I tried this patch (which downloaded very strangely using Thunderbird)
and
the
kernel rebuilt fine.  I now have the audio detected, but still no sound
:-(
Again I've tried the internal (phono) speakers as well as HDMI audio.

Just to prove a point on the [brand new] hardware, I installed OpenELEC
(XBMC)
and it works fine using the HDMI audio.  Sadly when I tried Raspbian
and
Ubuntu
there was no sound either...

Were you (Andreas) able to get any sound with this patch?


Yes but I have used 3.5mm sound output - Should have mentioned that in
commit. I guess there is to enable something else in kernel config for
HDMI. Will look into that


I've tried the 3.5mm jack as well but nothing seems to come out.
I even tried booting with the HDMI missing (powered off) in case
that was causing some confusion.

Did you make any changes to config.txt to get this going?

No


            

            
Have my standard xfce-image with xfce4-mixer and as mentioned out of
the box: I can hear sound / change volume...


          

          
Would it be possible to share your [bootable] image?



          

            
What does happen if you start alsamixer - if it is installed on your
image?


          

          
alsamixer looks correct.

BTW, I've tried this on my RaspberryPi Model B and I don't get any sound
from it either :-(  Again, booting with test_mode=1 shows that the hardware
is working, just not in Linux. I'm sure I've tried this in the past with
success so I'm becoming more and more confused...



        

        
For sharing I need to create a smaller image - the current one
contains all stuff from meta-games, all browsers and more. Hope to get
that done tomorrow evening. What is the preferred way of sharing huge
files?



      

      
Circling around this a little, hello_audio built out of vc_graphics
works too over the audio jack

Alex



    

    

    
OK I got some life from GStreamer and my
      RPIv2

      

      Install amixer

      

      modprobe snd_bcm2835 (or presumably use an image with audio
      built-in)

      

      amixer cset numid=3 1 (to set output to audio jack)

      

      gst-launch-1.0 audiotestsrc ! alsasink

      

      I get a tone out of the audio jack. So some kind of audio routing
      defaults issue.
