Right after the latest Windows 10 update, my Audacity (latest version) started adding a lot of crackling into my waveforms. I record in Reaper and do a few adjustments in Audacity, because they do them better. The sharp popping and crackles are not always in the same places and a change in the interface host, buffers, etc. makes no difference. Really annoying.
Anyone else have this? Is it a coincidence that it happened right after a Win 10 update?
