Sandbox directsound problem

[REDACTED]

Hello!, I have a problem; it seems that whenever I try to run an application with sandbox I get a generic error saying that directsound device can not be found. Obviously all drivers are up to date and everything function properly out of sandbox. The sound card is the one integrated in the Asrock Z170M-ITX with a realtek chipset. Applications that don't require a sound card work fine.
Any ideas?
