I've had AFPD for over a week now and in the last few days the sound of the engines has deteriorated with stutters and a raspy, annoying type of tone. I"ve reinstalled AFPD and patched it again but it returned. Reinstalled sound card driver and DirectX9.0c, not change.
This is really annoying, other programs have normal sound. I hope someone else has seen this and found a solution. Performance was excellent until a few days ago, nothing was changed on my system that I can think of...
