Ubuntu: No audio through HDMI with Gigabyte Brix



Question:

Newbie to Ubuntu (13.10 x64 desktop) and have been trying to get audio to work on a Gibabyte Brix (GB-BXi3-4010) through HDMI but no go. If I plug into the standard headphone jack audio works no problem. By default Ubuntu views HDMI as a possible audio output in the sound settings but will not output. Installed ALSA mixer and it will show Intel Haswell as a tab but no output options. Missing driver?

aplay -l output:  **** List of PLAYBACK Hardware Devices ****  card 0: MID [HDA Intel MID], device 3: HDMI 0 [HDMI 0]    Subdevices: 1/1    Subdevice #0: subdevice #0  card 0: MID [HDA Intel MID], device 7: HDMI 1 [HDMI 1]    Subdevices: 1/1    Subdevice #0: subdevice #0  card 0: MID [HDA Intel MID], device 8: HDMI 2 [HDMI 2]    Subdevices: 1/1    Subdevice #0: subdevice #0  card 1: PCH [HDA Intel PCH], device 0: ALC269VC Analog [ALC269VC Analog]    Subdevices: 1/1    Subdevice #0: subdevice #0  card 1: PCH [HDA Intel PCH], device 1: ALC269VC Digital [ALC269VC Digital]    Subdevices: 1/1    Subdevice #0: subdevice #0  


Solution:1

I have Kubuntu 15.04. Also did not have audio, just went to System Settings/Multimedia. I changed the preference for audio playback to HDMI for all categories. Sound works now without problem.
