If Slacker has been running and the telephone receives a call, the Storm ringtone works. However, subsequent calls will only have the Storm vibrate (no ringtone). E-mail and text msg tones will still work.
A battery pull is needed to restore the ring tone.
This has happened to me and what I found works is if I put my sound profile on silent while listening to slacker then all alerts/ringtones are still in tact after listening.
