'I HATE DRANS!' Sometimes it goes quiet for the rest of a cutscene, usually soon after ringing. In cutscenes (and so far, only cutscenes), really weird things happen. So I 100/120%'d Spyro 1 this morning and moved onto Spyro 2.
The only way I've got it working is to reset the game, which is annoying. I tried pausing/unpausing, changing audio settings (already had SFX 3 bars, music full) and exiting the level and re-entering it.
The music kinda plays when a dragon is talking. The sound effects work fine, but there's 'machine gun' noise in the background. On Spyro 1, sometimes the music doesn't play. I don't know if it's a scratched disk or the system or what. Since I no longer have a working PS1 nor any PS1 memory cards, I played them on my PS3. I started playing my PS1 Spyro games again maybe two weeks ago.
