View Full Version : MBOX pops and clicks on a Win/PC system
08-09-2005, 02:52 PM
I just installed a friends Mbox (PT6.9) on his P4 XP Pro SP2 brand new PC (2Gb ram), and every minute or so during playback I hear an awful crackle, pop and click noise.
It sounds like a clocking issue, but I have the Mbox clocked internally.
We are working from the OS hard drive, as he can't afford and external drive right now. Could that be the problem?
I'm a Mac guy, so my Win troubleshooting is a little rusty.
i've never used an mbox, but it's audio interface with the PC is via USB, right? if that's the case, one thing to definately check is if there's an IRQ conflict. this might happen if windows has assigned the same IRQ number to 2 devices (in this case it would be the USB ports assigned to the same IRQ as something else). with xp it can be a serious pain to reconfigure this, i won't even go into it, you'd just need to do some searching with google to figure it out, but it may mean having to go into bios and altering some settings there to free up and/or change around the irq settings. the other thing to check is your mbox drivers latency setting. try cranking the buffer size up and see if that doesn't help.

I know nothing about the Mbox either...but make sure you are connecting it to one of the computers USB ports and not a HUB.

The Mbox is connected to the computer directly.
Since he only has 2 USB ports, I connected the keyboard and MIDI controller keyboard to the hub.

I spoke with a rep at Digidesign and here's the tips he emailed me. Sorry about the length, but this should help anyone who is having difficulty installing a Mbox on a new PC.
Update your Mbox firmware...
Here's where to find it and how to run it:
System hard drive > Program Files folder > Digidesign folder > Pro Tools folder > Pro Tools Utilities folder > Firmware update. Double-click on the firmware updater and follow the prompts.

To create a Hardware Profile:
By creating a Hardware Profile for Pro Tools you can disable devices in the Device Manager that could be conflicting with Pro Tools. When you disable devices in the Pro Tools Hardware Profile, the Original Configuration remains untouched; thus, all devices will still be enabled in the Original Configuration.
* Start menu > Control Panel > System > Hardware Tab > Hardware Profiles > Copy > Name it: "Pro Tools" > OK > Restart. When computer reboots you can choose between "Original Configuration" or "Pro Tools", select "Pro Tools".
To disable devices in the Device Manager:
* Start menu > Control Panel > System > Hardware Tab > Device Manager > (ie.Open "Network Adapters") double-click on a device there > General Tab > Device Usage: Do not use this device (disable) > OK. Or, right-click on the device in the Device Manager and choose "disable".
