Ben,
Fantasy Grounds asked what sound program, if any we use. https://plus.google.com/+Fantasygrounds/posts/RaVicGLdBVZ . I know they’re working on the next iteration of FG and has acquired Tabletop Connect https://www.fantasygrounds.com/forums/showthread.php?26242-SmiteWorks-is-growing!-We-have-acquired-Tabletop-Connect
I know a few people have given a shout out to Syrinscape as their player, if you haven’t already, reach out to them so we can have Syrinscape integrated in the next version of Fantasy Grounds.
