When I bought Samsung ARM Chromebook few months ago I had no idea about UCM profiles and [burnt speakers](http://marcin.juszkiewicz.com.pl/2012/12/10/how-to-fry-speakers-in-your-chromebook/) (left is dead, right is resting)…
This was good lesson. I learnt more about how UseCase Manager works, took profiles from ChromeOS and added them into Ubuntu so other users will be a bit more safe (due to lack of testers it took months to merge it into “precise” and “quantal” releases).
During last months I had discussions with some Debian, Ubuntu, Fedora developers about how to solve such problems and how to keep UCM profiles shared between distributions.
In meantime Liam Girdwood pointed me to (not used) UCM git tree at ALSA Project server. So finally I spent some time and [sent Ubuntu ones for merging](http://mailman.alsa-project.org/pipermail/alsa-devel/2013-May/061891.html).
I also got [newer profiles for OMAP4 devices](https://bugs.launchpad.net/ubuntu/+source/alsa-lib/+bug/1178772) and some updates for Chromebook ones.
The idea is to collect UCM profiles, keep them in one place and share in each distribution packages. So if your hardware has profiles created then join us to make users life easier.
