No sound, or strange permanant noise like "trtrtrtrtrtrtrtrtrtr"

[Tchey]

Hello,

I have some troubles playing Starmade (Windows 7 -64). The sound is terrible, there is a kind of noise after a few seconds or minutes ingame. I've updated my drivers, and i did the copy/past .dll according to the small help screen at the Launcher Sound Options, but nothing has changed.

I've already tried to delete and reinstall the game a few times, and force download etc.

I could play without sound but it's not very enjoyable.

A few months before, i tested Starmade a little, and i didn't get this problem (same computer).

What should i do ?

Thanks
