Thanks. I was just waiting to redo my website, edit the video, put the pics together, etc etc but life and freelance work get in the way. Man, I could use a clone right about now :P

Also interested in the UDOO setup instructions so thank you. A bit OT but, Dan, love your work (that "onward to mars patch" is awesome) thanks for the links. I think people should post more of this sort of thing to the list, celebrate what we make. =)

I will do that later tonight when I boot the udoo and pull my run scripts off of it. I'll post everything to GitHub so we can share resources.

Hi Dan,
Thanks for sharing these notes. They arrived in my inbox to coincide nicely with the delivery of my quad Udoo this morning! It would be great to see a full writeup of your Udoo setup at some point as I think many people will want to be doing a similar thing.
All best,
Jamie

Heres a trim of my notes:
Enable realtime audio priority (if you haven't done it already):
sudo su -c 'echo @audio - rtprio 99 >> /etc/security/limits.conf' sudo su -c 'echo @audio - memlock 250000 >> /etc/security/limits.conf' sudo su -c 'echo @audio - nice -10 >> /etc/security/limits.conf'
I disable pulseaudio. Make sure pulseaudio does not respawn itself (from http://voices.canonical.com/david.henningsson/2012/07/13/top-five-wrong-ways...):
echo autospawn=no > ~/.pulse/client.confAlso add the following to ~/.bash_login to kill pulse audio if it's running on login:
# kill pulse audio if it was spawned pulseaudio -kI'm not looking at the udoo run script, but I'm pretty sure I'm using the following with the US-25EX USB soudcard:
pd -rt -nogui -alsa -audiodev 5
Use pd -listdev to get the device list from alsa. I chose 5 as the first 4 (from memory) are 1-2 (built in hardware & plugin) & 2-3 (HDMI audio hardware & plugin). 5 is the USB hardware alsa dev.

hey dan,
unfortunately i’m in switzerland :-)
would be great if you could post your setup somewhere or send the infos! i compiled pd from source as well. i start it from console (with -rt) and it works without problems with the builtin sound card. maybe the cheap card from dx.com just does not work properly with udoo. but please post your setup.
thanks

The dedicated USB controller makes these guys work as compared to an RPI where I can't get full duplex without tons of dropouts.

Jack is needless overheard unless you want to work with other Jack-enabeld apps.
