Ever since I switched to linux I have been encountering various issues with my Bose QC35 II headset.
I used it extensively on my mac book pro before, here is the behaviour I was used to: - upon connecting the headset the sound streams where automatically redirected to it - upon starting a visio conference call (meet.google.com on chrome and firefox, skype, jitsi, slack) the built-in microphone would activate automatically and I don't remember lowered sound quality (as in noone ever told me I sounded like a robot even after switching from builtin mike to headset mike). - upon disconnecting, spotify would pause automatically (which avoids the sudden "music blasting off the laptop speaker" when the headset runs out of battery :) On ubuntu 20.04, after encountering various issues, I am in a state where it's **almost** working: - for playback on connecting it works just fine - for visio conferencing, without custom configuration pulseaudio systematically prefers the laptop microphone over the BT microphone, I can enable it but I have to manually select it in gnome settings, sometimes within the app itself. When switching from built-in laptop microphone to headset microphone, multiple interlocutors reported I suddenly sounded like a robot. - upon disconnecting, spotify does not pause automatically, I have learned to make sure the laptop speakers are muted before disconnecting or on low battery warnings from the headset. I read through a lot of material on pulseaudio lately and I think this could be configured though a policy (either by loading one that exists or by creating an additional one) According to https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/508522/comments/39, with the default configuration, autoswitch shoudl trigger when the calling app attempts to record with media.role=phone. I haven't been able to make this work on ubuntu 20.04, with - snap slack - firefox (jitsi or google meet) - chrome (jitsi or google meet), - a dockerized zoom (https://github.com/mdouchement/docker-zoom-us/blob/master/scripts/zoom-us-wrapper) now there is the "more aggressive switching behaviour" : when specifying load-module module-bluetooth-policy auto_switch=2 Using auto_switch=2, almost works \o/ Using chrome : - Google meet session: autoswitch does lots of back and forth making my headset beep dozens of time (which is quite annoying). Sometimes ends up working sometimes not and I get loads of bluetooth/sound related errors in journald janv. 18 11:48:16 x1byjean kernel: Bluetooth: hci0: SCO packet for unknown connection handle 0 janv. 18 11:48:16 x1byjean kernel: Bluetooth: hci0: SCO packet for unknown connection handle 0 janv. 18 11:48:16 x1byjean kernel: Bluetooth: hci0: SCO packet for unknown connection handle 0 janv. 18 11:48:16 x1byjean kernel: Bluetooth: hci0: SCO packet for unknown connection handle 0 janv. 18 11:48:16 x1byjean kernel: Bluetooth: hci0: SCO packet for unknown connection handle 0 janv. 18 11:48:16 x1byjean rtkit-daemon[1817]: Supervising 7 threads of 1 processes of 1 users. janv. 18 11:48:16 x1byjean kernel: Bluetooth: hci0: SCO packet for unknown connection handle 294 janv. 18 11:48:16 x1byjean kernel: Bluetooth: hci0: SCO packet for unknown connection handle 294 janv. 18 11:48:16 x1byjean kernel: Bluetooth: hci0: SCO packet for unknown connection handle 294 janv. 18 11:48:16 x1byjean rtkit-daemon[1817]: Successfully made thread 773344 of process 770761 owned by '1000' RT at priority 5. janv. 18 11:48:16 x1byjean rtkit-daemon[1817]: Supervising 8 threads of 1 processes of 1 users. janv. 18 11:48:16 x1byjean gsd-media-keys[6497]: Unable to get default sink janv. 18 11:48:16 x1byjean gsd-media-keys[6497]: Unable to get default source janv. 18 11:48:16 x1byjean rtkit-daemon[1817]: Supervising 7 threads of 1 processes of 1 users. janv. 18 11:48:16 x1byjean rtkit-daemon[1817]: Successfully made thread 773349 of process 770761 owned by '1000' RT at