(FIXED) No in game sounds

Im having trouble with the in game sounds. There is no music/sound in the menus or during the novel section of the opening game. There is however sound during the opening movie. Other games/programs i run have all their intended sounds. I have checked the options menu and all the sounds are turned up to max. This happens for both 999 and VLR. Anyone else having this issue and have had any luck fixing it?



Update: Installed on my 7 year old laptop i used for school and sound works fine. Old laptop is running Windows 7 and DirectX 11 as opposed to Windows 10 and DirectX12 on my desktop.



Update 2: Terr's solution of Installing OpenAL does indeed work. Thanks!
