pulseaudio hangs up when bluetooth headset disappears

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Using pulseaudio 3.0 on Fedora 19, I have been experiencing pulseaudio
hanging up to the point of needing to be killed with a SIGKILL when my
bluetooth headset disappears (i.e. out of range, or turned off, etc.).

When this happens, the following stack trace can be observed:

In particular the hung thread looks like:

Any ideas?
