Pro Tools 8 and Vista - H/W Buffer Problem!

Somebody please help! I've already moved sessions from drives, changed drives, and used different firewire ports. I know that I need to upgrade my ram but shit! It doesn't even play 3 tracks!

That really isn't enough RAM (in my opinion), especially if you're running Vista. A move to XP would improve your performance immensely.

Also, when I was having the buffer underrun whatever errors, Disabling my network card fixed all my problems. Doesn't mean it will for you, but it might help.

Sorry Josh, I probably posted in the wrong place. I'm running on OSX Leapord not Windows Vista. 1.5 Gb should be enough ram to play 3 tracks

[bugbrain_04]

I should have realized that when you said you were using a G5. And instinctively, I would think that 1.5 would be enough RAM for that in OS X (Though that's really more of just a halfway-educated guess than anything).

One thing I ran across is that PT8 is only officially compatible with OS X 10.5.5 or 10.5.6. Could that be causing problems?

You aren't using a kensington mouse perchance?

[tkennedy_jazz]

Not sure of the brand of mouse I'm using. I think its a regular old apple wireless mouse. Could this be a problem?

[petersrin]

Nope. Just kensington trackballs are causing problems like your description.

Thanks for those notes audiogeek, I have been recording to my C drive and get the ol' buffer error on my laptop but rarely ever happens on my desktop.
I usually don't have any issues when recording from my midi controller, all hell breaks lose when I plug in the guitar. So I just copy the project files on to a jump drive and finish up on my desktop, drums and bass take me forever and I like to sit back in the recliner to do that. lol

When im recording it randomly just stops playing and recording and says 'Pro Tools is unable to communicate with HUI. Power-cycle HUI and check its connections. Note, if HUI is not in use, update the Peripherals dialog to prevent further warnings'...
I dont no whats going on cos iv tryed loads of stuff... Im running pt 8 m-powered with the projectmix io. specs are below....thanks..

does anyone hav this prob or did they hav it... or even no anything about that can help??

[Audio~Geek]

a few things I can think of.

1- only one drive in your PC? You need 2 for pro tools
2 - Drive speed should be 7200rpm
3- Firewire card should be using a Texas Instruments chip.


HUI is the protocol for the control surface functions of your interface.

In peripherals it should be set to Motormix, 1-8 input, 1-8 output.

If it's losing connection it could be caused by IRQ sharing.
