Cannot play sound from iMac Late-2013 through HD Native Thunderbolt I/O 8x8x8 System

[annaslwong]

Hi, all experts,

I have purchased the Pro Tools HD 11 with HD Native Thunderbolt + HD Omni System. It is connected to my iMac Late-2013 in OS10.9.5 with 1TB Serial ATA SSD. I can play sound at Pro Tools but cannot play any sound from Quicktime, iTunes, Final Cut Pro and other softwares. Once I played sound from those mentioned softwares at iMac, a warning notice pops up, saying "Avid CoreAudio Manager quit unexpectedly" and "XXX(the software for playing sound) quite unexpectedly while using the Avid CoreAudio plug-in." Maybe I have made some mistakes at the setup...Can anyone help? Thousands thanks.

Best regards,
Anna

Hi there,

same problem here with a HD Omni.
Once in a while the Core Audio accept to play iMac sounds, but it is not working anymore if you boot ProTools. Plus it crashes often.

They did a real bad job on the HD drivers I think. I'm using a HD Omni for a few weeks now, and I miss my MBox Pro drivers, so much easier and usable on a daily basis...

I finally plugged a cable in the iMac out into Line in onto the HD Omni, so I could get rid of this problem...

But if someone has a solution, i mean a real one, that would be awesome

You cannot get system sounds/iTunes audio and PT audio while PT is open - that is a known issue. You have to go with a separate output from the Mac to whatever monitoring system you're using.

Dear Jack,

Thanks for your reply! I know that too. But the problem is, even I close PT, it still can't play the system sounds and iTunes audio...

You can't just close PT but have to quit it. What do you have your system sounds and such set to output to?
