Thanks for testing and reporting this bug. It would be helpful to see the debug logging at least. Running with /usr/bin/pulseaudio ... --log-level=debug with that flapping test for instance.
Getting a symbolic backtrace would also be useful if you're able to: https://wiki.ubuntu.com/DebuggingProgramCrash ** Changed in: pulseaudio (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/2121311 Title: pulseaudio aborts in pa_bluetooth_transport_set_state() (Bluetooth/BlueZ integration) Status in pulseaudio package in Ubuntu: Incomplete Bug description: What happened - While stress-testing Bluetooth with a custom RFCOMM/L2CAP fuzzing harness on a separate Ubuntu test device, pulseaudio aborted in pa_bluetooth_transport_set_state() (module-bluez5 / libbluez5-util.so). The harness drives rapid, occasionally malformed transport/profile transitions—frequent connect/disconnect and state flapping. Steps to reproduce (high-level) 1. Pair/connect a Bluetooth audio device (e.g., headset/speaker). 2. Generate rapid transport/profile state changes (connect/disconnect/suspend/resume, A2DP ↔ HFP/HSP switching) using a test harness. 3. After a short burst (minutes), pulseaudio exits with SIGABRT in pa_bluetooth_transport_set_state(). Repro notes (from fuzzing) - Traffic rate: ~55 packets/second (mix of RFCOMM frames and L2CAP signaling). - Pattern: quick successive control/state transitions - Impact: user-session PulseAudio terminates Environment - Distro/arch: Ubuntu 22.04 (amd64) - Package: pulseaudio 1:15.99.1+dfsg1-1ubuntu2.2 - Cmdline: /usr/bin/pulseaudio --daemonize=no --log-target=journal - Device under test: separate machine used for Bluetooth fuzz testing Attachments - Apport crash: _usr_bin_pulseaudio.1000.crash (uploaded). Note: I don’t have btmon/journal extracts or pactl snapshots handy for this run; I can capture them on the test device if helpful.
