SUMMARY
I use archlinux (a rolling release linux distro),
since a recent update I notice at startup segmentation fault related to
kmixctrl (version 4.6) in dmesg :
[ 72.047675] kmixctrl[787]: segfault at 0 ip 0000000000000000 sp
00007ffd2a3ff0e8 error 14 in kmixctrl[5628352c9000+2000]
[ 72.047682] Code: Bad RIP value.
You can also trigger the bug by opening a console, then type "kmixctrl", you
will notice a segmentation fault message, if you use the last release version
of KDE plasma, kde frameworks application, and QT5 (5.15 version).
