Fedora 17 no sound from HDMI

I am running Fedora 17 on a Dell Latitude E6520. The default sound works just fine, but I can't get any sound out of the HDMI output when I have it hooked up to my tv.

aplay -l

Code:

**** List of PLAYBACK Hardware Devices ****

card 0: PCH [HDA Intel PCH], device 0: STAC92xx Analog [STAC92xx Analog]

  Subdevices: 0/1

  Subdevice #0: subdevice #0

card 1: NVidia [HDA NVidia], device 3: HDMI 0 [HDMI 0]

  Subdevices: 0/1

  Subdevice #0: subdevice #0

card 1: NVidia [HDA NVidia], device 7: HDMI 1 [HDMI 1]

  Subdevices: 0/1

  Subdevice #0: subdevice #0

card 1: NVidia [HDA NVidia], device 8: HDMI 2 [HDMI 2]

  Subdevices: 1/1

  Subdevice #0: subdevice #0

If I run

Code:

aplay /usr/share/sounds/alsa/Front_Center.wav

without specifying the sound card, it plays through the internal speakers just fine. If I try to specify the sound card with something like

Code:

aplay -D plughw:0,0 /usr/share/sounds/alsa/Front_Center.wav

which to my understanding should play it through the internal speakers just like when I did not specify the soundcard, I get the following error:

Code:

aplay: main:696: audio open error: Device or resource busy

Any clues what I am doing wrong? Thanks

I had some sound problems on my system, when using HDMI, and during the process of trying to solve the problem I noted that my bios had a setting related to HDMI audio output...SPDIF_OUT Mode Setting, [SPDIF output] sets SPDIF audio output, [HDMI output] sets HDMI audio output.

Your problem may be quite different, but it maybe worth a look to see if your bios has similar settings.
