Audio doesn't work

[TheDax]

Don't take this the wrong way, but start with the very basics:
1. Make sure you actually have sound turned on in your OS/device.
2. Make sure you have speakers/headphones connected and turned on.
3. Once you know it's not your system, make sure PPSSPP's sound volume is cranked up to 8 on both, and that both checkboxes for Sound and Atrac3+ are both ON/enabled. It might help to restart the emulator after downloading the plugin as well(for some reason if you start a game without sound and then enable it via the menu, it never works).

Hope that helps. I'm not trying to insult your intelligence or anything. Just fall back to the basics if things go wrong, then tackle the more complex things.
