#Mac audio input not working el capitan pro

With Pro Tools not running can you use the interface as an input and output for other apps in OS X? Like Garage Band? Has this ever worked for you? If so what changed? Does the interface work in another computer? (yes it's unlikely to be a hardware problem, but if it's easy to exclude that then great). I know M-Audio claim compatibility with El Capitan and Sierra, but it may help if others who have/are having simmilar problems see what you are on. Your profile says El Capitan is that info up to date? (stuff thre is frequently not, so it helps to say in your post). What exact OS X version? (what disk drive type you have is not interesting, what OS you are running may be). You are running Pro Tools standard or Pro Tools First?

Number and type (firewire, SATA, SCSI, etc) of drives installed, how they're formatted and which one(s) you're using for recording and playback.

We need to know to which port on the computer they're connected to, what type of cables you're using (is it a FW800-FW400 adapter cable? How long is it? Are you using an extender or repeater?) and, if you've tried replacing cables, what the differences were between the original and the replacement.

A complete and precise description of any attached peripherals (hard drives, video devices, other FireWire or USB devices that may be attached, etc).

'At the very least, we need the following information: Including all of this would be helpful (from the Avid Site):
