Currently in v19 build 643. I cannot get Vegas to play 100% nice with ASIO audio. I'm using RME audio which are the gold standard of ASIO drivers, and work flawlessly in Magix Sequoia, Reaper, Pro Tools, Nuendo on the same machine.
Issue one. If I'm using ASIO with Vegas, certain Normal operations in the application glitch out the audio (at all buffer sizes). Simple operations like vertically scrolling tracks, or mousing around In the Project Media. Does not happen with Windows Audio driver settings.
Issue two, related. Having become frustrated with the ASIO performance, if I then go to change the audio driver model in Preferences, it often doesn't actually change once I click apply. Changing driver models and channels is unpredictable, especially going back to ASIO from WDM. The last WDM setting persists. Often, I have to trigger some state where I get a pause and an hour glass icon for 10 seconds, for the driver model or channels to actually change.
If anyone has any helpful tips on these issues, I'd appreciate hearing about it.
