#512: module-jack-sink segfault
----------------------------+-----------------------------------------------
Reporter: matth45 | Owner: lennart
Type: defect | Status: new
Priority: high | Milestone:
Component: module-jack-* | Severity: major
Resolution: | Keywords: segfault jackd disconnect zombified
----------------------------+-----------------------------------------------
Changes (by matth45):
* keywords: segfault => segfault jackd disconnect zombified
* severity: normal => major
Comment:
Using the attached simplified default.pa configuration file pulseaudio no
longer causes a segmentation fault, but it loses its connection to jackd
(looking at the debug output above the lost connection seems to be the
root cause of the error).
Here is the output for the new default.pa
