[dun_panic]

Hi all, im having a problem here. it seem the mac version cant detect the blackmagic hdmi-sdi device. i cant select it through audio out preference in resolume. it shows only "HDMI" n i cant select it as output. ive tried it in windows version n its work like charm. It shows "hdmi blackmagic" not just hdmi. (((

Unfortunately, audio output via HDMI is not supported.

Apparently, it works on some boxes and setups, but it's not something we officially support.
