piCore and Wolfson Audio Card
Mucke:
--- Quote --- For Wolfson wait a bit for piCore 6.0 with 3.16.3 kernel with Wolfson support.

May I kindly ask about the intended release date?
Or is there another way to get it running before piCore 6.0 ?

If you dot need GUI, only the usual console tools, it is available:
http://www.tinycorelinux.net/6.x/armv6/test_releases/
Archive contains the kernel and initrd with config files, just copy them to /mnt/mmcblk0p1 overwriting existing files. After reboot install kernel module extensions from the repo and update system with tce-update.
Please note it is an alpha test.
Let me know your result.

Sorry for my dumb question but what do you exactly mean by "kernel module extensions". I understand you mean tcz extensions but which ones? Or which ones are not included in comparison to piCore5.3.1 ?

Today I have got my Wolfson Audio Card.
In the meantime I have got the system running as intended with the onboard sound.
But the WAC is not recognized by piCore 6 alpha.
The driver logic seems to be quite different compared to usual ALSA drivers (it seems no modprobe of the driver)
So there is no corresonding snd-... module in alsa-modules...tcz
Unloading the onboard sound snd-bcm2835 results in 'no soundcard' with cat /proc/asound/cards
A parallel setup of a Raspbian system recognizes the WAC though. Also ALSA reports the soundcard capabilities e.g. by amixer controls.
cat /proc/asound/cards then reports

So piCore 6 alpha is not working properly with the WAC right now.
Can you check? Do you need some further information?
What can I further check on my side?
