Hi

First I want to thank the community for bringing us this AWESOME OS.

I am having analog output from ATI RS780 High Definition Audio Controller with Realtek ALC888. I want to use HDMI output WITH NO LUCK.

1) I have:
Code: 
snd_hda_load="YES"
into /boot/loader.conf for the driver to load.

2) some output:

Code: 
bsd# cat /dev/sndstat
FreeBSD Audio Driver (newpcm: 64bit 2009061500/amd64)
Installed devices:
pcm0: <HDA ATI RS690/780 HDMI PCM #0 HDMI> (play) default

pcm3: <HDA Realtek ALC888 PCM #2 Digital> (play)
pcm4: <HDA Realtek ALC888 PCM #3 Digital> (play)

No audio from HDMI only Analog. Any suggestions would be appreciated.
 
HDMI audio from a video card requires support from the video driver in addition to the sound driver. xf86-video-ati (aka the 'radeon' driver) does not provide this support on FreeBSD. Theoretically, xf86-video-radeonhd provides this support, but I've never heard of anyone actually doing this on FreeBSD.

Meh. I answer a lot of questions here and on other forums, I certainly don't remember every post I make and every person I help. I also saw no reason to to search the forums since I knew (and provided) the correct answer.

I did see the older posts, but I don't have xorg.conf. It starts in gnome without it. Thanks.
 
You can create an xorg.conf file with 'Xorg -configure'. Just be sure to change the driver from 'ati' or 'radeon' (not sure which it will choose by default, but it will be one of those) to 'radeonhd' and add the options mix_room mentioned in his post.
