New information for this bug. The problem is in ~/.kde/share/config/kmixrc file. Part of strings in this file contains names of audio devices transtated into russian (e.g. "Устройства_воспроизведения_звука" instead of "Playback_Devices") and "?" symbols in device sections. I have replaced this names with English and all is ok. But kmix rewrites config file during launch and all errors comes back. Now I have set 444 rights on this file and kmix works fine, but shows warning about insufficient rihgts on startup. So, we need to remove some extra lines from kmix translation.
