Thanks for sharing your Audio System settings. Mine are the same, albeit with higher latency - I did try dropping the buffer down really low to match the latency and to see if that had any bearing, but it didn’t.
Interestingly though, after mimicking your settings the pop seems to have gone from the empty project (though still spiking), but its still popping like mad on larger projects. I’m not too concerned about the visual spike, but I do a lot of detailed sound design so I’m forever clicking around in the locater bar.
Thanks for your input. I’ll keep investigating.
