    UPDATE: Attached video - Playback Error - Exception: AFIFO_TAKE_UNDERRUN, CtrlBiFifo: Auto LFE 12

    UPDATE: I'm attaching a video to this post displaying our problem. See below for original explanation.

    Hello,

    We've just recently upgraded to Avid 8.6.1, and one of our editors is having a continuous problem with one of his timelines.

    There's several sections, usually ones with audio dissolves, that stop playback and give the following error code. This is the most recent one we've received:

    Exception: AFIFO_TAKE_UNDERRUN, CtrlBiFifo:Auto LFE 12

    I have a screenshot of the error code received yesteday on one and a screenshot of the full timeline to show that it's occurring mainly over audio dissolves.

    We were able to fix the problem temporarily yesterday by rebooting his whole system. But today, that didn't work. Another support forum post suggested rendering all audio. However, when we tried to do that, it said there were no effects to render despite that not being the case.

    Any suggestions or solutions?

    Haven't seen your system specs, but if you have an I/O box attached, try disabling it.

    Also, what version of OS X are you using?

    What sort of additional system specs do you need? First time forum poster, not sure what to include.

    We're running on OS X version 10.9.5. And we do not have an I/O box attached to the computer in question.

    @Avid AE MW: like Mondo said in that other thread, 10.9.5 is also a contributing factor.

    Ask IT if they'll clone your boot drive to another, then upgrade to Yosemite (10.10.5). Don't do El Capitán (10.11.x). If it continues under 10.10.5, you can always roll back to 10.9.5.

    Report back.

    @Isaquit0: I'll look into that.

     

    But we weren't experiencing this issue with 8.5 combined with 10.9.5 before... seems odd that it's happening now with 8.6.1.

    UPDATE:

    Something we learned today - just to provide as much info as possible - this error only occurs when a clip is using keyframes and a dissolve at the same time. If the clip has keyframes, it works. If the clip has dissolves, it works. But if it has both, doesn't work.

    Also, this problem is localized to one computer. Tested the same sequence on several other computers all running OSX 10.9.5 and did not run into the same problem. One additional computer was having issues yesterday, but I reinstalled some Avid files from the initial installation, and now it works fine.

    Have you tried doing the same to the affected computer?

    Yes, we re-installed files on the affected computer. Seemed to work momentarily, but then it happened more on other edit points - including the original problem point.

    Currently, the problem appears to be fixed. I honestly don't know how... we duplicated some sequences and then our IT manager did some work on the computer. I was out of the office, so I don't know exactly what that work was, but if I get a chance to ask him I will. He may have just reinstalled the program and its files.


    When talking with support, they asked if we had upgraded to 8.6 but the timeline was made in 8.5. This was indeed the case. Haven't heard back yet if they think that was the cause of the error - just putting it out there as extra info.

     

    So I guess I would call this solved? Although not really, because we don't know HOW exactly it was fixed. It just hasn't happened yet today.

     

    Thank you everyone for your help!

    quick quess is that you might have had a corrupt precompute/render. Moving to a new machine did you re-render effects. Could explain why it suddenly is working again. When effects are the issue it is always good to try removing the rendered data and re-render.
