Good news, no more stuttering on vista :) Thank you for your guidance. In fact Ptime set to 20ms fix it. With only Dsound change it is still stuttering. I test Ptime change on XP and sound quality is good. I have to make more test to say if sound quality is better under XP. Tested under Vista 64 bits, DirectX version 8.
