Angry Re: No Output with New System

Now go back to sync source in upper right corner and change back to internal-digtal unmuted.

Caution: Turn your speakers down before doing this or you will have a subwoofer jumping off the floor like I just did. LOL

You will need to do this every time you restart your system until a new driver is released.

Hello, I realize this post is a few years old, hopefully you're still on the forum. I searched this issue and thought I'd try to contact you as it was the nearest subject in search. I have a Macbook 10.6.8 ProTools M Powered with Firewire 1814, current drivers. The other day, out of the blue, suddenly I have no output audio. There is signal coming in as evidenced by the signal meter. Although no audio in headphones. It appears to record audio and playback as evidenced in the waveforms, but no audio. The only thing I can think of is that a few days earlier my computer acted weird, with the spinning wheel, browser working slow and weird. Rebooting computer seemed to take care of that but not for ProTools/M Audio. Any help appreciated
