I have a RPi2 and a Cirrus Logic Audio Card. For the installation I used Method A: Complete image install from the Cirrus Logic Audio Card User Documentation. When finished the card was recognized and I could control audio playback and record by using the scripts.
After rebooting the RPi the card is no longer recognized: aplay -l doesn't show it and when using a script I get: amixer: Control hw:sndrpiwsp open error: No such device
The config.txt is showing dtoverlay=rpi-cirrus-wm5102-overlay and there is a rpi-cirrus-wm5102-overlay.dtb in the overlays folder.
I'm a RPi user beginner and need an advice how to figure this out.
Thanks a lot,
Martin
