h/w buffer HELP

[tystick420]

Im doing a project in school tomorrow!using my avid mbox and PT9. All of the sudden its saying my h/w buffer size is not supported and i need to change it. (which has never happend it always works as soon as i plug it in.) So i go to Playback Engine to change it, and the drop down box isnt even their! im lost! My current h/w size is 44.1kHz default i guess. Help me ASAP!

What is it saying exactly----are you sure it's not that the audio is playing, it stops, and says you need to change the buffer settings?

"44.1kHz" is a sample rate and not a hardware buffer setting. Go to "Setup" - "Playback Engine" and you should have a drop down selection for "HW Buffer." The choices should be 32, 64, 128. 256. 512, and 1024 samples. Normally you select a larger H/W Buffer to give your system adequate time to process the audio data. The preferred setting is to use the lowest setting without problems for tracking (limited by hardware) and the highest setting when mixing.

You should also make sure that you have done all the other system tweaks to make your system perform optimally for Protools (not the same as optimally for a personal computer). These include turning off Wi-fi, bluetooth, anti-virus software and recording to a physically separate hard drive (not your OS drive)

I fell asleep late last night giving up cuz it wouldn't work, accidentally left my mbox plugged in.oops! woke up at 7 and it was working didnt do a damn thing. idfk. But the thing was that when i go to Playback Engine to change the sample rate the drop down box wasnt even their. now it is. i messed with it for hrs last night and went to sleep with it not working... PT likes to give me a hard time From time to time

Good to hear it fixed itself. It might be a good time to make a drive image of your working system so you can always come back to it when needed.
