Audirvana has many audio settings. The issue of loud static when switching songs in Audirvana might be related to several factors. Here are some potential solutions:
1. Check Audio Settings: Ensure your audio settings in Audirvana are optimized. Try reducing the buffer size and adjusting sample rate settings.
2. Disable Gapless Playback: If enabled, try disabling gapless playback in the audio output settings to see if it resolves the issue.
3. Update Software and Drivers: Make sure both Audirvana and your DAC drivers are up-to-date.
I use Audirvana and like it very much. I suggest you investigate further to see what is going on. And maybe post this question on the Audiovana Community forum.
