Ever since upgrading my iPhone 5s to iOS 8, DM1s audio no longer works. Not only that, but apps launched after DM1 also will no longer have working audio (tried other drum machines, several metronomes, and some games). Going into the Sounds list and playing a soundfile seems to restore sound to the other apps, as long as I dont re-launch DM1. Hopefully it wont take long for this to be fixed.
