sound again [was: Re: xf4 bug report]

Hi Steffen,

I think we should take this off-list... (it's getting to be a bit
long-winded)...

Ben, Franz (if you are 'listening' or have an interest) let me know and I'll
cc you otherwise we'll report back when there's some solution.

Good that's definitely the back-port code...

You've abbreviated this (I hope)...

Good, it's recognised your Burgundy chip...

The rest looks OK too...

Now, I'll have a quick look at the amp-enable code (again) - that did have a
problem at one point.

I'm out (on paid work :) tomorrow... so not much action 'till late...

Iain.
