Cl1 USB audio interface sound OK Win10, no sound win7 (dual boot)

Hi,
Cl1 always worked great on win7SP1. After installing a dual boot (with win10) Cl1 is working OK on win10 but not any more on win7(nor DAW, VLC media player, or youtube sounds are working). i reinstalled driver under win7 . This installation was OK. But no sounds in the speakers (same knob settings as win10). Please help :slight_smile:
