English Amiga Board - View Single Post - When i Enable Vsync, audio is not synchronized

Hi all,

i read a lot of topics with similar issues. I would like to explain my issue.

Winuae 1.4 stable version
Filter : Direct3d , bilinear 16bit
Fullscreen + Vsync (to get the scrolling smooth without tearing)
Soundbuffer : 4
LCD Samsung 930bf : 60hz (the only one option available, i think that i can't set 50hz with this LCD... i will try with powerstrip, i don't want to damage my LCD monitor)

With this configuration , the sounds is played just a bit later than video.

I think that the problem is related to the reresh rate, as enabling Vsync it is forced to 60hz, the audio and video runs with different speed (correct me if i'm wrong)

Firstly i would like to know if it's an expected behaviour and not a real issue.

Second i would like to receive feedback about this strange "workaround" i implemented. I set the audio buffer to "1" or "2" and it seems that now the audio and video are full synched. I think that reducing the sound buffer i could encounter some problems during the moments of major cpu workload.... It's already happened during a Session of Ruff'n'Tumble.

So if you reached this point

, i'd like to hear from you

Any chance to solve this issue? Should i come back to my previous CRT?
