Please double check pulseaudio isn't running via pgrep -af pulseaudio.

>From https://www.kde.org/applications/multimedia/kmix/ it seems kmix directly
uses ALSA, xfce4-mixer uses ALSA via gstreamer. So if two independent mixer
implementations on top of ALSA exhibit this problem then it might be a problem
either in ALSA or the underlying driver, open a new bug against ALSA with the
above comment and attach the output generated by /usr/sbin/alsa-info.sh
