I just set up my Mega SD for the first time. Very excited! I have it connected to a Mega SG running jailbreak firmware that is up to date as of 8/22/19. (And running Mega SD's latest firmware as of 8/22/19.) So far I am not getting "CD" audio in this configuration. Just Genesis audio. Things I have tried: made sure Mega SD's volume is up (it's at 90%) in the menu. Made sure Mega SG's cartridge audio is enabled. What else could I try to resolve this?
