I did a search for this and didn't come up with anything helpful.

We are working on upgrading our old HP workstation to new quad core systems. MC 3.5 with Mojo worked perfectly on the old systems.

On the new system, when I play a timeline, the audio will pop and click. If the audio waveform is showing it's pretty much impossible to work, without it, the pops and clicks are less, but it's its still quite annoying. There are pops and clicks when using media from the Unity and on a local drive. When not playing through the Mojo, everything works as it is supposed to.

There is no Firewire on the motherboard, and the system has a PCI FireWire card. I tried moving the FireWire to the other PCI slot, and I tried with an additional 3 FireWire cards, which only made it much worse. Removing the Fiber card does not help.

We ordered 2 of these new workstations, and they both have this problem. Is this system simply not able to play nicely with the Mojo, or is there something I'm missing?

Thanks in advance!

Audio project settings?  Maybe sample rate set to something other than 48kHz?

I have had a similiar problem when playing timelines with mixed sample rates clips. hth

Thanks for the replies

Audio project is 48Khz and all media is 48khz

You don´t have any description of what audio card you are using ( propably onboard as you have probs ) in your profile, tell a little more about your system in your profile and you might get more answers

Audio card is onboard. The problems I am having with audio are when I am using the Mojo. Playing back through the onboard audio works fine.

Thanks

Sometimes these problems are due to the USB controller chip. Check to see if the USB port is one controlled by the South bridge Intel chip or a secondary chip on the MoBo. Also anything else that is using the USB controller could be taxing the bandwidth.

Sometimes onboard sound is ok, but many are using an audio card to ease the load on the CPU. Audio cards enabled for ASIO2 work best.

All USB controllers are Intel ICH10.

Again, onboard audio has no problems, only playback through the MOJO is problematic.

When I playback through the Mojo, I get stacks of error messages like this in the console -

It might be a bad Mojo itself.  There are defective ones out there.

Your MoJo is Firewire? Is the firewire card sharing resources with something else?

Tried another Mojo, same thing

Firewire is sharing IRQ 17 with ethernet and and USB controller. Disabling everything else on the IRQ doesn't help.
