I can't say how easy it will be to compile the kernel for Wolfson support, but the instructions seem to be well-documented.

I take it you've already read through this page?

Hi tekmeister I completely agree with you, I have wasted Approx 2 Weeks getting things running .

The problem with Jasper Disk image is that it does not have Wolfson's Audio card drivers, and i haven't tried my hands on compiling a Linux kernal yet ! So, what would be you advice :
Do I go for Jasper Disk image + compile a raspbian kernel with the drivers included ?
OR
Go with the Wolfson's image + get Jasper configured properly without bricking the image

Speaking from experience, installing Jasper on a RPi can be fiddly and take some time to get going. The Jasper website does offer a pre-built disk image. Perhaps you could start from that and then install the Wolfson drivers?

HI Guys, due to some unavoidable circumstances My review will be delayed.
Further, I had a question ?
I have preloaded Wolfson's pre-compiled image from Element14 community page, and it works fine. But, when i try configuring jasper it bricks the image and i can use any audio device on my pi anymore, any help !! as i cant compete my project without this.

Had anyone noticed a significant amount of latency?
I don't' know that's why I ask.

I was accepted into the RoadTest but still have not receive the product. I'm really excited though. I have some great ideas to expand my Pi.

I posted the update on another thread. Sorry forgot to update the email stated they were on track to release to Raspbian by end of Q2 so next month. Trying to hold out to review then.

See the comment here. Note 2 months to review deadline would be sometime first week of July.
