Example of the tinkering still *needed* on PC:
I have a wireless headset, and not some niche set but Logitech G933s. If I want to use them to chat with my friends while playing my MMO (Final Fantasy XIV) while listening to game audio, I cant just turn the headphones on and go, I have to right-click the volume control in Windows, choose Playback Devices, select the G933 head phones, and click the Default Device button. I must do this every time. If I forget about it and start the game up, I cannot then enable the G933s, that will not give me game audio - the game locks in the audio that is enabled when it starts, so I must then exit the game, and *then* set the headset as the default device, then restart the game. Then when I want to go back to normal speakers, I have to do it again - turning off the headset doesnt do anything, I have to go back to Playback Devices and select my speakers (in my case, my TV set), setting them as Default Playback Device.
They also arent set as the default recording device for my gaming-related chat program, Discord, either - whenever I need to reinstall Discord, I have to go into the programs settings and tell it which device to use as the microphone and speakers.
This is just a small thing for PC users, but its one of the things casual gamers arent going to want to have to think about, and its not intuitive at all and WILL require research. Game consoles dont have this issue, headsets and speakers just work (except maybe the Switch when using headsets).
