Created attachment 14722 [details]
screenshot of the split channel behaviour

Created attachment 14723 [details]
the corresponding kmix_panelapplet_rc

I can reproduce the problem. As it is looking very weird, priority is raised to VHI.
Target milestone: KDE3.5.2

I added a fix for this situation. I cannot reproduce this anymore with the fix.

The fixed version will ship with KDE3.5.2 . In the KDE4 branch this feature is not yet implemented - the issue must be kept in mind for KDE4.

SVN commit 512112 by esken:

Fix the "icons ruin vertical panel applet usability" issue.
Fix the "Split channel in kmix applet shows one channel as a slider, the
other numerical" issue.

BUGS: 122114
BUGS: 97666
