While what I have is working, I wouldn't mind having info in case it
stops working or I need to change my video player. I don't have a card2
but I do have a card0 and card1. I'm including both since I'm not sure
what is what. Plus it may help someone else. Since I snipped previous,
this is the setting for my TV. alsa:device=hw=1.7
