No way to set the sound playback from HDMI on Panda ubuntu image.

Tom, can someone from the MMWG verify this bug?

Yup!

I can confirm the issue when running with Panda 4460. I also don't get any sound from the device.

On my 4460 Panda ES, going into settings I see HDMI for audio output but I see no way to change over to the audio jack. This is a regression.

Please note, I'm using the linaro-lt-panda_20120524 hwpack not the -x11 varient, that hwpack from 523 I was unable to successfully boot my panda es board.

I used to test pulseaudio by speaker-test. But for GUI interface, I think there's libpulse0 version mismatching in those programs. All those programs need repackaged with libpulse2.0, including gstreamer0.10-pulseaudio and certain GUI programs.

indicator-sound and gstreamer0.10-pulseaudio packages are now rebuilt
against PA2.

@Botao
I had same results and after debugging, I found an issue of sound-nua section of gnome-control-center, that it handles pulseaudio port as single direction. But in fact I created bi-direction port from ucm configs in pulseaudio. So I will consult some upstream audio specialist and give the final fix.

@Botao, it needs QA verification.

Seems to be fixed in the 12.06 RC:

http://snapshots.linaro.org/precise/images/ubuntu-desktop/247/linaro-precise-ubuntu-desktop-20120626-247.tar.gz
except - the default seems to be jack, not hdmi, even if nothing is plugged into the jack. I can switch it now by going to the audio settings though.

On hardware pack:

with ubuntu rootfs:

http://snapshots.linaro.org/precise/images/ubuntu-desktop/247/linaro-precise-ubuntu-desktop-20120626-247.tar.gz

There is still no option to select the HDMI as an audio output, refer to attachment to get the desktop screen shot.

I get the same results as Paul:
- default is jack
- I have OMAPHDMI and can switch to it

This is weird because you can see the desktop screen snapshot on comment #14. Perhaps something wrong in my Panda hardware?

Botao, are you using the DVI or HDMI output during your test? The HDMI one is the output closest to the USB hub.

Otherwise please post your full dmesg so we can investigate the issue.

Sound over HDMI works well now.

Same behavior on Panda 4460 board.

I have a different experience...

On my system, it works fine.
In sound settings, I see:
PandaBoard 3.5mm Headset playback and capture
and
Analog Output/OMAPHDMI

They don't auto select based on plugging in the headphone, but when I manually select them, I can get audio over hdmi for the hdmi one, and over headphones for the 3.5mm one.

This feature works well on Panda 4460 board with same hardware pack & ubuntu rootfs image.

For Panda 4430 board, observed same behaviour as comment #27 on Linaro ubuntu pre-built image:

http://snapshots.linaro.org/precise/pre-built/lt-panda-x11-base/219/lt-panda-x11-base-precise_ubuntu-desktop_20120803-219.img.gz

Because my Panda 4430 board seems has some hardware issue, at least the 3.5mm audio jack is broken, and this feature works well on my Panda 4460 board, therefore, this may be caused by my hardware, not defect in image.

Also, according to the comment #24, this feature works well on Paul's Panda 4430 board.
