MBox 2 Pro problems - no sound (Windows XP Pro)

[charliemizza]

My MBox 2 Pro has apparently stopped working......

1st of all - yes, i have checked my drivers, etc in Device Manager. It says the device is working properly....and YES, I of course checked my cable connections, etc etc. I DID see that the "SM Bus" driver had the yellow "!" next to it. I googled it and it said basicly that driver controls the managment of power (electric) and thus manages temperature of the motherboard (this is where I got a little nervous....). So I updated it. I don't think it did a damned thing. Probably a waste of time too. I didn't notice the conditions get any worse afterwards, mind you.
I use the MBox as my ONLY sound card on my computer, i.e., Reason, Windows Media Player, etc - all use this hardware, and quite well...until now. I first noticed the problem when i tried to play a .wav file, a rough pre-master i did a week or so ago. i loaded it up on WMP and the play bar was moving, the lame "tie die" graphics moved to the beat of the music and everything...just no sound. the first thing I did was check the connections. All good. So I thought if my MBox were malfunctioning then surely PT wouldn't run, right?...............Pro Tools ran just fine - the faders lit up, counters were counting - everything was great except NO SOUND. I tried pluging the Firewire cable in the 2nd port on the back of the MBox, still with no avail. I also know that unless your firewire port lacks power than it is not neccesary to plug a AC adapter to it. I tried it anyways....still nothing.

I REALLY HOPE SOMEBODY HAS AN ANSWER FOR ME - since it is IMPOSSIBLE to get someone on the phone......................:ma d:

You say it stopped working, so I assume you had it working befor ?

1) Have you checked that your Mbox is the Default playback device under :
Control Panel -> Sound and Audio Devices -> Audio ?
2) Have you tested with headphones ?
3) Have you installed Quicktime ?

4) Have you used the Tech Support Folder (for Pro Tools 8) to trash preferences, remove plugins, delete pt folders, etc ?

I actually think this may be a power issue......I have a 30" Samsung monitor for which I had to install a bigger power supply. I was reading on Intel's website about the SM Bus driver. This driver apparently regulates power distribution for the motherboard. My girlfriend was editing some photos on Photoshop for over 8 hrs, so maybe it just shut off the sound card to conserve power, and prevent overheating......

I don't know - like I said...weird
