I just upgraded to Movie Studio 16.0 Platinum. My biggest problem is the audio playback. The music track skips, stammers, cuts out, jumps back and forth. It really sounds terrible. In the Preferences menu, the Audio Device is Microsoft Sound Mapper. I haven't made any changes to anything. I'm running Windows10 and, until the upgrade, never had this problem. Help!
Instead of Mapper, use the ASIO driver for your audio device in Vegas Preferences.
It may say Direct, 3d, or HD Audio, but it won't say Microsoft. Post back and let us know if it makes a difference.
I tried switching to Direct Sound Surround Mapper. No change. I've also got the option of Window Classic Wave Driver. Same result. The good news is I've plenty of time to figure this out. It's not as the estate of Stanley Kubrick is involved and has given me a deadline. It's the weekend - there are other things to do.
