We love to praise linux constantly and tell everyone to change to it (they should) but what are your biggest annoyances ?
Mine would be, installing software (made even more complex by flatpaks being added, among the 5 other ways there already were to install software) and probably wifi power management issues.
The audio stack is just just a nightmare, it’s not even funny. Sometimes, at random, when my PC boots, it will output white noise at full volume through my headphones. The is fine if I turned it on and went to get something, make a coffee, whatever. I can still hear it in the other room though. If I’m sitting at my PC and I was just rebooting, wearing the headphones: that isn’t ok. It damn near blows my eardrums out when it happens.
