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?

Sorry to jump in on your conversation Gary but I am also doing some bits
and pieces with meta-raspberrypi myself to test out my new-ish RPiv2.

I'll have a look at changing the kernel configuration here later, but I
did also try changing TEST_MODE in the config.txt which is billed as
giving analogue audio and video out at startup. Sure enough I hear the
startup beeps.

Perhaps this would enable you to verify the hardware is working too?

The docs would seem to indicate that it should output a/v for the
configured number of seconds whereas I see this continuously until I
power cycle, but maybe that is a typo.

Verified - this works.  Still no sound when I boot Poky/Yocto.

Have you tried audio output from Linux?

OK that's something then. I'm in the middle of some i.MX6 builds at the
minute but will look at this with the meta-raspberrypi kernel later and
come back to you. I suspect I will see the same as you.

I don't have anything capable of HDMI audio about here so will output a
wav file or something to the analogue jack. What's your simplest test case?

I might also have a look and see if I can get anything out of the
GStreamer1.0 audio/video playback as I'm looking at that too at the minute.

Use gstreamer:
   # gst-launch audiotestsrc ! alsasink

I think I tested sound with omxplayer on rpi2... this is pretty strange.

I just tried it with omxplayer - still nothing, sorry.

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?

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

Would it be possible to share your [bootable] 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

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.

Indeed, this does work - tested on RaspberryPi and RaspberryPi2.

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
bobs here which might help

http://raspberrypi.stackexchange.com/questions/22708/is-there-some-trick-to-getting-aplay-audio-output-working

I'd be wont to try

|amixer cset numid=3 2|


For starters to try to force HDMI output

Some other bits and pieces on ALSA in there I see, which might be relevant

Cheers, Alex