priority 5. janv. 18 11:48:16 x1byjean rtkit-daemon[1817]: Supervising 8 threads of 1 processes of 1 users. janv. 18 11:48:16 x1byjean gsd-media-keys[6497]: Unable to get default sink janv. 18 11:48:16 x1byjean gsd-media-keys[6497]: Unable to get default source janv. 18 11:48:16 x1byjean kernel: Bluetooth: hci0: SCO packet for unknown connection handle 0 janv. 18 11:48:16 x1byjean kernel: Bluetooth: hci0: SCO packet for unknown connection handle 0 janv. 18 11:48:16 x1byjean kernel: Bluetooth: hci0: SCO packet for unknown connection handle 0 janv. 18 11:48:16 x1byjean kernel: Bluetooth: hci0: SCO packet for unknown connection handle 0 janv. 18 11:48:16 x1byjean kernel: Bluetooth: hci0: SCO packet for unknown connection handle 0 janv. 18 11:48:17 x1byjean rtkit-daemon[1817]: Supervising 7 threads of 1 processes of 1 users. janv. 18 11:48:17 x1byjean kernel: Bluetooth: hci0: SCO packet for unknown connection handle 295 janv. 18 11:48:17 x1byjean kernel: Bluetooth: hci0: SCO packet for unknown connection handle 295 janv. 18 11:48:17 x1byjean rtkit-daemon[1817]: Successfully made thread 773355 of process 770761 owned by '1000' RT at priority 5. janv. 18 11:48:17 x1byjean rtkit-daemon[1817]: Supervising 8 threads of 1 processes of 1 users. janv. 18 11:48:17 x1byjean gsd-media-keys[6497]: Unable to get default sink janv. 18 11:48:17 x1byjean gsd-media-keys[6497]: Unable to get default source janv. 18 11:48:17 x1byjean rtkit-daemon[1817]: Supervising 7 threads of 1 processes of 1 users. janv. 18 11:48:17 x1byjean rtkit-daemon[1817]: Warning: Reached burst limit for user '1000', denying request. janv. 18 11:48:17 x1byjean rtkit-daemon[1817]: Supervising 7 threads of 1 processes of 1 users. janv. 18 11:48:17 x1byjean rtkit-daemon[1817]: Warning: Reached burst limit for user '1000', denying request. janv. 18 11:48:17 x1byjean rtkit-daemon[1817]: Supervising 7 threads of 1 processes of 1 users. janv. 18 11:48:17 x1byjean rtkit-daemon[1817]: Warning: Reached burst limit for user '1000', denying request. janv. 18 11:48:17 x1byjean rtkit-daemon[1817]: Supervising 7 threads of 1 processes of 1 users. janv. 18 11:48:17 x1byjean kernel: Bluetooth: hci0: SCO packet for unknown connection handle 0 janv. 18 11:48:17 x1byjean kernel: Bluetooth: hci0: SCO packet for unknown connection handle 0 janv. 18 11:48:17 x1byjean kernel: Bluetooth: hci0: SCO packet for unknown connection handle 0 janv. 18 11:48:17 x1byjean rtkit-daemon[1817]: Warning: Reached burst limit for user '1000', denying request. janv. 18 11:48:17 x1byjean rtkit-daemon[1817]: Supervising 7 threads of 1 processes of 1 users. janv. 18 11:48:17 x1byjean rtkit-daemon[1817]: Warning: Reached burst limit for user '1000', denying request. -

Among my tests I ended up having to restat spotify and (chrome or firefox) a couple time because they could no longer access the sound devices. I always left spotify open in the background paused and after a test call I tried to resume the spotify playback and while the time was advancing, I didn't have any output on the headset. About the sonding like a robot part : >From what I read so far the HSP/HPF profile currently uses the CVSD codec >which in turn uses an 8-bit sampling rate. This is a pretty extreme compromise between bandwidth and sound quality (in favor of bandwidth). IIUC this is what makes me "sound like a robot". When using the same visio apps (slack, google meet, jitsi meet, etc) with the laptop's built in microphone people report a much much better sound quality, unfortunately that also picks up keystrokes and mouse clics which is failry annoying/distracting for my interlocutors when I do presentations (product demonstration or live coding). I wonder if it would be possible to use a different codec/sampling rate (through configuration) or ideally an app driven sampling rate, this way the app could optimize the bandwidth/sound quality based on actual network conditions ...
