I am having trouble getting the volume scroll on my keyboard to exhibit the behavior I would like. My keyboard is a Redragon Horus K619. It works as one would expect in Windows with a generic Microsoft driver, a smooth but fast and responsive volume scroll from 0% to 100%.
In KDE, it seems like the volume scroll wheel is treated like a volume key, so with the default key repeat delay of 600 ms and rate of 25 repeats/s, the volume scroll behavior is erratic. Sometimes it does not start scrolling, scroll speed changes, and it scrolls up faster than down.
I changed the delay to 300 ms and the rate to 50 repeats/s as a middle ground to also work with typing, but I don’t like this behavior for the rest of the keyboard. I tried some other models listed as multimedia and did not have any success. Is there a more suitable model than the Generic 104-key PC model? Or is there a way to change the delay and rate for specific keys instead of across the entire keyboard?
