This is for any users of "Classic" KMix - that is, the standalone program that works with ALSA and OSS as well as PulseAudio, not the Plasma 'plasma-pa' panel applet.
Along with the main executable it also installs and automatically starts a KDED module 'kmixd' which appears in systemsettings as "KMix Daemon". However, it's not clear exactly what is the purpose of this KDED module. It seems to do exactly the same as KMix does itself, watching for hotplugged sound hardware and updating the internal data structures and saved configuration, but without a GUI. It does expose the available mixers and controls via DBus, but that access is available via the same interface on the KMix application itself. I suspect that this was intended for use by other volume control applications such as KMilo which managed laptop hotkeys back in the KDE3 days, but I don't know of any applications that use it now. The Plasma applet does not use KMix or any of its interfaces - indeed, if plasma-pa is installed it installs an update file which disables KMix autostart. Therefore I'd like to remove the KDED module from KMix. For the moment there is some code (commit 6ede7122 in master branch) that unloads the module and disables its autostart via DBus when the KMix application starts up. If this does not cause any problems with KMix itself or any third party applications then later on the module can be removed completely. I have been running KMix with the module disabled for a long time and have not observed any problems. But, for the moment, please report if the module being disabled causes any problems for you or with any other applications. If needed it can be reenabled on the "Background Services" page in System Settings until KMix is next restarted.
