Quick Tip: Audio playback and USB Mic problems in Captivate 4

16

Many people are reporting problems with Captivate 4 and Audio playback and recording. Adobe posted a fix on their blog and apparantly it does help some people.

I posted the solution below so if you have these problems try it out and see if it works for you.

We found that in some of Vista machines with Real tek or Sigma tel sound card audio inside captivate doesn’t play back. Some customers who use USB mic for recording narration also observed that device is not getting detected by Captivate. These issues were reported more on Vista and we have one solution to address both the problems. – replacing the audio dll’s , Steps

Close Captivate 4 if it is open.
Download the file kept at
https://share.acrobat.com/adc/document.do?docid=a14e1bd9-dc10-4456-9cd2-44489809b78e
Go to your Captivate 4 install folder (ex: C:\Program Files\Adobe\Adobe Cativate 4)
Rename nsaudio.dll as nsaudio.dll.bak or anything which doesn’t have a dll extension
Copy the file from step 2 to Captivate 4 install folder
rename it as nsaudio.dll
Start Captivate 4
Try to play the audio /use USB – it should go fine

In case you can’t download the file from the above mentioned location I put up an alternative download link here (right-click to save file): http://www.cpguru.com/demonstrations/NSAudio_modified.adobe

  1. Thank you for sharing this information! This is exactly what we needed to fix the problem.

  2. Any idea why I can’t find or access the file you reference in the link above? I’ve seen it on several sites but can’t access it. I’m told that the file cannot be found or I don’t have permission.

    Hi Amy,

    No clue why you can’t access the file – I just tried again and it works fine for me.

    Right now I am in the process of re-doing this blog, but once I’m finished with this I will put the file up here for direct download as well.

  4. admin,
    I too tried to download file. When I hit the download button, the message appears that the file is not available from the site. Has it been removed?

  5. Hi Teresa,

    No the file is still available – I just tried now and I don’t have any problems with downloading it.

    Have you updated your Captivate 4 with the latest update? I would think that this issue is also addressed through that patch.

    Download it from Captivate – Help – Updates.

  9. Con,

    The original nsaudio.dll file is located in your Captivate 4 install folder (ex: C:\Program Files\Adobe\Adobe Cativate 4)

  11. Hi Kathirvel,

    To me it sounds like it could be an installation issue. I use CP4 on a XP32 bit system without any issues and the patch didn’t (afaik) address any recording issues. Try and reinstall Captivate 4 on your system and see if that helps.

  12. Hi Jean-Luc,

    Captivate 4 is unfortunately not running very well on 64-bit Vista systems. Try and run Captivate 4 in XP compatability mode and see if that helps.

  13. Thanks – I too was getting very cross about this. My Logitech Ultra videocam mike was working perfectly well with all other Adobe products on Vista, but not Captivate. It works fine after replacing the nsaudio.dll file. A pity Adobe can’t post this solution on their website a bit more prominently ?
