Hello!

Looks like that those keys are not as obvious as you wrote. Look at my
email with some investigation about Dell Audio With Preset Switch key:
https://www.spinics.net/lists/platform-driver-x86/msg15593.html

Also there is another user who wrote about 0xe02c key generated by
Inspirion 7520: https://ubuntuforum-br.org/index.php?topic=105434.0

You can a testing machine 5420, can you prove that behavior described in
my previous email match also your machine?
