Hi,
I've installed lubuntu 12.10 on my fit-pc3 and cannot get any sound over the HDMI port.
I see that the device is recognized -- aplay seems to work correctly (with -D hwplug:1,0) although no sound is heard.
Alsamixer reports all output values at 100% and unmuted. (Yes the TV volume is up high.)
Any suggestions?

More data, if it helps:

Re: Ubuntu [lubuntu] / no sound over HDMI
OK, revised question. Also a continuing document of where I am for future readers with the same problem.
First, thanks to this page (http://superuser.com/questions/53957/wh ... ich-to-use) I've learned about sound device aliases, which is good because after I posted the above I found that the command I had previously used didn't work anymore...
But the following command consistently succeeds:
Which alias to use I determined by looking at the list of aliases given by aplay -L :
And experimenting with each of the ones that showed HDMI in the paragraph.
So the resulting question is:
How do I incorporate the information that I *always* want any sound-generating program to use "plughw:CARD=Generic,DEV=3" as the sound device into an .asoundrc file?

Discard all samples (playback) or generate zero samples (capture)

Direct hardware device without any conversions
plughw:CARD=Generic,DEV=3

Hardware device with all software conversions

... and so on and so on...

Re: Ubuntu [lubuntu] / no sound over HDMI
To enable HDMI output on Ubuntu 12.10, try to install pavucontrol
and select appropriate profile under the Configuration tab.
Don't forget to reboot your system
Code: Select all
sudo apt-get install pavucontrol
Don't forget to reboot your system

Is pulseaudio required for HDMI audio? I don't currently have it running.gabrielh wrote:To enable HDMI output on Ubuntu 12.10, try to install pavucontrol
Re: Ubuntu [lubuntu] / no sound over HDMI
The pavucontrol will install all the necessary HDMI related libraries

I have installed pavucontrol and it has not changed anything.gabrielh wrote:The pavucontrol will install all the necessary HDMI related libraries
Previously, I could run
Code: Select all
aplay -D plughw:CARD=Generic,DEV=3 /usr/share/sounds/alsa/Front_Center.wav
I just want to tell alsa to use HDMI. How to do that?
Re: Ubuntu [lubuntu] / no sound over HDMI
You should choose one of the HDMI profiles in the Configuration tab
