After installing a new OS on a new lenovo ideapad 710s I imediately wanted to test sandboxie. Everything workes fine except the sound, neither with films on any media player (VLC, SM player, Media player) nor on youtube with either firefox, opera or chrome. The devices don´t even turn up in the speaker mixer, where you can always find it in the host. All driver is working fully normal in the host, there surely is no mistake with the driver. In all my other computers (with Win 7 ultimate) I never had a sound problem so far.
Maybe someone can help me on that. Thanks
