Doesn’t happen for me on the Focusrite Scarlett 2i2.
Might depend on the patch you’re opening into, or maybe it’s your audio interface.
Is your interface set to the same sample rate as Rack, or is the sample rate on the interface being changed by Rack when it loads whatever Audio module you’re using?
What have you tried doing to localize your issue? (different audio i/o, different patch, different sample rates, different starting interface settings, etc.)
I’ve had it happen with two different RME interfaces. Fireface 800 and the new Fireface 802 FS. It’s not a sample rate change as I’m running everything at 44.1khz (Windows, my DAW, and VCV Rack).
I had an unhelpful “power saver” option in my Linux system’s audio driver. Sometimes the thing would make a loud THUMP every few seconds when it decided to power my speaker system up and down. I’m sure it worked fine on the developer’s system and saved him several pennies of electricity per year. These are the kinds of system-level things you sometimes have to spend hours (or days) researching and fighting with.
I never had that issue until about a month ago, no idea what changed for it to start popping.
I know it depends on the patch it loads (at start up rack as well as later on) but don’t know why.
When loading rack into my daw (renoise) as a new vst it doesn’t load last patch automaticly so it doesn’t pop untill I load up one of those popping patches.
Opening a saved song wich has a rack popper patch will pop as well regardless of settings in either daw or rack or if the vst is muted in the daw project.
