Hi Arjan,
Can you please pull alsa loop driver in meego kernel, following commits (in
chronological order) in Linus's tree add this driver.
This is required to enable WiDi feature in meego.
Please enable the config for this in meego kernel

The snd-aloop module allows redirecting of the PCM playback in the
kernel back to the user space using the standard ALSA PCM capture API.
The module also allows time synchronization with another timing source
and notifications of playback stream parameter changes.

In a special case, some old samples are left in the capture ring buffer.
Fix it.

This patch fixes the hw_params restrictions when first (or playback) stream
sets the final hardware parameters. Also, fix the hw_params checking
in the trigger callback.

In some circumstances (the rate shift value was changed), the irq_pos
value may be higher than the fraction value in the timer start function.
Check for it.
Also, to avoid value overflow, decrease maximum period size.

On SMP machines, the cable->running update must be atomic, otherwise
stream is not started correctly sometimes.
