5.0.8 Uname: Linux 5.0.0-20-generic x86_64 ApportVersion: 2.20.10-0ubuntu27.1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: jnappi 2777 F.... pulseaudio CurrentDesktop: ubuntu:GNOME Date: Sat Jul 27 11:08:29 2019 EcryptfsInUse: Yes InstallationDate: Installed on 2017-11-04 (629 days ago) InstallationMedia: Ubuntu 17.10 "Artful Aardvark" - Release amd64 (20171018) ProcEnviron: PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_US.UTF-8 SHELL=/bin/bash SourcePackage: pulseaudio UpgradeStatus: Upgraded to disco on 2019-07-18 (9 days ago) dmi.bios.date: 06/07/2016 dmi.bios.vendor: LENOVO dmi.bios.version: R07ET67W (2.07 ) dmi.board.asset.tag: Not Available dmi.board.name: 20FW000TUS dmi.board.vendor: LENOVO dmi.board.version: SDK0J40705 WIN dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: None dmi.modalias: dmi:bvnLENOVO:bvrR07ET67W(2.07):bd06/07/2016:svnLENOVO:pn20FW000TUS:pvrThinkPadT460p:rvnLENOVO:rn20FW000TUS:rvrSDK0J40705WIN:cvnLENOVO:ct10:cvrNone: dmi.product.family: ThinkPad T460p dmi.product.name: 20FW000TUS dmi.product.sku: LENOVO_MT_20FW_BU_Think_FM_ThinkPad T460p dmi.product.version: ThinkPad T460p dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/pulseaudio/+bug/1838151/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
