Title:
Pulsaudio crashes once BT microphone is connected
Status in pulseaudio package in Ubuntu:
Fix Committed
Status in pulseaudio source package in Jammy:
Fix Released
Bug description:
* Impact
When I connect my BT headset with microphone and change profile to HFP,
Pulsaudio crashes, sometimes even crashing Gnome itself.
* Test case
- Connect a bluetooth headset to the computer
- Try to change the profile to HFP from the desktop settings or the
pulseaudio cli
-> the profile should get correctly selected, the service shouldn't
crash
* Regression potential
The changes are in the functions handling mSBC packets which handle
bluetooth HFP codecs, so any regression would concern bluetooth
devices using that profile.
