While on wireplumber-0.5.10-1.fc42, this problem do not exist. After upgrading to wireplumber-0.5.11-1.fc42, problem starts to appear. Callstack in disconnected.txt: stack traceback: [string "device-info-cache.lua"]:36: in function 'device-info-cache.get_device_info' [string "state-routes.lua"]:185: in function <[string "state-routes.lua"]:179> [C]: in ? [C]: in method 'advance' [string "state-routes.lua"]:172: in function <[string "state-routes.lua"]:167> When the laptop boots, there is playback and microphone seems to be working. After connecting to the bluetooth speaker, there's still playback. However, the microphone from the bluetooth speaker no longer works although it shows up in GNOME Sound setting. Manually changing the microphone to the laptop's microphone didn't work either. Upon disconnecting the bluetooth speaker, there is no playback and no microphone, even when GNOME Sound setting properly show the laptop internal speaker and microphone. Reconnecting the bluetooth speaker shows the volume slider at 100%, without the ability to playback and microphone. Workaround: systemctl --user restart wireplumber.service Note that restarting wireplumber service while bluetooth is connected will playback garbled sound. GNOME Sound will only shows a center speaker in this case. Reproducible: Always Steps to Reproduce: 1. Connect bluetooth speaker 2. Disconnect bluetooth speaker Actual Results: No playback. No microphone. Software like Firefox will hang when it tries to playback. Expected Results: Playback and microphone works.

Created attachment 2106111 [details] wireplumber.service when reconnected to bluetooth after disconnect. Volume slider is pegged at 100% in this case. Note that I did try SBC-XQ during reconnect, and get "Invalid method call" during org.bluez.GattManager1.RegisterApplication() Manually reconnecting it the second time will get connected. But still no playback and microphone.

I get probably related issues, with Bluetooth disabled and USB headphones connected. The symptoms appeared every time I resumed from suspend. What I saw was: - YouTube videos hung in Firefox - The KDE Plasma volume control / audio device selection widget behaved weirdly (for example, trying to change the default output device using the radio button would end up with both radio buttons highlighted, but no working audio) - Whenever this happened, it was resolved by running: systemctl --user restart wireplumber pipewire pipewire-pulse I could 100% reliably reproduce this behaviour by sleeping and then waking the PC. This appeared after installing wireplumber-0.5.11-1.fc42 and disappeared after downgrading to wireplumber-0.5.10-1.fc42. When the issue happened, the journal entries during the suspend process showed a very similar Lua stack trace to the one that the bug reporter got: Sep 13 20:29:35 wireplumber[2497]: wplua: [string "device-info-cache.lua"]:36: attempt to call a nil value (field 'critical') stack traceback: [string "device-info-cache.lua"]:36: in function 'device-info-cache.get_device_info' [string "state-routes.lua"]:185: in function <[string "state-routes.lua"]:179> [C]: in ? [C]: in method 'advance' [string "state-routes.lua"]:172: in function <[string "state-routes.lua"]:167>
The cause seems likely to be this upstream bug: https://gitlab.freedesktop.org/pipewire/wireplumber/-/issues/854 A fix is planned for 0.5.12.
