ATI HDMI Audio Not Working

Hi. I'm trying to get my ATI HDMI audio working. I've followed the instructions at https://wiki.archlinux.org/index.php/ATI#HDMI_Audio and running "aplay -D plughw:1,3 /usr/share/sounds/alsa/Front_Center.wav" outputs no errors nor any sound on my TV. Adding radeon.audio=1 to my syslinux.cfg and rebooting results in no changes.

I have also followed the instructions at https://wiki.archlinux.org/index.php/Ad … s_Not_Work which also resulted in no changes. One note though. When I select my HDMI sound card in alsamixer, there is only one sound bar shown entitled S/PDIF. I can mute or unmute it but not increase the volume from 0. No idea if this matters.

Also, I'm using the xf86-video-ati driver.

aplay -l

**** List of PLAYBACK Hardware Devices ****
card 0: SB [HDA ATI SB], device 0: ALC888 Analog [ALC888 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: SB [HDA ATI SB], device 1: ALC888 Digital [ALC888 Digital]

card 1: Generic [HD-Audio Generic], device 3: HDMI 0 [HDMI 0]

Any help would be appreciated, I'm stumped and I would love to get this fixed so I can get xbmc working and fully drop windows.

Re: ATI HDMI Audio Not Working

I use an nvidia card so this might not apply to you but using alsamixer i have to press F6 and then select HDA Intel even though my card is nvidia (once in, it will read Card: HDA Intel, Chip: Nvidia MCP77/78 HDMI)
Then press F5 to see everything, input and output. Then unmute spdif and that takes care of that.
Then, to save your settings, as root:

alsactl store

Re: ATI HDMI Audio Not Working

In alsamixer, after hitting F6 and selecting HD-Audio Generic (once in it reads Card: HD-Audio Generic, Chip: ATI R6xx HDMI), I see one sound bar, S/PDIF, that I can mute or unmute but which I can't increase or decrease the volume of. Pressing F5 shows no visible sign of change. S/PDIF is and has been unmuted. Not sure what else to do. =/

Re: ATI HDMI Audio Not Working

Might be an obvious question but have you chosen your HDMI card as the device to use in your sound settings? for example if using gnome3 it would be under sound settings and then the "hardware" tab.

Re: ATI HDMI Audio Not Working

I'm not entirely sure how I would go about doing that, or if I would need to considering the command I run to test the HDMI audio...

aplay -D plughw:1,3 /usr/share/sounds/alsa/Front_Center.wav

... is, I'm assuming, sending the sound directly through my HDMI due to plughw:1,3 specifying that. I put it as 1,3 after running aplay -l.

Also, I'm running xmonad, not gnome/kde, so I don't know what settings I can change beside what's in alsamixer.
