I have Intel realtek embedded audio. I am using the SPDIF digital output to my sound system.
Up to kernel-3.7.9, this worked. After upgrading to kernel-3.8.3, this audio stopped. I upgraded to 3.8.4, and still not working.
I did see this in the boot log:
I didn't see this with the 3.7.9 kernel.
Is this a bug with the 3.8.x kernels? Something definitely changed.
Any help greatly appreciated.
TIA
