I have a Mac Mini 4,1. I get no sound at all except when I play through the internal speaker. Currently sound is supposed to go through the HDMI cable to the TV. I can see the HDMI output in the sound settings, but I get no love from the speakers. I've double checked the connection as sound works just fine in OSX. This is my first stab at using Ubuntu so ELI5 please.

Have you checked this: askubuntu.com/questions/285624/… –  Manuel May 30 '13 at 15:53
    
@Manuel He uses Ubuntu 12.04, not 13.04 as the user in the other question. –  Rodrigo Martins May 30 '13 at 16:05
    
The headphone jack works just fine. No sound through HDMI. And the power the TV on and off and every combination offers no love. –  Charliticus May 30 '13 at 21:19
    
I've upgraded to 12.10. And no luck. –  Charliticus Jun 2 '13 at 5:15

I have a MacMini as well, same 12.04 haven't solved the issue but have a workaround.

Whenever the monitor/TV is not on during the boot process the sound doesn't work. I normally reboot or put the computer into sleep mode and wake it up again. The sound then works. Mine works with OSX as well but with Ubuntu I need to go through this odd workaround.

@Charliticus you know that their are about 3 types of HDMI cables? They have versions like 1.3 1.4 or something, so maybe the cable? It's a slim chance, but I got caught on that once. –  Meer Borg May 30 '13 at 21:43
    
everything works fine in OSX. This is a dual boot installation. –  Charliticus May 30 '13 at 23:24
