Re: hid.c - need enable_5_button_array=1 for hardware volume buttons

[thysupremematrix@tuta.io]

Hi,

Is there any update regarding this? I understand we're all volunteers here, so I don't mind the wait — just want to know if it's getting processed. Also, another note that due to unforeseen circumstances I can't access my laptop for a few days until I reach the city.

Thanks,By Matrix :)

I found that after some digging, sudo modprobe intel_hid enable_5_button_array=1 seemed to work. The documentation at https://github.com/torvalds/linux/blob/master/drivers/platform/x86/intel/hid.c said to contact this email.

Maybe we need to apply the fix to every HP laptop that has volume controls? Thoughts?
