It's just basic security. Direct access (ie no trusted intermediate software layer) to physical hardware is a minefield.
- wizzwizz4 6y agoWell, yeah, that's the reason for the convention – but it isn't quite that simple. Control of the PC speaker should really be available to all users in `audio` by default, because in most setups it has exactly the same attack surface; running software as `sudo` instead is worse from a basic security perspective. In this case, the driver is a trusted intermediary layer – at least, I think it is.
