Some Audio discoverment!
I've been researching for a while for some Audio base, as tinyAlsa seems to be broken on Ice Cream Sandwich. As far as I've investigated, our device use kind of the same Audio it was used on Nexus S. It is not the same though, but Nexus S used on Gingerbread audio ALSA. Audio system is really easy on Nexus S sources, although I don't think it will be as easy on our phones.
Nexus S ICS source is open sourced, as it is nexus device. Here are the files it uses:
I'll try to implement this source on our littles Broadcom Galaxy devices, but I'm not sure it will work I'll still give a feedback out here!
Stay tuned for more news!
