http://bugzilla.opensuse.org/show_bug.cgi?id=1192181 Bug ID: 1192181 Summary: brightness keys mute mic instead (HP Elitebook 840 G6) Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: andreas_nordal_4@hotmail.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- On a HP Elitebook 840 G6 laptop, both the backlight brightness keys (F3 and F4) toggle microphone mute state instead of doing their intended thing. The good thing is that other keys, such as mute, volume and the actual microphone mute key (F5, F6, F7, F8) work as intended. No messages appear in dmesg --follow or journalctl --follow when pressing these keys. In evtest, the brightness up and down keys appear as the same identical sequence, which is also a common prefix of the actual mic mute key: Common prefix: type 4 (EV_MSC), code 4 (MSC_SCAN), value 81 type 1 (EV_KEY), code 190 (KEY_F20), value 1 -------------- SYN_REPORT ------------ type 4 (EV_MSC), code 4 (MSC_SCAN), value 81 type 1 (EV_KEY), code 190 (KEY_F20), value 0 -------------- SYN_REPORT ------------ Actual mic mute key (unique suffix part): type 4 (EV_MSC), code 4 (MSC_SCAN), value 42 -------------- SYN_REPORT ------------ Kernel: Linux 5.14.6-1-default I found similar reports about these keys not working: 1. https://bugzilla.opensuse.org/show_bug.cgi?id=1105997 2. https://bugzilla.opensuse.org/show_bug.cgi?id=1160911 The first one was about not showing it correctly, but the last one says: Update: The issue is gone in the latest BIOS update issued by HP.
