Re: Wolfson audio card

Hi again m.rambaldi. Because I was interested, I tried to apply the patches to the foundation 3.10.y kernel (3.10.38). They did not apply cleanly but with some manual intervention the thing eventually compiled. I have, however, no way of testing the result. You may well be better off using the stock...

Re: Wolfson audio card

Hi m.rambaldi. I have had lots of success with koalo's i2s drivers in Arch (albeit) with other sound modules. They do require a kernel recompile though. For the Wolfson card, I can see that the link you provided refers to "Driver Source Code" which contains patches for the 3.10.25 kernel. If you are...

I have updated the build script for the mods to espeak so that it should now work on both Arch and Raspbian. The link is the same as I posted above.

Hi there.

I am being logged out after a few seconds and the login keeps on asking for the captcha (as if there have been repeated login attempts using my account). Is this related to the work being done?

Also I think, the captcha could be made a little more difficult!

Howdy.

I built this with Arch: http://www.raspberrypi.org/forums/viewt ... 8&p=478852.

The GUI development was a bit involved but worked out quite nicely in the end.

Although I used Python2, you should have quite a few pointers.
