I keep getting this error on one certain project I am working on. It comes and goes and is really getting obnoxious! Anyone got a clue what it could be?
"The playback device Microsoft Sound Mapper does not exist."
If you have a look at the preferences, under the Audio Device tab, it might be set to Microsoft Sound Mapper (mine is). Change it to whatever your sound card is.
I can't be certain it will work, but I had a similar issue when I removed my Creative Xi-Fi card - errors regarding ASIO. (It seems that the Creative uninstaller doesn't uninstall.)
Also if you are using a DAW system like studio one to create your audio tracks for the videos and that program is open it will override your sound and cause it to give you the same error reading if you open sony vegas
