Bug ID: 313988
Summary: kmix crash when transfer audio stream with pulseaudio
Classification: Unclassified
Product: kmix
Version: 4.3
Platform: openSUSE RPMs
OS: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: general
Assignee: esken@kde.org
Reporter: benderamp@gmail.com
Application: kmix (4.3)
KDE Platform Version: 4.10.60 "release 1"
Qt Version: 4.8.4
Operating System: Linux 3.7.2-1-desktop x86_64
Distribution: "openSUSE 12.2 (x86_64)"
-- Information about the crash:
- What I was doing when the application crashed:
I have 2 sound devices (hda and hdmi audio), pulseaudio enabled. Open vlc (or
some other sound app) and start playing sound, click on kmix, right click on
vlc slider, select move item and transfer stream to another dives. Kmix will
crash on the 2nd time this was done most of the time.
The crash can be reproduced every time.
