I'm using Presto Sound Library with Astro Player (latest version of both).
First off, let me say it's *fantastic*. Thank you for doing this! You've literally saved me days of listening and I'm so much more efficient because of it.
That said, should it work with .ogg audio files? When I load an .ogg into Astro Player, it plays at 1x speed no matter the speed setting. Conversely, .mp3 files speed up just fine as expected. Maybe Astro Player isn't using Presto for .ogg playback and is instead using say the built-in player?
