The one i use is broadcom chipset i guess (Samsung Grand). Any pointers based on the above logcat message will be helpful ? I wonder if there is any Android/Samsung mailing list that can answer this topic.
I am expecting some developers who worked on the above said platform will be on this list.

I am trying to bring up Android Accessory Audio in my Samsung Grand mobile.. I am using a Linux PC for the same. The mobile re-enumerates in AOA mode with an Audio interface. But when I play song, I see nothing on the bus. I can see an AOA audio device entry in /proc/asound/cards. The mobile runs Android JB
If the card is present in /proc/asound/cards, alsa detected it just fine, and you have to look at the Adroid sound system in order to find out why it's not used. Unfortunately, Android decided not to use any of the ALSA userspace code but reinvented the wheel, for which simple tools like aplay are unavailable.
Actually quite a few devices come with either tinyalsa or full alsa-lib.
Qualcomm-based ones are the exception.
