Title: HDMI AUDIO PROBLEM
Post by: joerod on December 29, 2012, 08:44:42 pm

I have a M3N78-VM.  I used apt-get update and apt-get upgrade today and now I dont have audio (HDMI).  The command: aplay -D plughw:0,3 /usr/share/sounds/alsa/Front_Center.wav plays sound through the speakers, but no sound in xine and no sound in myth.  What are the correct steps to get it working? I already went through the avwizard again selecting hdmi audio and restarted various times.  This is on the CORE/Hybrid.

Thanks.

I would expect the m3n78-VM to not want a device assignment (3 in your case).

add "AlternateSC = 1" to /etc/pluto.conf without quotes. rm /etc/asound.conf /etc/X11/xorg.con* and reboot. This will take you to avwiz.

Though, again, would ONLY expect it to work with "AlternateSC = 0" (it will not exist currently in pluto.conf, which is equal to 0).

First of all thanks for the reply and for all the work you have done with hdmi audio in linuxmce. 

I'm a little confused about what you said:
     You would "expect the m3n78-vm to not want a device assignment"?
and:
     then "would ONLY expect it to work with 'AlternateSC = 0'...

not sure what you meant by that; anyway I edited /etc/pluto.conf and delete both /etc/asound.conf and /etc/X11/xorg.con*, then rebooted. This seems to have configured xine correctly (I have sound when using xine), but myth (tv) still has no sound.

aplay -D plughw:0,3 /usr/share/sounds/alsa/Front_Center.wav plays sound

-D = device
plughw = output to hardware (and resample based on DAC)
0,3 = Card 0, Device 3

I would expect that board to only work as hw:0

As your sound is now working, if you cat /etc/asound.conf I expect you will see that is what is being output to.

In myth, you will need to go to the frontend (not backend) setup. Go to General... after a couple of menus you will see Audio. Move it from "Default" to the hw:0,3 and change it to hw:0.

For some reason backspace in myth is interpreted as a "go back one menu"... so use delete. I am working on fixing this default problem in myth.
