Yes, your OS needs to support your hardware. That's to be expected.Spoken like a person who never used a GP2X. When you make the volume control through software, people have to support it for it to work. That's why plenty of games for the GP2X forced you to go into menus to change the volume, or worse: didn't even allow you to change the volume in game. You had to literally exit the game, change the volume, and then start the game again for those. This exact problem can arise on the Pyra if people try to use other images like they did on the Pandora. (Android, Arch, etc.) Because they will have to support the volume wheel rather than it just working.
