Wait for sbp's comment.

Hi Mucke.

We are in the same boat as I would also like to support the Wolfson audio card in the piCorePlayer.

However, as far as I understand the status it is not supported officially in the kernel yet. There seems even to be some uncertainty among the developer of the raspberry kernel whether it is merged into the 3.12.y kernel https://github.com/raspberrypi/linux/pull/672 . But I'm quite sure that it is not supported by the 3.16.y kernel which is the basis for the current piCore.

So  I think at the moment it is very difficult to get WAC running in a piCore environment as it is even not properly supported in the official raspberry kernels which are used by Bela to build piCore. So we/you will have to wait for Wolfson to develop their drivers so the can be properly incorporated.

I think that such a well known audio company should have done that from the very beginning. Look at the smaller companies like HiFiBerry or IQaudIO they managed to get their cards supported even before they release their actual hardware.

Kernel 3.17.0 supports Wolfson. Will make a new alpha available if it works.

bmarkus:
Not suprized, 3.17.0 doesn't build due to error in Wolfson code. Usual issues with x.y.0 releases. Upstream ticket opened.

bmarkus:
6.0alpha501 built on kernel 3.17.0 uploaded to http://www.tinycorelinux.net/6.x/armv6/test_releases/ alsa and wireless modules are in the repo. Please try specially the Wolfson audio.

Let me know your findings.
