Actually I am planning to set up Android as guest in Xen.
I see.

In order to enable sound in the Android guest, I need to passthrough the audio codec device which communicates through the I2C bus. For BE/FE scheme, I think sharing the internal DMA and clock would pose problems. So I'm going to go ahead with the device passthrough way.
Passing through I2C bus to guest domain would not be enough to get sound in Android. You would face more dependencies, and they may appear not solvable.

Any thoughts or inputs you can possibly give regarding this use case will be very helpful and valuable.
We are using PV Audio solution for such a task:
