    Major audio problems with MC 5

    I dont know if anyone else is experiencing these audio problems with mc5

    When restarting my computer and re-opening a project, all audio using the audio mixer returns all audio back to dead 0.

    This is a long project (over 2 hours) with over one hundred of audio tweaks and cuts, every one has returned to zero.

    There are also many other audio problems I am experienceing like, audio just stops playing, then returns. Audio gets louder and lower randomly.

    I haven't had my audio "zero" out on me, but I am experiencing the same random audio "dropouts" and level changes that you're experiencing as well. For me it's on a number of DV25 projects (SD, both 32kHz and 48kHz media) and it's been happening since day one of MC5 upgrade. It seems to be more prevalent on clips with multiple audio adjustments going on, such as Clip Gain, Auto Gain and around realtime audio dissolves. But it happens on simple tracks too... so maybe scratch that idea. Stopping playback and starting again right away "fixes" it, but this obviously negates the possibility of playing out to tape.

    Exported Same as Source QTs are all perfectly fine so I haven't tried to troubleshoot too much. I was hoping for it to be a known issue, since it's really quite obvious (and alarming) if it's happening.

    I thought it might have been my motherboard's Realtek HD Audio, but maybe not, since you've got the same problems with SoundMax. I will try the MC 5.0.1 update but there's no indication of this being fixed or being a known issue in the ReadMe. If I get adventurous I may try popping in an old Creative SoundBlaster PCI card at some point.

    Another thought may be that my projects were started under MC v4, so I have not yet tried with media captured in a newly created MC v5 project. I can't imagine this being a problem though...? (Famous last words.)

    My system is not "authorized," so I understand the difficulty of finding a solution. Can anyone else shed light on this?

    Re: Major audio problems with MC 5

    I've got the same problem.  Lack of authorization limits lots of things. 

    My guess would be that the problem lies somewhere between the soundcard and how avid is using/reading from the soundcard ... but ... that's only a random guess.

    Re: Major audio problems with MC 5

    When adding or replacing an audio clip in the timeline a couple of times, I've noticed there was no sound on playback.  (PC, MC 5.0.1)  The audio mixer still shows 0 VU, and bumping the level control brings back the audio.

    This only happens occasionally and not sure what the circumstances are to reproduce it.

    Weird.

    Re: Major audio problems with MC 5

    I replied earlier (see above) about spotty audio playback, such as random dropouts and sudden loud/soft audio issues.

    I wanted to update this thread on my troubleshooting to say that the update to MC 5.01, and the disabling of Realtek HD Control Panel still did NOT solve the problem.

    I also tried opening the same project on a dual-core Gateway laptop with Vista 64 Home that has Conexant audio (not Realtek). And although audio playback was much better at first, eventually the same problems began surfacing. Albeit slightly less frequently it seemed.

    I checked the specs for a few of the officially qualified Avid workstations from Dell and HP, and Realtek audio is in use on those too, so Realtek codecs would not seem to be contributing to this problem. I'm beginning to think this is an Avid bug that will eventually (hopefully) need ot be addressed. Please post if you're in a similer boat.

    Re: Major audio problems with MC 5

    I'm also struggling with intermittent and odd audio problems in my MC5 project. Sometimes everything is fine. But most of the time, there are entire tracks that just don't want to work. It's odd, as if those tracks somehow aren't "activated". I can hear tracks one and two, but not three and four, or I can hear three and four, but not five and six, etc. 

     

    This is a project that I moved from MC 4 to MC 5. I have a feeling it has something to do with that, but I've been using MC 5 for a bit now and don't want to go back to 4. 

     

    Anyone have any clues as to what's going on here?

    Any other users with these issues please report in IF you can reliably replicate a specific malfunction over and over again, and please provide your correlations when you do. We need to establish patterns that Avid engineering can replicate. The more experimenting and detail you can provide, the better.

    Re: Major audio problems with MC 5

    Hi Larry-

    There's another thread here http://community.avid.com/forums/t/88008.aspx

    ...with a few more recent and varied posts of essentially the same audio issues. The really interesting bit is that Mac users are chiming in, as well as Nitris, Symphony, Mojo SDI and software only. 64-bit OS (Vista 64, Win 7 64 and OS X) does seem to be a common denominator though...

    Speaking from experience, the audio fluctuations are seemingly random and nearly impossible to reproduce with any consistency. But once it starts happening, it tends to keep happening.

    And until users can replicate the problem reliably and consistently on supported systems, I cannot escalate it.

    Re: Major audio problems with MC 5

    I'm using MC 5.03 and having similar audio problems as described in this post. 

    I have the Nitris with a 2x3 GHZ Quad core Intel Xeon Mac with 4GB of Ram. 

    Here's what I'm doing.  I'm linking to Cannon 5D quicktimes on a firewire 800 drive.  The drive does not supply it's own power.  I got it form the client so I'm trying to use it instead of moveing 250GB to our local drives.  I think this may be part of the problem, not sure.

    I've cut 3- 2 minute sequences with music that was imported from uncompressed wav files.   These are basically interviews.  In order to get the synced audio I first made reference movies in FCP.  I know that's probably an issue to.  But should it be? 

     

    Basically, I didn't have time to go back and resync all these shot so I decided to take advantage of the new AMA capabilities.  The cool thing was all 5 tracks of audio from FCP came over with the Quicktime references. 

    The uncool thing is I have this audio play back problem.  The audio seems to lag behind the video and thus I get some audio hits as well.  Once I export the final version I'm fine, so this will not affect the final output.

    The problem is explaining the problem to my client.  I can deal with it to save a bit of time, but maybe there's an answer I'm not seeing that's out there.

     

    If so please let me know. 

     

    Thanks.

    DL

    Sorry but how it is possible to link H264 from a drive that has no power?

    H264 are very heavy files.

    A drive that is not self powered is being powered from an external power supply, like a Seagate 600.

    If he means that OK.

    But again H264 should not be linked and worked by there.

    Even on my 1TB/s RAID 0 they are failing to be smooth.

    Re: Major audio problems with MC 5

    I noticed that if I render a color effect on a top track the performance does get better, but it still lags. 

     

    So am I right to think linking to H264 files is not perfected then?  It seems that the lagging happens on the cuts.

     

    Any suggestions ont his issue? 

     

    Thanks.

    I am still on 5.01 and experiencing NO audio playback when I drop an audio file in the timeline. This is random and most of the time, when I import the audio and preview, it plays fine, but as soon as I drop it in the timeline and hit play, the VU remains at 0 and the progress bar seems to be moving, and it also locks out the preview audio. In a nutshell, as soon as I drop the audio in the timeline, all audio do not play
