Problems with Garageband and Presonus FireStudio Mobile
I just got the Firestudio Mobile yesterday after returning the M-Audio 610, which likewise didn't have these problems, but had lots of drop-outs in the signal.
Out of the box, installed the software, did the "update firmware" from Universal Control and rebooted. Hooked up the box, got the blue light, opened Garageband and started playing a project. No problem - until I went to choose another track and the sound muted. Checking the preferences in Garageband, "Presonus Firestudio" didn't appear as a driver choice - it had been booted. I did a full uninstall of the software, reinstalled and pulled the update from the Presonus website (latest version, right?), did the "update firmware" from Universal Control and rebooted. Still, after switching to another track in Garageband, the sound suddenly cuts out, though the meters are still showing that signal is flowing.
Universal Control hasn't been much help, since it has continued to behave oddly - first getting more noticeably sluggish until finally refusing to respond at all and locking up. I got lights at first through Universal Control, and then the meters fail to show anything. Each time between FireStudio drivers, I've dumped the family driver files, rebooted, repaired permissions, cleared PRAM and started fresh, paying close attention to how I updated the latest versions. Stranger still - when I turn the main volume down - I still get signal coming from the right monitor. Mono sound comes out of both speakers when I turn the main volume up. At least until I switch tracks to edit and then, the sound winks out and Garageband ignores the presence of the FireStudio.
This same thing would sort of happen with the FireBox (which I got rid of because channel 2 developed some kind of hum and loss of volume), but instead of completely muting volume, it would glitch and garble the audio signal until I stopped the track, gone into Audio/MIDI, switched the format from 48 and back to 44.1 to wake it up and continue on. The FireBox problem was occasional. The mute problem and kick out with FireStudio happens every single time.

Of course, thank you for any help.
