Hi, I’m also getting the „amixer: Control hw:RPiCirrus open error: No such device“ error.
I’m running an old Wolfson Ver:A02 on Legacy Version 2.46 and Raspberry PI B.
When i select soundcard „Old Wolfson Cirrus Logic (kernelchange)“ it changes after reboot to „Cirrus logic new (kernel 4.4.+)“.
And I’m getting the „amixer: Control hw:RPiCirrus open error: No such device“.
