Maybe the "affected" guys can post some clips, when the sound is worst - so others have a comparison to find out, if they are infected too. Is it worse while using the new delays (someone has reported crackling issues)?
Have you tried lowering the Master Volume below 50 % - and compensate volume carefully with your mixer / soundcard??
Really hope you can get it fixed soon!
The new delays also seem to introduce artifacts at extreme settings, but these aren't the same. Not an issue with master vol either. But yea it'd be good to have more clips.
