Can't playback demo
I recently purchased the Mbox 3 with Pro Tools LE 8.0.4. I'm not yet using an audio drive, but am instead using my system drive (specifically, the C drive on my PC).
Could that fact that I'm using the system drive be why I can't get through a full playback of the Filtered Dream Demo Session?
Here are the errors I encountered and what I did to troubleshoot while trying to play back the demo:
When I loaded the demo, I saw this message:
"The original disk allocation for this session cannot be used. Check the disk allocation window to see what's changed.
Your I/O setup has changed since the last time this session was saved. Check the I/0 setups window to see what's changed."
I figured that might just be because the demo originally existed on the installation cd rather than on my drive, so I continued.
The first error message was:
"The audio device buffer underflowed. If this occurs frequently, try decreasing the "H/W Buffer Size in the Playback Engine panel or remove other devices from the audio firewire bus. (-6085)"
In response, I changed the H/W Buffer size from the original 512 samples to 256. I was able to play the demo for almost a full minute, then got this error:
"You are running out of CPU power. Remove some RTAS plug-ins or increase the CPU Usage Limit in the Playback Engine dialog. (-9128)"
Back in the Playback Engine, I changed my CPU max percentage from 85% to 90%, which was the maximum allowed, but I still couldn't play the demo for more than a minute or so. I moved the H/W Buffer size down to 128 samples, and that didn't change anything.
One thing I noticed was that the CPU usage, as seen in Windows Task Manager, was usually around 20%, and only rarely got up to even 50% while the demo was running. So I have doubts about whether the problem is really CPU capacity.
Thanks to anyone who takes the time to read this. Below is the information asked for by the 'Help us to help you' post:
