Hello, on a Xubuntu 16.04 computer, i'm trying to play in live, from the speakers of the computer, the sound coming from the hdmi input port (an Android tablet is connected to the computer) of my capturing card (Blackmagic design Decklink mini recorder). I don't see the Decklink card in the Xubuntu sound options. The Decklink card works good in OBS when i record the stream in a file, the video and the sound are correctly recorder in the local file on the computer, but i never can heard the sound in Xubuntu while i'm recording, this is my problem. Thank you.
