That's because Launchpad only sends us your preferred email address when you login via OpenID. The next time we suck user data from Launchpad, it will notice these other email addresses can be linked to your Patchwork account and will do so. I've triggered a manual run now, so you'll see the extra email addresses there shortly. -- Guilherme Salgado <https://launchpad.net/~salgado>

Sound hardware device specifics for Linaro dev boards

by Kurt Taylor

Hi everyone, I am trying to assemble a reference for the sound device specifics for all the platforms. The catch is that I don't have all the dev platforms available to me. Here is where you can help! I have Panda and Beagle C4. I need everything else. If you have access to other platform(s), please do the following and email the output to me. With a Linaro image or Ubuntu image (an image with with pulseaudio installed), run the following: "pacmd list-sinks" and email it to me. You will get an output that resembles this: linaro@localhost:~$ pacmd list-sinks Welcome to PulseAudio! Use "help" for usage information. >>> 1 sink(s) available. * index: 0 name: <alsa_output.platform-soc-audio.analog-stereo> driver: <module-alsa-card.c> ... <lotsa stuff deleted> module-udev-detect.discovered = "1" device.icon_name = "audio-card" Thanks in advance!
