Sorry for yet another digital audio thread.<br>
<br>
I can't get any audio whatsoever to go through my HDMI connection.<br>
Here are some details of my setup:<br>
- Gigabyte GA-E7AUM-DS2H motherboard<br>
- MythDora 10.21 (kernel 2.6.27.9-159.fc10.i686)<br>
- alsa 1.0.20<br>
- nvidia driver 180.51<br>
- Vizio TV model VW32L<br>
<br>
The alsa version is a little weird. "yum list alsa\*" shows version<br>
1.0.20-1.fc10 of alsa-lib.i386, alsa-lib-devel.i386, and<br>
alsa-utils.i386, yet "cat /proc/asound/version" gives 1.0.18a.<br>
<br>
I even went so far as to disable onboard audio in the BIOS setup,<br>
leaving HDMI audio enabled. Here are the results of aplay:<br>
<br>
$ aplay -l<br>
**** List of PLAYBACK Hardware Devices ****<br>
card 0: NVidia [HDA NVidia], device 3: NVIDIA HDMI [NVIDIA HDMI]<br>
Subdevices: 1/1<br>
Subdevice #0: subdevice #0<br>
$ aplay -L<br>
hdmi:CARD=NVidia<br>
HDA NVidia, NVIDIA HDMI<br>
HDMI Audio Output<br>
null<br>
Discard all samples (playback) or generate zero samples (capture)<br>
<br>
Alsamixer shows just one control, IEC958, and I have unmuted it.<br>
<br>
No audio with Myth. No audio with something like "mplayer -ao<br>
alsa:device=hdmi -afm hwac3 1071_20090620215900.mpg". No audio with<br>
"speaker-test -D hdmi -c 2". I tried following Allen's tips in<br>
<a href="http://www.mythtv.org/wiki?title=AllensDigitalAudioHowto" target="_blank">http://www.mythtv.org/wiki?title=AllensDigitalAudioHowto</a> (but at 2:00<br>
in the morning I'm not sure I tried every combination). Pulseaudio<br>
appears not to be installed except for pulseaudio-libs.<br>
<br>
Interestingly, if I ctrl-alt-F2 to switch into a console window, aplay<br>
says there are no devices. I wonder why is that?<br>
<br>
Any suggestions on how to proceed? Does anyone have positive<br>
experience with HDMI audio on this motherboard, the Gigabyte<br>
GA-E7AUM-DS2H?<br>
