Bug 303608 - Kmix crashed after selecting Amarok as master and instantly crashed when changing song. Volumes in exeption of the integrated subwoofer go fine; the built-in woofer must be changed trough Alsa, and Amarok must be volumed up/down by it's bar.

Description Adrià 2012-07-16 09:32:32 UTC
Changing song; not selecting Amarok as master, doesn't makes crash. Kmix stays in a false ''mute'' state, wich remains like that even not muted in alsa, etc. Leave in it in default master, doesn't makes Amarok crash, but volumes basically doesn't have any way to be changed. Downgrading kmix to 4:4.8.2 instead of 4:4.8.4 makes a stable-not-selected-Amarok as master kmix, can change songs with no problems, and sometimes hungs, but not in every change it suposed to affect the kmix-amarok shared instructions. In the two versions, the channel ''subwoofer'' it has no effect; only in Alsamixer, the one called ''internal'' does it's paper. Kmix 4:4.8.4 becomes ''invisible'' but visible as muted, it is there, but as not because you can't change any volume. in the downgrade, kmix is stable, always you don't select ''Amarok'' as master, changing songs with success;

Reproducible: Always

Steps to Reproduce:
1.Start kmix and Aamarok
2.Select ''Amarok'' as master in kmix
3.Changing song will automaticaly crash kmix.
Actual Results:  
Don't selecting Amarok as master makes kmix stable.


Downgrading to kmix 4:4.8.2, and don't selecting Amarok as master, makes kmix stable.

Comment 3 Christian Esken 2012-08-23 07:03:45 UTC
The debuginfo packages for the KMix application are not present, as teh information is missing in the backtrace.
---
Please post a backtrace including KMix debuginfo and report it here.

Distribution specific installation guides for installing debuginfo packages can be found on http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports

Especially important is that you do not forget to install the debuginfo packages for the KMix application.

No reply within 6 months => closing ticket
Also very likely a dup AND fixed.
