Not sure if this is the right category, so please tell me if wrong.
After reinstalling (from scratch) my laptop into Stretch (9.4), my keyboard volume controls stop working after resume from suspend. This is really annoying. How can I start investigating the cause?
I have of course googled, but as not found any relevant solutions that works. Please help me start digging
