Sound from Crystal light

Anyone know how to get sound out of the DMAS speakers on the Crystal Light? From what I picked up I need to select 7.1 surround sound in the Pimax speakers, but that option isn’t available to me.

Thanks, LouP

Well, I re-installed the smas speakers but still have issues. I had to change the refresh rate to get the sound to start working but it didn’t last long before it cut out again. I ran the windows troubleshooter, and it reported a driver problem, but it couldn’t fix it. I see a lot of people having sound issues but can’t find any solutions. I am wondering why I did not see any of these issues in all my research before purchasing the unit. I’m not sure I would do it again knowing what I know now.
