    Exception: Legend Audio Communications error, Hardware Underrun

    I get a pop of white noise followed by the above error fairly often. Avid does not crash, I can save but the software requires a restart to function again. I have attached a console screen shot. Anyone else get this issue? I don't think we see this on other systems we have in house. This popped up in version 6 and have seen it in all versions since. This is running Symphony 6.5.0.1 on Mac 10.7.3

    Re: Exception: Legend Audio Communications error, Hardware Underrun

    I keep getting this as well in Symphony 6.0.3.2 playing footage off our ISIS 5000. Anyone have insight into what might be causing this? It's really frustrating!

     

    UPDATE **

    We've now started seeing this on two other of our machines. One is a Symphony Nitris DX setup identical to my own, and the other is a Media Composer Mojo DX.

    I haven't had this issue since upgrading to 6.5.2, maybe something has changed in the latest version.

    That's good to know! It's a glaring issue in 6.0.3.2!

    Re: Exception: Legend Audio Communications error, Hardware Underrun

    Powered up my system this morning, loaded the sequence and got the same error as soon as I hit play.

     

    Console log shows this:

    Re: Exception: Legend Audio Communications error, Hardware Underrun

    We upgraded our RAM last week from 4GB (the minimum for v. 6.x) to 14GB, and it's almost entirely fixed my problem! It was appears to have been an issue where the hardware wasn't able to keep up since there wasn't enough RAM.

    Re: Exception: Legend Audio Communications error, Hardware Underrun

    Can confirm that this is a hardware related error.

    I had this error with Avid Mediacomposer and Nitris DX connected on following hardware configuration:

          Model Name: Mac Pro
          Model Identifier: MacPro3,1
          Processor Name: Quad-Core Intel Xeon
          Processor Speed: 2,8 GHz
          Number of Processors: 2
          Total Number of Cores: 8
          L2 Cache (per Processor): 12 MB
          Memory: 4 GB
          Bus Speed: 1,6 GHz
          NVIDIA GeForce 8800 GT
          Osx 10.7.5 Avid MC 6.0.3.2

    We changed this to newer hardware:

          Model Name: Mac Pro
          Model Identifier: MacPro5,1
          Processor Name: Quad-Core Intel Xeon
          Processor Speed: 2,4 GHz
          Number of Processors: 2
          Total Number of Cores: 8
          L2 Cache (per Core): 256 KB
          L3 Cache (per Processor): 12 MB
          Memory: 6 GB
          ATI Radeon HD 5770

          Osx 10.7.5 Avid MC 6.0.3.2

    This solved our problem and resulted in much better responce during editing.
