T420 Mic mute button and Volume Mute buttons problem and 1 Q

Ok so i’m hopeful this goes here - Ok so i got a Lenovo t420 second hand used last month and waited until Leap 42.1 was released and now installed and everything going good but i got 2 Very minor problems but nothing that can’t be patched / fixed - 1. the mic button doesn’t un mute the mic after being pressed once and pressing again does nothing and 2. the same is for the volume button

which they both work in Windows and Other Linux systems like Archbang and Ubuntu

and a Question i got is i wanted to put

i915.i915_enable_rc6=1 i915.i915_enable_fbc=1 i915.lvds_downclock=1 i915.semaphores=1

in kernel so i went to Yast -> Boot loader -> Optional Kernel Command Line Parameter and put the code there and now i currently wonder - will take effect every reboot/start up/resume ??

also sorry if i mistyped anything now a days i tend to go blind in 1 eye …that is until next month :open_mouth:
