  Video playback error message

  Posted by Stefan Voss on January 19, 2008 at 6:27 pm

  Hi there:

  When I hit the play button in the Vegas 7 editing screen to review an imported (previously captured) video clip I get the following error message: “An error occurred while starting playback. The device specified is in use.” No details are listed in the ‘details’ tab.

  For video capture I am using Canopus ADVC-55 as previously recommended. Works great but not I’m stuck not being able to replay what I previously captured. What do you guys think is the issue?

  Thanks in advance, Stefan

  Could there be some other device that has taken control of your audio card? Or firewire port? or something else? In this particular case I think I’d first look toward audio. Open the Vegas preferences and see what audio device is chosen and see if there’s any other options.

  Thanks Ed!

  I did remove the firewire from the soundcard port as you suggested. This seems to be a deeper issue however.

  Again, the exact error message occurs whether I hit play or use the ruler. The error message states:

  “An Error occurred while starting playback. The device specified is in use.”

  When you hit the ‘details’ tab the message you get reads:

  “The playback device Microsoft Sound Mapper does not exist”

  I found this thread discussing the same issue back in 2005:

  https://www.indietalk.com/archive/index.php/t-6157.html

  Unfortunately none of the recommendations within helped me isolate / resolve the issue.

  here a recap of some of the steps I took:
  – removed firewire from soundcard port
  – Installed latest versions of DirectX and WM Player (for what it’s worth)
  – Checked under ‘Prefences –> Audio Device’ in Vegas and made sure ‘MSFT Sound Mapper is selected. When I select my soundcard instead I get the same error message.

  Any ideas? What am I missing?

  Thanks again!!

  OK I figured it out 🙂

  Sometimes solutions are a lot closer than you think.

  When you get this error message try the following:

  1. Open Vegas
  2. Go to Options –> Preferences
  3. Click on ‘Audio Device’
  4. If ‘Microsoft Device Mapper’ is specified
  5. Change to ‘Windows Classic Wave Driver’ and for the three options below select your sound card
  6. Hit ‘Apply’, then ‘OK’

  This worked for me. The clip I captured was an *.avi clip BTW but that might not matter.

  Hope this helps others as well!

  Good luck.

  Hey yall,

  I had the same problem just now. I had also just opened after effects and it was sitting there with the “tip o’ the day” window.. waiting for me to click OK. I did, and tried to play the audio and it worked.

  weird…..
