                      <br>
                      I tried this patch (which downloaded very
                      strangely using Thunderbird)
                      <br>
                      and
                      <br>
                      the
                      <br>
                      kernel rebuilt fine.  I now have the audio
                      detected, but still no sound
                      <br>
                      :-(
                      <br>
                      Again I've tried the internal (phono) speakers as
                      well as HDMI audio.
                      <br>
                      <br>
                      Just to prove a point on the [brand new] hardware,
                      I installed OpenELEC
                      <br>
                      (XBMC)
                      <br>
                      and it works fine using the HDMI audio.  Sadly
                      when I tried Raspbian
                      <br>
                      and
                      <br>
                      Ubuntu
                      <br>
                      there was no sound either...
                      <br>
                      <br>
                      Were you (Andreas) able to get any sound with this
                      patch?
                      <br>
                      <br>
                    </blockquote>
                    Yes but I have used 3.5mm sound output - Should have
                    mentioned that in
                    <br>
                    commit. I guess there is to enable something else in
                    kernel config for
                    <br>
                    HDMI. Will look into that
                    <br>
                  </blockquote>
                  <br>
                  I've tried the 3.5mm jack as well but nothing seems to
                  come out.
                  <br>
                  I even tried booting with the HDMI missing (powered
                  off) in case
                  <br>
                  that was causing some confusion.
                  <br>
                  <br>
                  Did you make any changes to config.txt to get this
                  going?
                  <br>
                </blockquote>
                No
                <br>
                Have my standard xfce-image with xfce4-mixer and as
                mentioned out of
                <br>
                the box: I can hear sound / change volume...
                <br>

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

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

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

          Circling around this a little, hello_audio built out of

        OK I got some life from GStreamer and my RPIv2
        <br>
        <br>
        Install amixer
        <br>
        <br>
        modprobe snd_bcm2835 (or presumably use an image with audio
        built-in)
        <br>
        <br>
        amixer cset numid=3 1 (to set output to audio jack)
        <br>
        <br>
        gst-launch-1.0 audiotestsrc ! alsasink
        <br>
        <br>
        I get a tone out of the audio jack. So some kind of audio
        routing defaults issue.
        <br>
      </blockquote>
      <br>
      Indeed, this does work - tested on RaspberryPi and RaspberryPi2.
      <br>
      <br>
      Now, to figure out how to make audio over HDMI work.

    I don't have HDMI audio kit with me here but there are some bits and
