Sorry I am not going to make it the conf!

I will send out the status of offload, challanges, drivers (not many) before you
guys start the meeting. Together with Eric's usermode and Android update it
should cover well. I would have loved to see something on PA side too.

Arun any plans to implement support for compressed offload?

We are working on effect offloading part and creating framework in sound for
DSPs to do that. Hopefully we should be able to push an RFC before this week and
you guys with Pierre can discuss this over the meeting and provide feedback for
future work on this topic

I want to bring the attention to DAPM framework bugs. Somehow recently I
stumbled on quite a few occasions of DAPM bugs and the best part was that the
fix was already availble upstream, ported to stable later version than I had or
NOT ported. Mark, can you pls help by ensuring the right fixes are marked to
stable so that users dont get hit by it!
