I have never used this particular Mbox so part of the problem is that I'm not sure if the mbox is just straight up broken. When I have a Protools session and I try to play back my audio files, I only hear a regular clicking noise in the headphones that I can turn up and down with the volume knob. I checked the outputs and made sure that the master fader was outputting on the correct channel and it still gives me no audio in my headphones. Quite confused, please help.
After re reading the problem, what version of pro tools are you running? If your running a newer version then 6.9 you might need to upgrade the firm ware in the mbox as well. Go to Digidesign.com and go to downloads Mbox firmware. What version of protools are you running?
Double check and Ensure your headphones work.
Ensure that the master level is turned all the way to the right (Playback). I would also check that the main audio out of the Mbox is functioning so use two TRS 1/4" [balanced] cables to and amp and speakers to ensure master output jacks give you the same result. If they do chances are the Mbox is bad, if not it could be just the headphone preamp is bad

After installing soundflower, it should show up like a virtual soundcard in your sound prefs. Send your audio output to the soundflower 'card' in sound prefs. Then use LineIn to route the outpout from soundflower to the Mbox like this:
This means that your firmware on the Mbox and the drivers need to be updated. I had the same problem afte updating my protools from version 6.7, Did you recently do any protools upgrades? You can go to Digidesign>My Digi>downloads>Mbox>firmware updates or>driver updates
i'm running os 10.5.6 w/ protools 8.0 and the original mbox. i had the same problem. protools opened and seemed to work except there was no sound from either analog outputs or headphones. this worked for me: 1. shut down computer 2. unplugged all usb cables except keyboard/mouse 3. restarted computer 4. re-plugged usb cable from computer to mbox 5. opened protools session 6. hit play and now i'm hearing sound and everything seems normal.
it doesnt sound like its the mbox more maybe the protools install. But as far as the cable goes can you tell me if you can ping the mbox throught the 1394 connection. If you cant ping it then damage may have been caused to the unit and it may need to be serviced. I fix my own M-box's but in my store it only costs around $50usd to fix almost all problems with a mbox2
sounds to me you have a common problem of the mbox 2 blowing the maximizer. i had this happen on one and fixed it myself by purchasing new capacitors and replacing the ones on the pcb board.you can actually change a few capacitors to make it alot better. such as a mbox one with the better capacitors
